    Metal Oxide Varistors Overview and Supply Chain
    A Metal Oxide Varistor (MOV) production line creates voltage-dependent resistors, primarily using zinc oxide (ZnO) and additives like bismuth, cobalt, and manganese. The process involves mixing, granulation, molding, high-temperature sintering, electrode application, coating, and 100% testing.

    What is another name for a varistor?
    voltage-dependent resistor
    A varistor (a.k.a. voltage-dependent resistor (VDR)) is a surge protecting electronic component with an electrical resistance that varies with the applied voltage. It has a nonlinear, non-ohmic current–voltage characteristic that is similar to that of a diode.
