220pF 430V Through-Hole Varistor is a Metal Oxide varistor. A Metal Oxide Varistor (MOV) or a Zinc Oxide Varistor (ZOV) is a component used in electrical and electrical circuits where the voltage has to be restricted. They are mainly used in the protective circuits of voltage-sensitive electronic devices. A Varistor ensures that all transient surge voltages are effectively bypassed and do not reach the device.
The Varistor is designed to carry excessive currents whenever there is a surge in voltage. A Varistor uses metal oxide in its construction and its resistance varies non-linearly with voltage.
