  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. are mostly varistors with zinc oxide as the main material. MOV is a kind of polycrystalline semiconductor ceramic device which is mainly made of zinc oxide and doped with various metal oxides through the typical electronic ceramic process. The product structure is as shown in (Figure 2). Products with different temperature resistance and different functions are made of different materials ...

  3. The Littelfuse varistor is composed primarily of zinc oxide with small additions of bismuth, cobalt, manganese and other metal oxides. The structure of the body consists of a matrix of conductive zinc oxide grains separated by grain boundaries which provide P-N junction semiconductor characteristics.
