IsoMOV™ Hybrid Protection Components

Bourns IsoMOV™ Hybrid Protection Components are hybrid technology varistors. These varistors combine the surge performance of EdgMOV™ protection devices with an integrated Gas Discharge Tube (GDT) isolation structure to create an innovative IsoMOV hybrid protection component. With the combination of these features, the IsoMOV series achieves high performance as a long-life protector with lower capacitance, low leakage, and state-of-the-art energy handling density.
