Zinc Oxide Varistors General Metal Oxide Varistors are ceramic passive components made of zinc oxide sintered together with other metal oxide additives. They provide an excellent protective device for limiting surge voltages and absorbing energy pulses. Their very good price / performance ratio enables designers to optimize the transient protection function when designing the circuits. Varistors are Voltage Dependent Resistors whose resistance decreases drastically when voltage is increased. When connected in parallel with the equipment to protect, they divert the transients and avoid any further overvoltage on the equipment. Manufactured according to high level standards of quality and service, our Metal Oxide Varistors are widely used as protective devices in the telecommunications, industrial, automotive and consumer markets. 2
