KOA Speer Introduces New Power Ratings/Sizes to WK73 Series Wide Terminal Resistors

KOA Speer | Thick Film ResistorBradford, PA - October 25, 2018 - KOA Speer Electronics is expanding the WK73R and WK73S Series Thick Film Wide Terminal Resistors with several new power ratings and package sizes. These wide 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). KOA Speer's wide terminal thick film chip resistors provide a high power rating and improved shock resistance through their reverse geometry design. In addition, these resistors offer superior heat resistance with an operating temperature of -55°C to +155°C.

Resistance values for these new resistors are as follows: WK73R1E from 10Ω to 1MΩ, WK73S2A from 100mΩ to 9.76Ω , WK73R2A from 10Ω to 1MΩ and WK73R2B from 10Ω to 9.76kΩ. All of these resistors 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.

KOA Speer’s new wide terminal thick film resistors are an excellent choice for use in automotive power supplies (DC-DC conversion), ECU, motor controls and industrial power supplies.

Lead time is 10 weeks for these resistors. Please contact KOA Speer Electronics for samples or additional information.
