KOA Speer Electronics (Bradford, PA) has released a new size for the WK73 wide terminal flat chip resistor series, the 2B (0612) package. The WK732B 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 the thick film 1206 size.

With a wide terminal construction, the WK732B resistor features:

  • Superior thermal shock characteristics.
  • High solder joint reliability.
  • Resistance range of 10m - 9.1Ω (WK73S2B) and 10 – 1MΩ (WK73R2B).
  • Tolerance of 1% and 5%.
  • TCR values of ±100 – ±800 ppm/°C.
  • AEC-Q200 qualified.

The WK732B offers current sensing for power supply circuits, and is ideal for automotive electronics, ECUs, anti-lock braking, and air bag systems.
