The LVK chip features four terminals, also known as a "Kelvin" configuration. This configuration enables current to be applied through two opposite terminals and a sensing voltage to be measured across the other two terminals, eliminating the resistance and temperature coefficient of the terminals for a more accurate current measurement. Isolating the voltage and current terminals (see schematic) facilitates a very accurate current measurement. Ohmite's proprietary technology offers an excellent Temperature Coefficient of Resistance (TCR) even for very low resistance values. The resistive element consists of a durable, anti-corrosive metal alloy that combines reliable performance with the ability to withstand harsh environments.

The HVF Series offers unmatched performance in comparison to standard chip resistors. Its unique design provides lower voltage and temperature coefficients, less noise, tighter tolerances, better stability, higher resistance values, and higher voltage ratings. HVF is available in convenient 1206 and 2512 footprints.

Coating Silicone Solder Pad Material Silver (PdAg) Note: HVF Series should not be used with tin-lead based solder compositions. Only silver-based solder compositions are recommended. Care should be taken in the selection of the solder flux contained in the solder paste. Some pastes are "corrosive" and can damage the coating and also the resistive layer during the soldering process at high temperature. PCBs must be properly cleaned to remove any layers of moisture containing halides below the resistor. We recommend Halide Free (or Halogen Free) solder pastes, containing for example ROL0 or similar. It is advisable for the PCB layout to provide a slot, or air gap, underneath the downward facing resistor element, thereby increasing insulation resistance and reducing the possibility of capacitive coupling to the PCB. Under no circumstances should any copper trace be present in the layout directly under the resistive element.

The resistor body incorporates fins identical to a heatsink. These fins, as with a heatsink, increase the surface area of the part and allow for greater power dissipation. This unique design allows a small footprint for the SMD device and a high power dissipation. These 5 and 7 watt resistors are extremely stable with a load life drift of only 1%. A special flat has been designed in to the part for pick and place operations.

This four-terminal version of Ohmite's 10 Series resistor is specially designed for use in a Kelvin configuration, in which a current is applied through two opposite terminals and sensing voltage is measured across the other two terminals . The Kelvin configuration enables the resistance and temperature coefficient of the terminals to be effectively eliminated. The four terminal design also results in a lower temperature coefficient of resistance and lower self-heating drift which may be experienced on two-terminal resistors. The requirement to connect to the terminals at precise test points is eliminated, allowing for tighter tolerancing on the end application.

These shunt resistors are specifically designed for low resistance applications requiring the highest accuracy and temperature stability. This Four Terminal version of Ohmite's 60 Series Resistor is specially designed for use in a Kelvin configuration, in which a current is applied through two opposite terminals and sensing voltage is measured across the other two terminals. The Kelvin configuration enables the resistance and temperature coefficient of the terminals to be effectively eliminated. The four terminal design also results in a lower Temperature Coefficient of Resistance and lower self heating drift which may be experienced on two terminal resistors. The requirement to connect to the terminals at precise test points is eliminated, allowing for tighter tolerancing on the end application.

Model TFSC is rated for 4kV, so the peak voltage of 3.5kV is acceptable. 1 Ea = -- CV2 = 6.1J 2 ta = R C = 1 ms 6.1J Er = --- x 100 = 55% 11J According to the pulse chart, an energy ratio of 55% for a pulse width of 1ms falls well above the energy curve. The limit is actually located around 25-30%. Model TFSC cannot be used for this application. A bigger model should be chosen, for example TFSD. Model TFSD, 1KOhm, can be used for this application because we have an energy ratio Er of 18%, which is below the energy curve. 6.1J Er = --- x 100 = 18% 33J Maximum Individual Pulse Rating 1000 Energy Rating % Although Ohmite's TFS Series resistors have been specially designed and developed to absorb much more energy than standard resistors, pulses and transients require special consideration since they cause an instantaneous temperature rise in the resistor film. This application note can guide you through these considerations. For applications with transients, pulses or surges the following must be considV 2t ered: V E = --- R 1.

