High Frequency Non-inductive Ceramic Voltage Resistors


Tokenchina's high frequency ceramic RY31A of high voltage series is rugged to sustain the very high peak power and current inputs generated by capacitor banks, pulse generator systems, and steady state current loads.

RY31A resistor is produced by depositing a metal oxide element on a high-grade ceramic body and coated with a lacquer, which provides electrical, mechanical and climatic protection. High Frequency RY31A Resistors features higher thermal resistance and larger electric power capacity for the compact volume.

RY31A ceramic resistor meets RoHS compliant. Detailed specifications, both mechanical and electrical, please contact our sales representative for more information.
