PMR Series

Overview

A special alloy is utilized for the resistive element, enabling ultra-low resistance (1m to 10m) and low TCR in a compact form factor.
In addition, proprietary construction ensures a higher rated voltage than conventional chip resistors.
Contributes to greater compactness and performance in module devices for current control.