Calculate the energy ratio in percent (Er) between the nominal energy rating of the model you have chosen V2t V E = --- 3R (see table) and the single pulse energy in your application (Ea from t step 2) using the formula: Ea Er = -------- x 100 V2t V E = --- Enominal 3R 4. Refer to the Pulse Chart. On this t chart find the point where the energy E = Energy (joules) ratio (Er), found at step 3, and time t = Time (seconds) (ta) coincide. Qualify that this point V = Voltage (volts) falls below the maximum pulse R = Resistance (ohms) energy curve. If the point is above C = Capacitance (farads) the curve a bigger model should be chosen. 100 10 1 0.1 1s 10s 100s 1 ms Pulse Width 10 ms 100 ms O r d e r i n g i n f o r m at i o n RoHS Compliant TFSA100KJE Series Energy Rating joules A = 6 D = 33 B = 9 E = 44 C = 11 F = 55 Ohm Value Example: 100R = 100 2K40 = 2400 Tolerance F = 1% G = 2% J = 5% K = 10% Standard Part Numbers for TFS Series Ohms Tol. 100 100 220 270 470 470 680 750 1,000 1,000 1,500 2,200 2,700 4,700 4,700 4,990 5,000 6,800 10,000 10,000 16,000 20,000 20,000 22,000 27,000 47,000 50,000 51,000 75,000 6 Joules 0.5 Watts 9 Joules 0.5 Watts 11 Joules 0.75 Watts 33 Joules 1 Watts 44 Joules 1.5 Watts 1% TFSA100RFE 5% TFSB100RJE TFSD100RJE 1% TFSA220RFE 5% TFSA270RJE TFSC270RJE TFSD270RJE 1% TFSA470RFE 5% TFSB470RJE TFSE470RJE 5% TFSA680RJE TFSC680RJE TFSE680RJE 5% TFSB750RJE TFSD750RJE 1% TFSA1K00FE 5% TFSA1K00JE TFSB1K00JE TFSC1K00JE TFSD1K00JE TFSE1K00JE 5% TFSA1K50JE TFSC1K50JE TFSD1K50JE 1% TFSA2K20FE 5% TFSB2K70JE TFSE2K70JE 1% TFSA4K70FE 5% TFSA4K70JE TFSC4K70JE TFSD4K70JE 1% TFSA4K99FE 5% TFSA75K0JE 5% TFSB6K80JE TFSE6K80JE 1% TFSA10K0FE 5% TFSA10K0JE TFSB10K0JE TFSC10K0JE TFSD10K0JE 5% 1% TFSA20K0FE 5% TFSB20K0JE TFSD20K0JE 1% TFSA22K0FE 5% TFSA27K0JE TFSC27K0JE TFSE27K0JE 1% TFSA47K0FE 5% TFSA50K0JE 5% TFSB51K0JE TFSC51K0JE TFSD51K0JE 5% TFSE75K0JE 100,000 1% TFSA100KFE 100,000 5% TFSB100KJE TFSC100KJE TFSD100KJE 1-866-9-OHMITE * Int'l 1-847-258-0300 * Fax 1-847-574-7522 * www.ohmite.com * info@ohmite.com 59 55 Joules 2 Watts TFSF100RJE TFSF270RJE TFSF680RJE TFSF750RJE TFSF1K00JE TFSF1K50JE TFSF10K0JE TFSF16K0JE TFSF20K0JE TFSF51K0JE TFSF100KJE TP Series High Energy Thick Film on Alumina Substrate Fe a t u r es TP Series high energy resistors offer the user the benefits of non-inductive performance and high power density.

Most wirewound resistors are wound with the objective of meeting the stated power (wattage) rating and keeping cost low through the use of automatic winding equipment. Typically, manufacturers will allow substitution of resistance wire, depending on material availability. On tight tolerance wirewounds some type of abrasive adjustment to the resistance wire is often used to maximize production yields. Both of these procedures can adversely affect the joule rating and fusing current of a wirewound resistor, and this is often the reason that the manufacturer does not publish a fixed joule rating. Ohmite High Energy Wirewounds are hand wound in order to maintain the tightest possible pitch (space between windings) and thereby maximize the mass of the resistive element. Since no wire substitutions are allowed, and no abrasive adjusting is permitted in this family, Ohmite can publish a fixed joule rating and fusing current for each part number in the series. This technique can be applied to any wirewound product. In order to provide the broadest selection of packaging, Ohmite has developed standard offerings in three different package types-axial, SMD, and heat sinkable. Other sizes and types can be quoted on request, such as tubular power resistors.

These resistors should be handled by the terminals, unless gloves are worn. Fingerprints on the surface of the resistor will attract contaminants and moisture, which will cause a parallel resistance path, reducing the resistance value of the device. If cleaning should become necessary, use isopropyl alcohol and lightly wipe dry with lint free tissues such as Kimwipes. dimensions 0.9"/ 22.9 mm min. 0.9"/ 22.9 mm min. 1.875"/47.63 mm max. 0.198"/5.0 mm dia. max. 0.025" .002 0.64 mm o r d e r i n g i n f o r m at i o n RX-1M1006FE Hi-Meg Series 72 Ohms First 3 digits are significant; 4th digit is multiplier (# of zeroes to follow).

Wirewound, 5% Tolerance Standard When you need the highest quality wirewound axial terminal resistors available, choose Ohmite's 90 Series resistors. They are manufactured by a unique process that molds the vitreous enamel over the resistive element, helping to ensure consistent dimensions. This uniformity permits 90 Series resistors to be mounted in clips, creating a heat-sinking benefit (see next page). The durable vitreous enamel coating, which is totally lead free, permits the 90 Series resistors to maintain a hard coating while operating at high temperatures. Mechanical integrity is enhanced by the all-welded construction. Fe a t u r es * Molded Construction provides consistent shape and size (Permits mounting in clips which extends power rating). * Meets MIL-R-26 requirements for insulated resistors. * All-welded construction. * Flame resistant lead free vitreous enamel coating. * Higher ratings in smaller sizes. * Heat sink mounting clips available. * RoHS compliant; add "E" suffix to part number to specify.

The OA series will no longer be available for new orders after 8-30-14. After this date existing stock will be sold until depleted. Ohmite's Little Demons are small, reliable carbon composition resistors with exceptional strength. They are made tough by a molding process that combines the terminals, insulation and resistive element into an integrated unit. Along with their small size, Little Demons perform with low noise, dissipate heat rapidly and offer high temperature stability. Color codes are readable even after prolonged use thanks to a very durable coating that resists abrasions and chipping normally associated with automatic insertion equipment.

The extrusion is cut to length, leads inserted, cured, and marked to form a finished resistor. The carbon and binder mixture is adjusted to produce different resistance values. The resistors are sorted for 5%, 10%, and 20% tolerance values. Carbon composition resistors are able to withstand larger short-term pulses and higher voltages than film resistors and are virtually impervious to ESD events (Electro-static discharge). Carbon composition resistors are also sensitive to moisture and, therefore, storage recommendations should be adhered to. Generally, any moisture absorbed during storage will be "baked out" during the soldering operation. If the product is stored properly the resistance shift during the soldering operation will be minimal, less than 2% or 3%. Carbon composition resistors are highly hygroscopic and changes in resistance value can occur if too much moisture is absorbed. For this reason, it is recommended not to use water or water-soluble solvents to clean these components. Alcohol or hydrocarbon solvents are recommended for rinsing. b a k e p r oce d u r e A.

