Sintered ceramic bodies of various sizes can be obtained. Strict conditions of mixing, pressing, sintering and metallization ensure an excellent batch-to-batch product characteristics. This semi-conducting material reacts as an NTC resistor, whose resistance decreases with increasing temperature. This Negative Temperature Coefficient effect can result from an external change of the ambient temperature or an internal heating due to the Joule effect of a current flowing through the thermistor. By varying the composition and the size of the thermistors, a wide range of resistance values (0.1 to 1M) and temperature coefficients (-2 to -6% per C) can be achieved. RoHS (Restriction of Hazardous Substances - European Union directive 2002/95/EC). ELV (End of Life-Vehicle - European Union directive 2000/53/EC). All Thermistor Products have been fully RoHS/ELV since before 2006. Chip Thermistor NB RoHS/ELV Status: external Plating 100% smooth semi-bright Sn as standard SnPb Termination available on request. 2 - MAIN CHARACTERISTICS The nominal resistance of an NTC thermistor is generally given at 25C. It has to be measured at near zero power so that the resultant heating only produces a negligible measurement error. The following table gives the maximum advised measurement voltage as a function of resistance values and thermal dissipation factors. This voltage is such that the heating effect generated by the measurement current only causes a resistance change of 1% Rn/Rn. R 10 10 < R 100 100 < R 1,000 1,000 < R 10,000 10,000 < R 100,000 R < 100,000 2 Maximum measuring voltage (V) = 2 mW/C = 5 mW/C = 10 mW/C = 20 mW/C 0.25 0.73 2.1 6.4 0.13 0.38 1.1 3.2 9.7 0.18 0.53 1.5 4.6 14.5 This is the relation between the zero power resistance and the temperature. It can be determined by experimental measurements and may be described by the ratios R (T) /R (25C) where: R (T) is the resistance at any temperature T R (25C) is the resistance at 25C. These ratios are displayed on pages 29 to 33. 2.1.3. Temperature coefficient () The temperature coefficient () which is the slope of the curve at a given point is defined by: = 100 dR * R dT and expressed in % per C. 2.1.4. Sensitivity index (B) The equation R = A exp (B/T) may be used as a rough approximation of the characteristic R (T). B is called the sensitivity index or constant of the material used. To calculate the B value, it is necessary to know the resistances R1 and R2 of the thermistor at the temperatures T1 and T2. 1 1 The equation: R1 = R2 exp B T - T 1 2 R1 1 leads to: B (K) = * n 1-1 R2 T1 T2 Conventionally, B will be most often calculated for temperatures T1 = 25C and T2 = 85C (298.16 K and 358.16 K). In fact, as the equation R = A exp (B/T) is an approximation, the value of B depends on the temperatures T1 and T2 by which it is calculated. For example, from the R (T) characteristic of material M (values given on page 29), it can be calculated: B (25 - 85) = 3950 B (0 - 60) = 3901 B (50 - 110) = 3983 When using the equation R = A exp (B/T) for this material, the error can vary by as much as 9% at 25C, 0.6% at 55C and 1.6% at 125C. Using the same equation, it is possible to relate the values of the index B and the coefficient : ( ( 2.1 CHARACTERISTICS WITH NO DISSIPATION 2.1.1. Nominal Resistance (Rn) Ranges of values () 2.1.2. Temperature Resistance characteristics R (T) 0.10 0.24 0.24 2.0 = ) ) ( ) 1 -B 1 dR = * * A exp (B/T) * T2 A exp (B/T) R dT B thus = - T2 expressed in %/C NTC Thermistors General Characteristics 2.1.5. Further approximation of R (T) curve The description of the characteristic R (T) can be improved by using a greater number of experimental points, and by using the equation: 1 = A + B (n R) + C (n R)3 T The parameters A, B and C are determined by solving the set of equations obtained by using the measured resistances at three temperatures. The solution of the above equation gives the resistance at any temperature: [ ( ) ( ( ) ( ) ) - 3+ 27 (A- 1/T) + 3 3(27(A- 1/T) + 4 (B) )] C 2 2 C C n R (T) = 1 3 27 A- 1/T 3 3 27 A- 1/T 2+ 4 B + 3 C C C 2 2 2 Thus, the tolerance on the resistance (R2/R2) at a temperature T2 is the sum of two contributions as illustrated on Figure 1: - the tolerance R1/R1 at a temperature T1 used as a reference. - an additional contribution due to the dispersion on the characteristic R (T) which may be called "Manufacturing tolerance" (Tf). Graph with B R Graph with B B 3 }(R) R 25 25C 3 } (R) + The precision of this description is typically 0.2C for the range -50 to +150C (A, B, C