  1. Dec 9, 2019 · Metal Oxide Varistor is a voltage-dependent resistor that is made with ceramic powders of metal oxides like Zinc oxide and some of the other metal oxides like oxides of cobalt, manganese, bismuth, etc. A MOV consist of approximately 90% of Zinc oxide and a small amount of other metal oxides.

  2. The Metal Oxide Varistor or MOV for short, is a voltage dependant resistor in which the resistance material is a metallic oxide, primarily zinc oxide (ZnO) pressed into a ceramic like material. Metal oxide varistors consist of approximately 90% zinc oxide as a ceramic base material plus other filler materials for the formation of junctions ...

    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.

  4. Metal Oxide Varistor – Basics. MOV is the most commonly used type of varistor. It is called so as the component is made from a mixture of zinc oxide and other metal oxides like cobalt, manganese and so on and is kept intact between two electrodes which are basically metal plates.

  5. Dec 12, 2018 · A Metal Oxide Varistor (MOV) is a protection component used in power supply circuits that is powered directly from AC mains. It is used to protect the circuit from high voltage spikes by varying its resistance.

  6. Surface mountable MOV (Metal Oxide Varistor) devices facilitate customs in SMT assembly process and resolve the PCB space limitation issue. They are reflow and wave solderable and include the CH, SM7, SM20, MLE, MHS, ML, and MLN series.

  7. Feb 28, 2010 · The Metal Oxide Varistor or MOV is a voltage dependent, nonlinear device that provides excellent transient voltage suppression. The Metal Oxide is designed to protect various types of electronic devices and semiconductor elements from switching and induced lightning surges.