These planar packages yield space saving, 10W/in2 power densities that require over 50% less board space than other radial packages. Convection cooling is maximized by the planar package configuration which dissipates heat well above board level. Ohmite's power chip resistors have a 125% higher operating temperature range than competitive product of similar design. High temperature solder and in-process plating keep terminations secure under self-heating effects by preventing re-flow from full power operation. Flexible packaging schemes make these resistors ideal for power supplies, audio amplifiers, video flyback, and other power control applications.

Specify our Edgewound design for very low resistance and high power capacity. When higher resistance with lower power capacity is required use our Round Wire design. These resistors are constructed of a heavy resistance alloy mounted on ceramic insulators and supported by a metal mounting bracket. Metal parts, except for the resistance element, are heavily plated to prevent oxidation at high operating temperatures and to prevent corrosion. The mounting bar is slotted on each end to facilitate installation. Edgewound units provide clamp-type terminals, permitting a reliable connection which can be moved along the resistive element to obtain intermediate values. c h a r a cte r i st i cs Current Rating Continuous duty as listed on following page.

They are available in a variety of ohm and current ratings common to transit use. A sturdy welded steel frame supports the refractory insulators. The frame is finished with a zinc chromate conversion for corrosion resistance. The ceramic insulators separate turns of the resistance elements from each other and the frame. The resistance element is a stainless steel strip, used for its corrosion resistance, negligible temperature coefficient, and Ohms per foot vs. current carrying capacity. The resistance element is created by edgewinding a stainless strip into a continuous coil of the proper length. Zinc plated terminals welded to the resistance element complete the assembly.

Power limitations for high resistance values: When resistance exceeds the resistance values listed below, derate the Power Rating by 25% to improve reliability: Power Resistance No power rating value derating necessary for ratings 12W 4,500 higher than 25W 9,000 100W. 50W 20,000 75W 100W Temperature 260 ppm/C coefficient Dielectric 1000 VAC: 12 to 100 watt rating. 3000 VAC: 175 and 225 watt ratwithstanding ing (measured from terminal to mounting bracket) voltage Max. amps To calculate, use the formula P/R. 1-866-9-OHMITE * Int'l 1-847-258-0300 * Fax 1-847-574-7522 * www.ohmite.com * info@ohmite.com 107 35,000 50,000 210 Series Dividohm(R) Vitreous Enamel Adjustable Power dimensions (in. / mm) Series Wattage L D C Core Code Standard Terminal D12 12 1.75 / 44.4 0.313 / 7.94 0.188 / 4.76 D 57 D50 50 4.0 / 101.6 0.562 / 14.3 0.313 / 7.94 K 40 D25 D C 25 D75 D100 L D175 D225 D500 D1000 2.0 / 50.8 75 0.562 / 14.3 6.0 / 152.4 100 0.562 / 14.3 6.5 / 165.1 175 0.750 / 19.1 8.5 / 215.9 225 500 1.125 / 28.6 10.5 / 266.7 1.125 / 28.6 20.0 / 508.0 2.50 / 63.5 12.0 / 304.8 1000 2.50 / 63.5 0.313 / 7.94 K 0.313 / 7.94 40 K 0.50 / 12.7 40 M 0.75 / 19.1 40 P 0.75 / 19.1 1.75 / 44.5 46 P 46 S 45 S 1.75 / 44.5 45 o r d e r i n g i n f o r m at i o n Made-to-order Parts Coating Blank = Vitreous C = Centohm S = Silicone RoHS Compliant Series Wattage Tolerance J = 5% K = 10% Core Diameter See "Core and Terminal Selection" Ohms 1R0 = 1 250 = 250 1K0 = 1,000 25K = 25,000 25K5 = 25,500 Terminal Type See "Resistor Terminals for Tubular Cores" Wattage Coating 210 = Vitreous 410 = Silicone Ceramic 610 = Centohm RoHS Compliant See 270 series custom core and terminal info Tolerance J = 5% K = 10% Ohms R500 = 0.500 1R00 = 1 250R = 250 1K00 = 1,000 25K0 = 25,000 25K5 = 25,500 150 200 250 300 400 500 750 800 1,000 1,250 1,500 2,000 2,500 = Standard values; check availability at www.ohmite.com 108 ---150E ---200E ---250E ---300E ---400E ---500E ---750E ---800E ---1K0E ---1K25E ---1K5E ---2K0E ---2K5E 3,000 4,000 5,000 6,000 7,000 7,500 10,000 12,000 15,000 20,000 25,000 50,000 100,000 50K and 100K resistance values involve very fine resistance wire and should not be used in critical applications without burn-in and/or thermal cycling. 1-866-9-OHMITE * Int'l 1-847-258-0300 * Fax 1-847-574-7522 * www.ohmite.com * info@ohmite.com D225K--- 225 D175K--- 175 D100K--- 100 D75K--- 75 D25K--- 25 D50K--- 50 Part No. Prefix Suffix ---3K0E ---4K0E ---5K0E ---6K0E ---7K0E ---7K5E ---10KE ---12KE ---15KE ---20KE ---25KE ---50KE ---100KE D12K--- 12 Ohmic value D1000K---1000 D500K--- 500 D225K--- 225 D100K--- 100 D175K--- 175 D75K--- 75 D25K--- 25 D50K--- 50 D12K--- 12 Ohmic value D75K--- D25K--- D50K--- D500K--- 500 D175K--- 175 D100K--- 100 75 25 50 12 D12K--- D225K--- 225 Part No. Prefix Suffix Wattage Part No. Prefix Suffix 1.0 ---1R0E 2 ---2R0E 3 ---3R0E 4 ---4R0E 5 ---5R0E 7.5 ---7R5E 10 ---10RE 15 ---15RE 20 ---20RE 25 ---25RE 50 ---50RE 75 ---75RE 100 ---100E Wattage Ohmic value Wattage D1000K---1000 Standard Values 250 Series `Thin' Stackohm(R) Vitreous Enamel Power When limited space is a consideration, choose Ohmite's "thin" stackable 250 Type resistors. These oval-shaped ceramic-core resistors feature a low profile to permit installation in spaces with height restrictions. They are also equipped with integral mounting brackets so they can be fastened to a chassis and stacked in locations with limited surface area. When properly fastened, the mounting brackets add a heat sinking benefit resulting in a smaller size per watt. Durable 250 Type resistors are fully welded and coated with lead free vitreous enamel.

