Anti-Surge Resistors


Tokenchina's Anti-Surge Resistor is a perfect fit when electronic products have to be surge immune to ensure their continued reliable operation if subjected to realistic levels of surge voltages, and they are required to comply with safety requirements.

Tokenchina full line products meet RoHS compliant and extend a complete line for both military and commercial applications.

Tokenchina RCR series is equated to Vishay Anti-Surge VR series. Please contact our sales for more information.
