Terminal Resistor Family Extends Sizes & Power Ratings

KOA Speer Electronics has expanded the WK73R and WK73S Series Thick Film Wide Terminal Resistors with several power ratings and package sizes. The terminal resistors will now be available in WK73R1E (0204 size, 0.33 Watt), WK73S2A (0508 size, 1 Watt), WK73R2A (0508 size, 0.75Watt & 1 Watt) and WK73R2B (0612 size, 1 Watt).


The higher power ratings and improved shock resistance are the result of the company’s reverse geometry design. In addition, these resistors offer reliable heat resistance with an operating temperature of -55°C to +155°C. Resistance values are: WK73R1E from 10Ω to 1 MΩ, WK73S2A from 100 mΩ to 9.76Ω , WK73R2A from 10Ω to 1 MΩ and WK73R2B from 10Ω to 9.76 kΩ. All deliver a TCR. as low as ±100 ppm°C, resistance tolerances of ±0.5%, ±1% and ±5%, and all are AEC-Q200 qualified. For more details, visit KOA Speer and/or call 814-362-5536.