These large, heavyduty resistors are designed to withstand frequent start-stop cycles characteristic of motor starting, dynamic braking and other similar applications. Special order units are available to accommodate up to 1500 watts. Corribs(R) are manufactured with corrugated resistive wire. To accelerate cooling, the wire is securely fused to the ceramic core by the protective vitreous enamel coating to improve durability. Corrib resistors are hollow-core units which can be securely fastened to chassis surfaces with thru bolts and brackets. Fe a t u r es * Also available in Centohm or Silicone coating. Consult Ohmite. * Ribbed construction aids in rapid cooling. * Designed for equipment requiring low resistance loads at low ohmic values and high current capacity. * Especially constructed for motor starting, dynamic braking, etc. * RoHS compliant product available.

This results in a possible maximum increase in diameter of 0.188 (4.763mm) for low resistance, 1.125 (28.575mm) O.D. core resistors and larger; 0.156 (3.969mm) for resistors with smaller diameter cores. On all high resistance units the increase is generally less than 0.125 (3.175mm).

Butt Weld of Tab to A tab material of 800 ohm alloy (the same as the Terminal resistance wire) is butt welded to the terminal and molded deep into the resistor bobbin. This design parameter assures the least possible DC transients due to thermal EMF. Bobbin Design The ratio of the height of the Pi wall to the width of the Pi and to the diameter of the bobbin mandrel are critical to the basic stability of a wirewound resistor. These parameters are optimized for each wire size, wattage size and range of resistor values. Encapsulation Both the bobbin and the final encapsulation material Material are thermosetting alkyd polyester. The resulting resistor is virtually a homogeneous mass with an identical coefficient of expansion which is unaffected by the most violent of temperature cycling. All types are unaffected by application of solvents. Terminal Materials The standard terminal material is hot solder dipped copper (C5N).

WFH is mounted on a heat sink: A. The thermal resistance RTH of the heat sink is known, T = WMAX x (RTH4 + RTH) Check that: TMAX = WMAX x (RTH + RTH3 + RTH1) + TAMB <220C B. The Temperature of the Heat Sink is known, T = WMAX x RTH4 + TH Check that: TMAX = WMAX x (RTH1 + RTH3) + TH <220C 2. WFH is mounted without a heat sink: Check that: TMAX = WMAX x (RTH1 + RTH2 ) + TAMB <220C Where: WMAX = Maximum reguired load in resistor TMAX = Maximum hot spot temperature reguested in resistor (TMAX <220C) The lower TMAX the higher reliability and lifetime.

Pleased follow these guidelines when designing TAP system: * Heats sink plate (base plate of the resistor) temperature must be monitored to establish proper de-rating. Best technique is to attach a thermocouple to the side of the base plate of the resistor. Temperature of plastic housing or heat sink cannot be used to establish rating of the resistor. Usage of laser thermometers should be avoided. * To obtain a power rating of 1000W or 2000W, the bottom case temp must not exceed 85C. This can only be achieved if the thermal conduction to the heatsink Rth-cs<0.025K/W. This value can be reached by using thermal transfer compound with a heat conductivity of 1W/mK. The flatness of the cooling plate must be better than 0.05mm overall. The roughness of the surface should not exceed 6.4m. * Due to very high power density, only liquid cooled heat sinks are recommended for applications when >300W power rating is desired. * Properly designed heat sink should have more than 2 cooling pipes under the surface of the TAP resistor.

The resistor element is packaged with plastic insulators, and quickconnect terminals in a symmetrical aluminum profile for easy heat sink mounting. Special tapped configurations are offered to reduce on board component count. Efficient thermal packaging provides improved heat conduction to the heat sink. Self-insulating package design increases voltage withstanding characteristics when compared to traditional aluminum housings. The in line mounting profile makes the TL Series easily adaptable to most heat sink systems. Thermal compound is always recommended when heat sinking.

