OverviewComposition, properties, and operation of the metal-oxide varistorHistoryApplicationsHazardsLimitationsComparison to other transient suppressorsMulti-layer varistor
The most common modern type of varistor is the metal-oxide varistor (MOV). This type contains a ceramic mass of zinc oxide (ZnO) grains, in a matrix of other metal oxides, such as small amounts of bismuth, cobalt, manganese oxides, sandwiched between two metal plates, which constitute the electrodes of the device. The boundary between each grain and a neighbor forms a diode junctio…

What is Varistor ?
When the applied voltage is below than the rated voltage, the varistor behaves as capacitor and stores charge carrier. Thus, the resistance of variable resistors shows nonlinear characteristics with the applied voltage.
How to Test a Varistor? (Easy Guide)
Is a varistor a capacitor? No, a varistor is not a capacitor. A varistor is a resistor that changes resistance with voltage. A capacitor stores energy in an electric field between two conducting plates. A varistor does not store energy; rather, it dissipates energy in the form of heat when there is a sudden increase in voltage (a voltage spike).