being determined with experimental values at -20, +50 and 120C) or even better if this temperature range is reduced. The ratios R(T)/R(25C) for each of the different materials shown on pages 29 to 33 have been calculated using the above method. } 25C T 2.1.6. Resistance tolerance and temperature precision An important characteristic of a thermistor is the tolerance on the resistance value at a given temperature. This uncertainty on the resistance (DR/R) may be related to the corresponding uncertainty on the temperature (DT), using the relationship: R 1 T = 100 * R * Example: consider the thermistor ND06M00152J -- * R (25C) = 1500 ohms * Made from M material * R (T) characteristic shown on page 23 gives: = - 4.4%/C at 25C * Tolerance R/R = 5% is equivalent to: T = 5%/4.4%/C = 1.14C 2.1.7. Resistance tolerance at any temperature Any material used for NTC manufacturing always displays a dispersion for the R (T) characteristic. This dispersion depends on the type of material used and has been especially reduced for our accuracy series thermistors. 25C TF } = (R) T Temperature (C) Figure 1 Differentiating the equation R = A exp (B/T), the two contributions on the tolerance at T can also be written: R2 = R1 + 1 - 1 * B T1 T2 R1 R2 The T(f) values given with the resistance - temperature characteristics on pages 29 to 33 are based on a computer simulation using this equation and experimental values. 2.1.8. Designing the resistance tolerances Using the fact that the coefficient decreases with temperature ( = -B/T2), it is generally useful to define the closest tolerance of the thermistor at the maximum value of the temperature range where an accuracy in C is required. For example, let us compare the two designs 1 and 2 hereafter: T R (C) () 0 25 55 85 100 3275 1000 300 109 69.4 Design 1 (%/C) R/R(%) -5.2 -4.4 -3.7 -3.1 -2.9 3.5 3.0 3.5 4.1 4.5 Design 2 T(C) R/R(%) 0.7 0.7 1.0 1.3 1.6 5.0 4.5 4.0 3.4 3.0 T(C) 1.0 1.1 1.1 1.1 1.0 Only the Design 2 is able to meet the requirement T 1C from 25C to 100C. 3 NTC Thermistors General Characteristics 2.1.9. Shaping of the R (T) characteristic By the use of a resistor network, it is possible to modify the R (T) characteristic of a thermistor so that it matches the required form, for example a linear response over a restricted temperature range. A single fixed resistor Rp placed in parallel with a thermistor gives a S-shape resistance-temperature curve (see Figure 2) which is substantially more linear at the temperature range around the inflexion point (Ro, To). R (k) RTO 2.2 CHARACTERISTICS WITH ENERGY DISSIPATION When a current is flowing through an NTC thermistor, the power due to the Joule effect raises the temperature of the NTC above ambient. The thermistor reaches a state of equilibrium when the power supplied becomes equal to the power dissipated in the environment. The thermal behavior of the thermistor is mainly dependent on the size, shape and mounting conditions. Several parameters have been defined to characterize these properties: 2.2.1. Heat capacity (H) Rp The heat capacity is the amount of heat required to change the temperature of the thermistor by 1C and is expressed in J/C. Rp 2.2.2. Dissipation factor () This is the ratio between the variation in dissipated power and the variation of temperature of the NTC. It is expressed in mW/C and may be measured as: U.I = 85 - 25 RO TO T (C) Figure 2 - Linearization of a thermistor where U.I is the power necessary to raise to 85C the temperature of a thermistor maintained in still air at 25C. 2.2.3. Maximum permissible temperature (T max) It can be calculated that better linearization is obtained when the fixed resistor value and the mid-range temperature are related by the formula: B - To Rp = R x To B+ 2To This is the maximum ambient temperature at which the thermistor may be operated with zero dissipation. Above this temperature, the stability of the resistance and the leads attachment can no longer be guaranteed. For example, with a thermistor ND03N00103J -- R 25C = 10k, B = 4080 K good linearization is obtained with a resistor in parallel where the value is: 4080 - 298 Rp = 10,000 x = 8088 4080 + (2 x 298) This is the power required by a thermistor maintained in still air at 25C to reach the maximum temperature for which it is specified. For higher ambient temperatures, the maximum permissible power is generally derated according to the Figure 3 hereafter and TL = Tmax - 10C. 2.1.10. Demonstration of the R (T) parameters calculation 2.2.4. Maximum permissible power at 25C (Pmax) P max To help our customers when designing thermistors for temperature measurement or temperature compensation, software developed by our engineering department is available upon request. 