The unique design (Patent Pending) combines tin plated, solderable rods with an aluminum extruded heat sink body. These rods (or "rollers") are mated mechanically to the heatsink by forging to reduce the thermal resistance between the heatsink body and the solderable feet. Specifically designed for use with the increasingly popular TO-252, TO-263 and TO-268 packages, the D Series affords the user superior thermal performance over the more common stamped aluminum heatsinks. By eliminating the staking joint typically used in stamped heatsinks, the resulting air gap and thermal "bottle-neck" is also eliminated, while surface area for cooling is maximized with the extruded fins of the D Series body. Fe a t u r es * Increased surface areas by 3 times therefore thermal performance up to 300% over the aluminum stamped heat sinks on markets * Light weight aluminum construction allows faster pick and place assembly reducing the manufacturing cycle time * Radius mounted "Rollers" are designed for maximizing heat transfer from the component and avoiding the thermal "bottle-neck" seen in stamped and staked heatsinks. * Available in bulk packaging or tape & reel (250 units per reel * RoHS Compliant He a t d i ss i p a t i o n 800 Air Velocity (ft./min.) 1000 50 14 12 50 101 & 201 45 10 40 8 35 301 6 30 Case Temp.

No. 7,151,669), high performance, low cost, configurable, scalable and compact heat sink with matrix clip system for TO-247 and TO-264 packages. This powerful heat sink provides the easiest assembly, largest surface area and smallest footprint. It is the ideal type of heat sink for high power density and small size (1U or 2U) electronic packaging with forced convection cooling. * Minimum assembly cost and labor. Spring Clips make the mounting holes and fasteners obsolete in assembly operations & reduce costs. * Maximum Thermal Transfer. Maximum surface area per unit volume, efficient cooling fins & consistent mounting force reduces thermal resistance * Maximum Repeatability. Constant spring force over repeated assembly/disassembly * Maximum Reliability. Resilient spring action locks electronic component in place. Fewer parts in assembly and no fasteners and washers required. Prevent short circuit by eliminating metal particles generated from hardware or thread tapping * Design Flexibility. Maximum flexibility for dynamic device locations and power up grading. "Configureto-Fit" & "Scale-to-Meet" options give designers the total freedom to configure the heat sink to fit their packaging designs and to scale the heat sink to meet their power dissipations. se r i es s p ec i f i c a t i o n s Thermal Surface Area Weight Resistance Part No. (in2/mm2) (oz./g) (c/w)* MV-102-55E 45 / 29,097 2.2 / 63 6.0 MA-102-55E 45 / 29,097 2.2 / 63 5.2 MV-101-27E 22 / 14,284 1.1 / 31 9.6 MA-101-27E 22 / 14,284 1.1 / 31 8.0 MV-302-55E 76 / 49,218 4.7 / 134 3.6 MA-302-55E 76 / 49,218 4.7 / 134 3.0 MV-301-27E 37.3 / 24,161 2.3 / 66 5.5 MA-301-27E 37.3 / 24,161 2.3 / 66 4.6 * R-thetac-a for 18W dissipation total for two devices in natural convection C h a r a cte r i st i cs Heat Sink Aluminum Alloy 6063-T5 or Equivalent with either degreased or black anodized finish.

Rheostat model P N R U 51/2" 33/4" 51/2" Resistor Selection Application Notes R esistor F acts and F actors A resistor is a device connected into an electrical circuit to introduce a specified resistance. The resistance is measured in ohms. As stated by Ohm's Law, the current through the resistor will be directly proportional to the voltage across it and inversely proportional to the resistance. The passage of current through the resistance produces heat. The heat produces a rise in temperature of the resistor above the ambient temperature. The physical ability of the resistor to withstand, without deterioration, the temperature attained, limits the operating temperature which can be permitted. Resistors are rated to dissipate a given wattage without exceeding a specified standard "hot spot" temperature and the physical size is made large enough to accomplish this. Deviations from the standard conditions ("Free Air Watt Rating") affect the temperature rise and therefore affect the wattage at which the resistor may be used in a specific application. S election R equires 3 S teps Simple short-cut graphs and charts in this catalog permit rapid determination of electrical parameters. Calculation of each parameter is also explained. To select a resistor for a specific application, the following steps are recommended: 1 . (a) Determine the Resistance. (b) Determine the Watts to be dissipated by the Resistor. 2 . Determine the proper "Watt Size" (physical size) as controlled by watts, volts, permissible temperatures, mounting conditions and circuit conditions. 3 . Choose the most suitable kind of unit, including type, terminals and mounting. determine resistance and watts Ohm's Law (a) R = VI or I = V R or V = IR Ohm's Law, shown in formula form above, enables determination of the resistance when the required voltage and current are known. When the current and voltage are unknown, or the best values not decided on, at least two of the three terms in Ohm's Law must be measured in a trial circuit. (b) P = I R or P = VI or P = V R Power in watts, can be determined from the formulas above, which stem from Ohm's Law. R is measured in ohms, V in volts,I in amperes and P in watts. 2 2 S tep 2 Why Watts Must Be Accurately Known Stated non-technically, any change in current or voltage produces a much larger change in the wattage (heat to be dissipated by the resistor). Therefore, the effect of apparently small increases in current or voltage must be investigated because the increase in wattage may be large enough to be significant. Mathematically, the wattage varies as the square of the current, or voltage, as stated in the formulas (b). For example, an increase of 20% in current or voltage will increase the wattage 44%. Figure 1 below graphically illustrates the square law relation. Hence, the actual current must be used in figuring the wattage and the increase in wattage due to apparently small changes, then determined in order to select the proper size resistor. Allowance should be made for maximum possible line voltage. 300 200 100 0 0 200 100 Percent Current or Voltage Fig. 1: Rapid increase of wattage with current or voltage. P ower R ating or P hysical S ize of R esistor A resistor operated at a constant wattage will attain a steady temperature which is determined largely by the ratio between the size (surface area) and the wattage dissipated, The temperature stabilizes when the sum of the heat loss rates (by radiation, convection and conduction) equals the heat input rate (proportional to wattage). The greater the resistor area per watt to be dissipated, the greater the heat loss rate and therefore the lower the temperature rise. The relation between the losses varies for different resistors. Free Air Watt Rating The wattage rating of resistors, as established under specified standard conditions, is defined as the "Free Air Rating" ("Full Rating" or "Maximum Power Rating"). Several standard methods of rating are in use based on different service conditions. The method of both 194 400 Percent Rated Watts 1 S tep the "National Electrical Manufacturers Association" (NEMA) and the "Underwriters' Laboratories, Inc." (UL) can be described as follows: The relation of the "Free Air Watt Rating" of tubular type, vitreous enameled resistors to the physical size, is to be set at such a figure that when operated at their rated watts, the temperature rise of the hottest spot shall not exceed 300C (540F) as measured by a thermocouple when the temperature of the surrounding air does not exceed 40C (104F). The temperature is to be measured at the hottest point of a two-terminal resistor suspended in free still air space with at least one foot of clearance to the nearest object, and with unrestricted circulation of air. A slightly different definition of temperature limit used as a basis for wattage rating, and which results in a slightly higher attained temperature, was originally established in military specification MIL- 1-866-9-OHMITE * Int'l 1-847-258-0300 * Fax 1-847-574-7522 * www.ohmite.com * info@ohmite.com Resistor Selection Application Notes R-26 for wirewound resistors. Characteristic V resistors are required to dissipate rated wattage in an ambient of 25C without exceeding a maximum operating temperature of 350C at the hottest spot. This corresponds to a temperature rise of 325C in a 25C ambient. Although MIL-R-26 permits a 25C greater temperature rise than NEMA or UL, the reference ambient for the latter two is 15C higher. Consequently, the difference in attained temperature between the two systems is only 10C. The curves in Fig. 2 show the relation between temperature rise and wattage for various specifications.

