Metal Oxid Varistors

Metal oxide varistors (MOV) are protective components whose resistance value depends on the voltage.

They are used because of their properties to protect against voltage peaks in electronic circuits.

Above a certain threshold, the resistance drops abruptly.

In varistors, who often work, it is useful, in addition to install a thermal fuse, as these are high impedance over time and can become hot, which may damage the device.
