New Rectangular Power Type Resistors for Automotive from KOA

Automotive Grade Pre-Charge / Discharge Resistors
High Power Ceramic Cased Resistors

BGRV wirewound resistors – designed to withstand the high inrush currents present in Electric Vehicle pre-charge circuits.
BWRV wirewound resistors – features lower resistance values as well as improved T.C.R. and tight resistance tolerances.
BSRV metal oxide resistors – designed for the capacitor discharge function in the DC/DC converter and in Electric Vehicle discharge circuits.

All 3 resistor series are available with spade/lug terminals for use in wiring harness or connector blocks.