It is also assumed that the temperature rise at a given wattage is independent of the ambient temperature in which this wattage is being dissipated. Therefore, for high ambient temperatures, the operating wattage should be limited in accordance with the curves of Fig. 3. Although the assumption that temperature rise is independent of ambient is not exactly true, the approximation is sufficiently close for all practical purposes and, therefore, has been adopted for Ind. & Comm.

The absolute temperature rise for a specific resistor is roughly related to the area of its radiating surface. It is also dependent upon a number of other factors, however, such as thermal conductivity of the core and coating materials, emissivity factor of the outer surfaces, ratio of length to diameter, heat-sink effect of mountings, and other minor factors. The maximum permissible operating temperature for a given resistor is basically determined by the temperature limitations imposed by the materials used in its construction. Generally speaking, these limits cannot be sharply defined in terms of temperature alone. Other factors such as resistance stability versus time, deterioration rates of insulation and moisture-resistance characteristics, type and size of resistance wire, all enter into consideration of "acceptable service life." For these reasons, the precise temperature limits corresponding to 100% rated wattage are somewhat arbitrary and serve primarily as design targets. In the last analysis, once a wattage rating has been assigned on the basis of an empirical hot spot limit, the verification of its correctness must be established through long term load-life tests based on performance and stability standards rather than the measurement of hot spot temperature. Maximum limits are stipulated for parameter changes as a result of various tests, including a 2000 hour derating purposes. Despite the above variables, figures may be cited in terms of "watts dissipated per square inch of winding surface" for a given temperature rise. For power type resistors operating at 300C rise above ambient, this figure varies between approximately 6.3 watts per square inch for large resistors (175 watt) to about 9 watts per square inch for smaller resistors (12 watt). It should also be observed from Fig. 2 that temperature rise is not directly proportional to wattage dissipated. Note, for example, that at 50% rated wattage, the temperature rise still remains about 70% of that at full rating. The wattage ratings used in this catalog, unless otherwise stated for certain types, are on the basis of a nominal operating temperature of 350C at full rating. There are two general categories of power resistors for which the 350C nominal temperature limit does not apply. One is that class of power-precision resistors where high stability is a salient feature, in which case the operating temperature is nominally limited to 275C. The other category includes all exposed ribbon wire resistors (see description of Corrib(R) and Powr-Rib(R)) which are rated for 375C (675F) maximum temperature rise when measured on the wire per NEMA standards. Temperature Distribution on a Resistor The temperature rise varies (following a curve) along the length of the resistor with the hot spot at the center-top (of a horizontal tube) and the ends at approximately 60% of the maximum temperature rise. The terminals themselves are still cooler. When the resistor is vertical, the hot spot shifts upwards a little and the top end is hotter than the bottom. The standard "Free Air Watt Rating," however, is used regardless of position. 1-866-9-OHMITE * Int'l 1-847-258-0300 * Fax 1-847-574-7522 * www.ohmite.com * info@ohmite.com 195 Resistor Selection Application Notes S teps 3 S elect a R esistor Choose the most suitable resistor meeting the requirements of the application. Standard resistors carried in stock should be considered first. If a suitable resistor cannot be found in the standard sizes or resistance values, then select a non-standard resistor from the range on available sizes (consult factory). A pplication W att R ating To allow for the differences between the actual service conditions and the "Free Air Watt Rating" it is a general engineering practice to operate resistors at more or less than the nominal rating. The details by which such ratings can be estimated are given in the following pages. Most thermal calculations, however, involve so many factors which are usually not accurately known, that at best they are only approximations. The most accurate method of determining or checking the rating is to measure the temperature rise in a trial installation. A thermocouple (made of #30 B & S gage wire) is recommended for the measuring element. Even measurements made with a thermocouple will vary slightly with different samples and techniques. The factors which affect the temperature rise act independently of each other and are summarized as follows: 1. Ambient Temperature As the maximum permissible operating temperature is a set amount, any increase in the ambient temperature subtracts from the permissible temperature rise and therefore reduces the permissible watt load. 2. Enclosure Enclosure limits the removal of heat by convection currents in the air and by radiation. The walls of the enclosure also introduce a thermal barrier between the air contacting the resistor and the outside cooling air. Hence, size, shape, orientation, amount of ventilating openings, wall thickness, material and finish all affect the temperature rise of the enclosed resistor. 3. Grouping When resistors are close to each other they will show an increased hot spot temperature rise for a given wattage because of the heat received by radiation from each other and the increased heat per unit volume of air available for convection cooling. 4. Altitude The amount of heat which air will absorb varies with the density, and therefore with the altitude above sea level. At altitudes above 100,000 feet, the air is so rare that the resistor loses heat practically only by radiation. 196 5. Pulse Operation This is not an environmental condition but a circuit condition. As a pulse of power, when averaged over the total on and off time, results in less heat per unit time than for continuous duty, the temperature rise is affected. This may permit higher power during the pulses. The conditions must be expertly considered for conservative rating. The open-wound "Powr-Rib(R)" resistor construction is most suitable. 6. Cooling Air Forced circulation of air over a resistor removes more heat per unit time than natural convection does and therefore permits an increased watt dissipation. Liquid cooling and special conduction mountings also can increase the rating. 7. Limited Temperature Rise It is sometimes desirable to operate a resistor at a fraction of the Free Air Watt Rating in order to keep the temperature rise low. This may be to protect adjacent heat sensitive apparatus, to hold the resistance value very precisely both with changing load and over long periods of time and to insure maximum life. 8. Other Considerations High Resistance. High resistance units, which require the use of very small diameter wire, generally should operate at reduced temperature for maximum reliability. High Voltage A maximum voltage gradient of 500 volts R.M.S. (705 volts peak) per inch of winding length is recommended under normal conditions. For higher gradients in pulse applications or for other special conditions such as oil immersion, consult factory. High Frequency Non-inductively wound resistors are generally required for use at high frequencies. Military and Other Specifications The special physical operating and test requirements of the applicable industrial or military specification must be considered. Military specification resistors should be ordered by their MIL numbers. 1-866-9-OHMITE * Int'l 1-847-258-0300 * Fax 1-847-574-7522 * www.ohmite.com * info@ohmite.com Resistor Selection Application Notes E nvironmental F actors -- effect on the power rating of components Resistor in Free Air Resistor in Large Box 400 200 Resistor: 100 watt, 0.75 x 6.5" (19.05 x 165.10 mm) In unpainted 0.032" (0.813 mm) thick upainted sheet steel box, no vents Small box: 3.375 x 3.375 x 8" (85.725 x 85.725 x 203.20 mm) Large box: 5.813 x 5.813 x 12.75" (147.65 x 147.65 x 323.85 mm) 300 200 100 Box Temp., Small 100 Box Temp., Large 0 0 0 25 50 Percent Rated Load 75 100 Fig.5: Example of Effect of Size of Enclosure on Temperature Rise of An Enclosed Resistor. 100 Ind. & Comm.