25 TL T max Figure 3 - Derating of maximum power 4 TC NTC Thermistors General Characteristics 2.2.5. Voltage - Current curves V (l) 2.2.7. Thermal time constant These curves describe the behavior of the voltage drop V measured across the NTC as the current l through the NTC is increased. They describe the state of equilibrium between power resulting from Joule effect and dissipated power in the surroundings. (Figure 4) When a thermistor is self-heated to a temperature T above ambient temperature Tamb, and allowed to cool under zero power resistance, this will show a transient situation. At any time interval dt, dissipation of the thermistor ((T - Tamb)dt) generates a temperature decrease -HdT, resulting in the equation: 1 dT = dt (T - Tamb) H The solution to this equation for any value of t, measured from t = 0, is: (T - Tamb) = - t n (To - Tamb) H V Vmax Io I Figure 4 - Voltage - current curve V (l) Several zones can be identified: - low current zone dissipated energy only produces negligible heating and the curve V (l) is almost linear. - non-linear zone the curve V (l) displays a maximum voltage Vmax for a current lo.This maximum voltage Vmax and the temperature Tmax reached by the NTC under these conditions can be determined by using the equations: and P = V2/R = (T - Tamb) R = Ramb * exp B (1/T - 1/Tamb) therefore: 1+Tamb Tmax = B/2 - B2/4 - BTamb ~ Tamb B Vmax = ( ) 1 - 1 (Tmax - Tamb ) * Ramb exp [B(Tmax Tamb)] where is the dissipation factor and Tamb is the ambient temperature. - high current zone for higher currents, an increase in temperature of the NTC decreases the resistance and the voltage more rapidly than the increase of the current. Above a certain dissipated power, the temperature of the NTC exceeds the permissible value. We can define a thermal time constant as: = H/ expressed in seconds. Where the time t = : (T - Tamb) / (To - Tamb) = exp - 1 = 0.368 expressing that for t = , the thermistor cools to 63.2% of the temperature difference between the initial To and Tamb (see Figure 5). According to IEC 539 our technical data indicates measured with To = 85C, Tamb = 25C and consequently T = 47.1C. T (C) 85 47.1 25 t t (s) Figure 5 - Temperature - time curve T(t) 2.2.8. Response time More generally, it is possible to define a response time as the time the thermistor needs to reach 63.2% of the total temperature difference when submitted to a change in the thermal equilibrium (for example from 60C to 25C in silicone oil 47V20 Rhodorsil). 2.2.6. Current - Time curves l(t) When voltage is applied to a thermistor, a certain amount of time is necessary to reach the state of equilibrium described by the V(l) curves. This is the heating up time of the thermistor which depends on the voltage and the resistance on one side and the heat capacity and dissipation on the other. The curves l(t) are of particular interest in timing applications. 5 NTC Thermistors Application Notes TEMPERATURE MEASUREMENT Thermistor circuit High sensitivity and low cost make NTC thermistors the most common device used for temperature measurement. Non-linearity of the R -T curve generally leads to the use of a resistor network to linearize the signal. An example is given in Figure 6. More precise measurements and temperature display can also be achieved with simple electronic equipment as shown in Figure 7. The choice of the model will particularly take into account the small size (better response time) and the resistance tolerance. Mounting conditions (dissipation), and input voltage (self-heating) will also be carefully defined to avoid serious errors in temperature measurement. TEMPERATURE CONTROL AND ALARM R2 R3 A/D converter R1 processor with R/T R NTC algorithm Display TC Figure 6 Figure 7 NTC thermistors can be used as a simple on-off control temperature system or temperature alarm system. Figure 8 gives an example of such a circuit. When the temperature increases to a defined value, the resistance of the thermistor decreases and the current becomes sufficiently high to energize the relay and provide temperature alarm or heating system turn-off. The high sensitivity of thermistors (about 4% resistance change for 1C) allows the temperature to be controlled very precisely. R1 R3 R2 R NTC Figure 8 TEMPERATURE COMPENSATION As many electronic components (integrated