The WK732B offers a higher power rating and features high reliability and performance with 0.75W power rating as a result of its enhanced heat dissipation, compared to the standard 0.25W of thick film 1206 size.
Featuring a wide terminal construction, the WK732B resistor provides superior thermal shock characteristics as well as high sollder joint reliability. The WK73S2B offers a resistance range of 10mΩ ~ 9.1Ω, while the WK73R2B offers 10Ω ~ 1MΩ. Other performace characteristics include tolerances of 1% and 5% and TCR values of ±100 ~ ±800 ppm/oC. The WK732B is AEC-Q200 qualified.
The WK732B series offers current sensing for power supply circuits, and is ideal for automotive electronics, ECUs, anti-lock braking and air bag systems.
