Wide terminal resistors boost power ratings

KOA SPEER ELECTRONICS WK73R and WK73S Series Thick Film Wide Terminal Resistors are now 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). Devices provide a high power rating and improved shock resistance through their reverse geometry design. Products boost heat resistance with an operating temperature of -55°C to +155°C. Resistance values range from: WK73R1E from 10Ω to 1MΩ, WK73S2A from 100mΩ to 9.76Ω, WK73R2A from 10Ω to 1MΩ and WK73R2B from 10Ω to 9.76kΩ. All devices deliver high reliability and performance with a T.C.R. as low as ±100ppm°C, resistance tolerances of ±0.5%, ±1% and ±5%, and all are AEC-Q200 qualified.
