Metal Oxide Varistor has the advantage 1)Fast response to the rapidly rising surge voltage. 2)Excelllent non-linearity voltage

Metal Oxide Varistor is non-linear resistor utilizing as semiconductor electrocnic ceramic element mainly composed of zinc oxide and its resistance change as a function of applied voltage.It's called varistor or mental oxide varistor, just as it is sensitive to voltage's change.
