Protection Component

An electronic device with significantly non-ohmic conducting properties, in which the resistance values vary with the external voltage, so that its current-voltage characteristic curve is significantly non-linear.

Varistors are widely used in electronic circuits to protect against potential circuit damage caused by transient voltage surges in power supply systems.

When a high voltage is applied, the resistance of the varistor decreases and diverts the current, thus protecting sensitive electronic components
