Varistor Market: Global Suppliers, Chinese Manufacturers, and 2026 Industry Guide

1. Introduction to Varistor

A varistor, also known as a Voltage Dependent Resistor (VDR), is an electronic component with a non-ohmic current-voltage characteristic. Its primary function is to protect circuits from excessive transient voltages by clamping the voltage to a safe level. When a high voltage surge occurs, the varistor’s resistance drops dramatically, shunting the surge current away from sensitive components. The most common type is the Metal Oxide Varistor (MOV), typically made from zinc oxide (ZnO) with small amounts of other metal oxides. Varistors are widely used in power supplies, telecommunications, industrial equipment, and consumer electronics to ensure reliability and safety.
