Zinc Oxide Varistors are semiconductor electronic ceramic components primarily composed of zinc oxide. Their resistance values change non-linearly with applied voltage. Due to the high sensitivity of resistance to voltage variation, they are known as varistors or surge absorbers. Zinc Oxide Varistor are non-linear resistors utilizing semiconductor electronic ceramic element mainly composed of zinc oxide and its non-linear resistance change as a function of the applied voltage. It's called Varistor or Surge absorbers.
