210 Series Dividohm(R) Vitreous Enamel Adjustable Power F e at u r e s * Terminals suitable for soldering or bolt connection. * Adjustable lug supplied * High wattage applications * All-welded construction * Rugged lead free vitreous enamel coating. * Flame resistant coating * Additional adjustable lugs available * RoHS compliant product available. Add "E" suffix to part number to specify Choose Ohmite's 210 Type adjustable resistors for applications requiring settings at different resistance values. These wirewound resistors are equipped with an adjustable lug, making them ideal for adjusting circuits, obtaining odd resistance values and setting equip ment to meet various line voltages. 210 Type resistors feature a hollow core to permit secure fastening with spring-type clips or thru bolts with washers. They also offer the durability of lead free vitreous enamel coating and all-welded construction. Mounting brackets not included with resistors.

Coating Lead free vitreous enamel. Large models (500 watts and up) are supplied in Silicone Ceramic. Also available in low-cost Centohm coating; Consult factory. Core Tubular ceramic. Terminals Solder coated radial lug. RoHS solder composition is 96% Sn, 3.5% Ag, 0.5% Cu Adjustable Nickel plated steel. (Screwdriver type adjustable lug supplied terminal standard. Other types, including silver contact units, available.) Derating Linearly from 100% @ +25C to 0% @ +350C. Tolerance 10% (K) Power rating Based on 25C free air rating. The stated wattage rating applies only when the entire resistance is in the circuit. Setting the lug at an intermediate point reduces the wattage rating by approximately the same proportion. Example: If the lug is set at half resistance, the wattage is reduced by approx. one-half. Overload 10 times rated wattage for 5 seconds. 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 109 35,000 50,000 210 Series Dividohm(R) Vitreous Enamel Adjustable Power d i m e ns i ons (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 nfo r m a t i on 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 = Standard values; check availability at www.ohmite.com 110 ---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 D50K--- 50 D25K--- 25 150 200 250 300 400 500 750 800 1,000 1,250 1,500 2,000 2,500 D12K--- 12 Ohmic value D500K--- 500 D225K--- 225 D175K--- 175 D100K--- 100 75 D75K--- 50 25 D25K--- D50K--- 12 D12K--- 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 Mouser Electronics Authorized Distributor Click to View Pricing, Inventory, Delivery & Lifecycle Information: Ohmite: D175K15K D12K50R D12K15R D12K10R D25K400 D12K500 D75K400 D25K750 D75K750 D12K7K5 D75K7K5 D50K7K5 D25K7K5 D25K5R0 D75K2K25 D50K50K D50K60K D100K25R D100K10R D100K50R D100K1K5 D100K5R0 D100K500 D75K80K D225K25K D225K20K D175K25K D175K20K D100K50K D12K8K5 D225K2K5 D50K20K D50K25K D225K1K5 D12K400 D175K25R D225K15K D175K10K D225K10K D50K500 D50K5R0 D175K1R0 D175K2R0 D175K4R0 D175K3R0 D12K600 D25K150 D225K25R D225K50R D225K10R D12K750 D50K750 D50K1R0 D50K150 D50K100 D12K20R D12K25R D100K5K0 D175K2K5 D100K1K0 D12K75R D50K40K D50K10K D50K2K0 D50K12K D50K8K0 D50K6K0 D50K3K0 D50K4K0 D12K1K25 D75K4K5 D12K800 D25K4K5 D50K4K5 D12K4K5 D50K9K0 D50K15K D50K5K0 D50K7K0 D50K1K0 D225K5K0 D225K1K0 D50K4R0 D75K200 D25K2R0 D25K200 D12K3R0 D75K250 D25K250 D12K300 D225K3R0 D12K350 D12K10K D12K7R5 D12K1K5 D50K1K5 D75K1K5 D75K45K D75K40K D75K15R
