Bradford, PA – October 26, 2017 – KOA Speer Electronics introduces its new WK73R1J Thick Film Wide Terminal Resistors featuring a 0.5 watt power rating in a 0306 package. The WK73R1J is a thick film chip resistor that is able to achieve a high power rating of 0.5 watts due to its reverse geometry design, which provides for greater heat dissipation. In addition, this resistor offers superior thermal shock characteristics and solder joint resistance, and excellent overall heat resistance with an operating temperature of -55°C to +155°C. The higher power rating of the 0306 size WK73R1J accommodates an engineer's desire for downsizing to allow for more available board space.
KOA Speer’s WK73R1J resistor delivers high reliability with its low T.C.R. of ±100 ppm/°C with resistance tolerance of 1% and 5%.
The WK73R1J will be offered in resistance values of 10Ω to 1MΩ and is AEC-Q200 qualified.The WK73R1J is an excellent choice for use in automotive power supplies (DC-DC conversion), ECU and industrial power supplies.
Lead time is 10 weeks for WK73R1J resistors. Samples are available upon request.