circuits, amplifiers,...) have a positive temperature coefficient of resistance, NTC thermistors represent a cheap and interesting solution to compensate for this effect and provide an improved temperature stability for electronic equipment. It is necessary to include the thermistor in a resistor network (Figure 10) calculated in such a manner that the network coefficient compensates exactly for the positive temperature coefficient of the other component (Figure 9). Common leaded discs or chip thermistors are well suited for this application. Resistance RC R Total RC R R NTC R R NTC Temperature Figure 9 6 Figure 10 NTC Thermistors Application Notes RS LIQUID LEVEL OR FLOW DETECTION The dissipation of a thermistor is significantly different in a liquid or in a gas, in a static fluid or in a stirred one. A liquid level detector or a gas-flow measurement can be designed using this property. In Figure 11, the output voltage measured on the thermistor depends upon the dissipation factor of its environment, and can be illustrated by V-l curves (Figure 12). This voltage can be used to detect the presence (V2) or absence (V1) of liquid around the thermistor or measure the flow speed. A good design should define a precise operating temperature range, where dissipation in the high dissipating medium at highest ambient temperature remains higher than the dissipation in low dissipating medium at lowest ambient temperature. R NTC V V in Figure 11 Voltage V in V2 V1 k2 k1 SURGE PROTECTION A soft start of sensitive apparatus can be achieved by using NTC thermistors as described in Figures 13 and 14. At turn-on, the NTC absorbs the surge current, limits the current across the equipment and protects it. Then, the thermistor heats, its resistance decreases and most of the power becomes applied to the apparatus. In its design, the thermistor will be selected with a thermal capacity higher than the surge energy to absorb. V in/RS Figure 12 R NTC Equipment Figure 13 TIME DELAY The current-time characteristic of a thermistor is used in time delay applications such as delaying energization of a relay after application of power to an electrical circuit. The time delay, time necessary for the thermistor to heat up to the temperature where its resistance allows the current to reach the switching value of the relay, is mainly defined with the nominal resistance of the thermistor. The time delay is also strongly dependent upon the ambient temperature, as shown in Figure 15.

Natural Cooling 250 1 to 2 min 3 sec. max (Preheat chips before soldering) T/maximum 150C a) The visual standards used for evaluation of solder joints will need to be modified as lead free joints are not as bright as with tin-lead pastes and the fillet may not be as large. b) Resin color may darken slightly due to the increase in temperature required for the new pastes. c) Lead-free solder pastes do not allow the same self alignment as lead containing systems. Standard mounting pads are acceptable, but machine set up may need to be modified.

They are assembled in custom-probes for sensing the temperature of liquids (water, oil, ...), gases or surface of any other component. The metallization covers completely the surfaces of the thermistor. The particularly flat and smooth surfaces ensure an excellent electrical and thermal contact under pressure.

Values and tolerances DESIGN OF THE THERMISTOR Choice of the resistances Choice of the tolerances If the application is to measure the temperature around a defined point, a unique nominal resistance can be chosen (for example, among standard values of the ND range products presented on pages 20 to 24). When it is required to measure the temperature over selected ranges T1 -T2 , T2 -T3 , ..., the corresponding resistance R1 , R2 , R3 , ..., must be such that they can be located on the R (T) characteristic of an existing NTC material (for example among standard materials whose R (T) are displayed on pages 29 to 33). The resistances must also be compatible with the resistivity of the material and the dimensions of the thermistor. The precision of the temperature measurement determines the calculation of the tolerance on the resistance: R/R = (%/C). T (C) For example, the NTC NR55--3049-99, using "N5" material (R (T) characteristic displayed on page 31), requires a precision of 1C over the temperature range 110C - 120C. The tolerances can be calculated: R110C /R110C = 1C* 2.91%/C = 2.91% R120C /R120C = 1C* 2.76%/C = 2.76% *For your specific requirements, please consult us.
