High-Power Discharge Resistor from KOA

KOA now offers its proven BGRV, BWRV, and BSRV high-power series with full automotive certification. The wire-wound (BGRV, BWRV) and metal oxide-coated (BSRV) power resistors in ceramic housings are available with various terminal styles. The component is suitable for high switching currents as well as for use as a charging or discharge resistor. Power ratings between 3W and 40W are possible, with a resistance range from 1Ω to 75kΩ. Tolerances are 5% or 10%, and the components can be used at temperatures up to 155°C.

Potential applications include battery units, converter circuits, and on-board chargers in the field of e-mobility (HEV, EV), as well as converters/inverters in industrial applications. Naturally, BGRV, BWRV, and BSRV are tested according to AEC-Q200.