Derating Due to Enclosure The amount of derating required, if any, because of enclosure is affected by a number of factors, most of which are hard to determine accurately. The watts per square inch of surface, size, shape, orientation, wall thickness, material, finish and amount and location of ventilating openings all play a part. Fig. 5 serves to indicate for a particular set of conditions how the temperatures varied with the size of enclosure for a moderate size power resistor. Derating Due to Grouping The temperature rise of a component is affected by the nearby presence of other heat-producing units, such as resistors, electronic tubes, etc. The curves in Fig. 6 show the power rating for groups of resistors with various spacings between the closest points of the resistors, assuming operation at maximum permissible hot spot temperature. If resistors are to be operated at lower hot spot temperatures, the amount of derating for grouping can be reduced.

The attained temperature in service is the sum of the ambient temperature plus the temperature rise due to the heat dissipated in the apparatus.

The NEMA has set up certain standard duty cycles for motor control resistors and the resistor ratings for some of these conditions are shown in Fig. 8. The curves in Figures 10,11,12 and 13 illustrate the more general case of various combinations of on and off time for specified loads up to 1000% for a continuous series of pulses. Intermediate loads can be approximated by interpolation. The "on-time" at which each curve flattens out also indicates the maximum on-time for single pulses (with enough off-time for cooling to ambient). Additional data on single pulses is given by Fig. 9. Resistors will reach about 75% of the rated maximum temperature rise in approximately 5 to 8 pulses and level off at maximum rise in another 10 to 20 cycles, depending on percent load, size, type, etc. Any curve passing above the intersection of the designated on and off-times indicates a percent load which can be used. A resistor operated at the rating of an interpolated curve through the point of intersection would operate at maximum rated temperature rise. The exact temperature rise, of course, varies with each resistor, depending on size, ohms winding, etc. The curves shown indicate the approximate rise for typical units only, as a band or range of values actually exists for each percent load. Ratings at over 1000% are not recommended except for Powr-Rib(R) resistors. Curves for intermediate size resistors can be roughly estimated by comparison with the sizes given. Ratings for single pulses in the milli-second range (and up to 1 to 2 seconds) require individual calculation. This is because the ratings vary greatly with the resistance, or more specifically with the actual weight and specific heat of the resistance alloy used. Calculation is based on the assumption that all of the heat generated in the pulse goes to raise the temperature of the resistance wire. 1-866-9-OHMITE * Int'l 1-847-258-0300 * Fax 1-847-574-7522 * www.ohmite.com * info@ohmite.com Resistor Selection Application Notes P ulse O peration -- C ooling -- L imited T emperatures 100 70 50 40 30 Small Vitreous Enamel Resistors 10 watt 50 watt 125% 150% 100 70 50 40 30 200% 500% 20 1000% 10 7 5 4 3 500% 20 1000% 10 7 5 4 3 2 1 2 3 4 5 7 10 20 30 50 100 300 500 1K 40 70 200 400 700 2K 1 3K 5K 10K 4K 7K 1 2 3 4 5 7 10 "Off" Time in Seconds Large Vitreous Enamel Resistors 160 watt shown 1000% 10 7 5 4 3 2 Powr-ribs round wire edgewound 20 "On" Time in Seconds 500% 20 1 100 70 50 40 30 200% 100 70 50 40 30 3K 5K 10K 4K 7K Fig.12: Percent of Continuous Duty Rating for Pulse Operation of CORRIB(R), Corrugated Ribbon Resistors. 125% 150% 20 2K 200% 100 70 50 40 30 300% 500% 800% 1000% 20 10 7 5 4 3 2 3 4 5 7 10 30 50 100 300 500 1K 20 40 70 200 400 700 "Off" Time in Seconds 2K 3K 5K 10K 4K 7K Fig. 11: Percent of Continuous Duty Rating for Pulse Operation of Large Vitreous Enameled Resistors. 1 1 2 3 4 5 7 10 30 50 100 300 500 1K 20 40 70 200 400 700 "Off" Time in Seconds 2K 3K 5K 10K 4K 7K Fig. 13: Percent of Continuous Duty Rating for Pulse Operation of Powr-Rib(R), Bare Resistors 400 350 Percent Rated Watts Cooling Air Resistors can be operated at higher than rated wattage when cooled by forced circulation of air.

