High Power Resistors

Wide range of resistance values in the product lineup is available for high power range

Application example

BGRV/BWRV/BSRV：Pre-charge resistor for xEV, discharge resistor (Passive and Active)

HPC/PCF: Power supplies, rapid discharge resistors for xEVs

Structural Differences Between Cement and Ceramic Resistors

Cement resistors(BGRV/BWRV/BSRV)

Ceramic resistors(HPC/PCF)

■If the pulse is continuous, cement resistors with high power rating are suitable
■Low resistance tolerance/stable circuit operation than low TCR
■ Possibility of adversely affecting other circuits is low because of open failure in case of overload
■ Excellent insulation and flame retardancy due to ceramic outer coating

■ If the pulse is not continuous, ceramic resistors that can be miniaturized are suitable
■Small size and lightweight
■Smaller than cement resistors and more pulse resistant
■Wide resistance range
■High resistance to environmental conditions　
■Non-inductive
