✅ Product Description

Overview

Metal Oxide Varistors (MOVs) are essential protection components used to safeguard electronic circuits from voltage surges and transient spikes. When abnormal high voltage appears on a line, the varistor instantly clamps the voltage to a safe level, absorbing excess energy and preventing damage to sensitive components.

These varistors are commonly used in power supplies, household appliances, chargers, LED drivers, control panels, and various electronic designs. Each variant offers a specific clamping voltage and disc size to match different circuit requirements.