Actually there may be changes at full load of -4% to +8% of the initial resistance. The change is attributed in most part to the "temperature coefficient of resistance" (TCR) which is the change in resistance expressed as "parts per million per degree centigrade of temperature" (ppm/C). For special applications which require very constant resistance, it may be necessary to specify the maximum permissible TCR for the range of temperature involved. This would limit the choice of wire to only certain types of resistance alloys. The commonly known low TCR alloys in the 800 ohms per circular-mil-foot class consist largely of nickel and chromium alloyed with small amounts of aluminum and either copper or iron. Other low resistivity alloys, 294 ohms per circular-mil-foot, consist primarily of nickel and copper with only traces of other metals. +8% -50 0 +25 Temperature Attained, C +100 +200 90 ohms per C.M.F. wire +380 PPM/C +7% Calculated Change in Resistance +300 +6% +5% 675 ohms per C.M.F. wire +140 PPM/C +4% +3% +2% +1% Range for 294 or 800 ohms per C.M.F. wire 20 PPM/C 0 -1% -2% -3% -100 Both of these wire classes are rated by the wire manufacturers as having a TCR of 020ppm/C. The expression "020ppm/C" implies that, although the nominal value of the TCR is zero, the actual value may lie anywhere within the tolerance range of -20ppm/C to +20ppm/C. For other resistance wires such as the widely used nickelchromium-iron, for example, a nominal value of +140ppm/C is given. Actually, however, a tolerance of 30ppm is applicable so that the TCR may range between the limits of +110 to +170ppm/C. Unfortunately, the TCR of a completed power resistor is generally somewhat different from that of the original wire. This is because the TCR may be affected by such factors as heat treatment during processing, and materials and methods of construction. Without special controls and precautions, the TCR over the range of 25C to 300C rise may increase to as much as 080ppm from the original 020ppm for certain types of wire on vitreous enameled resistors. Theoretical changes in resistance with temperature are shown in Fig. 15. The circuit designer should carefully consider the actual needs of the circuit before specifying limits on the TCR of a desired resistor. Wherever possible it is best to select a resistor for a critical application so that it operates at a low temperature rise. This will also provide the maximum stability over a long period. For low TCR (and other) applications, Ohmite can provide resistors with an "Ohmicone" (silicone-ceramic) coating. "Ohmicone" is processed at much lower temperatures than vitreous enamel and therefore makes control of TCR and tolerance easier. Data on the TCR and other properties of various alloys is given on page 98.

The general use for each alloy is indicated by the column headed, "Resistance Range for Which Used." Whether a particular alloy can be used on a specific resistor can be estimated by dividing the given resistance by the area of the given winding space and determining whether the quotient falls within the limits given hereafter. The "high resistance" alloys cover the range from approximately 10 to 25,000 ohms per square inch of winding area, the "low to medium" type from 5 to 400 ohms and the "very low resistance" alloys from less than an ohm to 250 ohms. It should be noted that the "Ohms per Square Inch" ranges overlap considerably, indicating that in many instances a given resistor could use any of several alloys. Both the upper and lower limits of the ranges are only approximate and in general can be extended somewhat when necessary. The actual temperature coefficient of a complete resistor is generally greater than the nominal for the wire alone. The approximate change in overall resistance at full load is shown in the table.

These alloys have higher temperature coefficients, which limit their use to applications where the change in resistance with load is not important. An example is No. 60 alloy, which has a resistance of 60 ohms per circular-mil-foot and a temperature coefficient of +700ppm/C.

These are used for so-called "ballast" resistors where a large change in resistance is desired with a change in load. A typical ballast wire is Nickel, which has 58 ohms/cmf and a temperature coefficient of +4800ppm/C. Others are "Hytemco" and "Balco" at 120 ohms/CMF and a TC of +4500pp /C.
