Metal oxide varistor – Described above, the MOV is a nonlinear transient suppressor composed of zinc oxide (ZnO) Silicon carbide varistor – At one time this was the most common type before the MOV came into the market. These components utilize silicon carbide (SiC). They have been intensively used in high power, high voltage applications.
Mar 22, 2024 · The operation of metal oxide varistor and silicon carbide varistor are very similar. A metal oxide varistor starts conducting current at rated voltage and it stops the conduction if the applied voltage is below the threshold value. The main difference between a silicon carbide varistor and a metal oxide varistor is the amount of leakage current.
A metal oxide varistor is a voltage-dependent resistor. A metallic oxide varistor is around 90% Zinc oxide and 10% other metallic oxides. Typical metal oxide varistors get made with ceramic powers, such as zinc oxide grains.

Jun 13, 2021 · The Metal Oxide Varistor is a voltage-dependent resistor made of metal oxides ceramic powders such as zinc oxide and some of the other metal oxides such as cobalt oxides, manganese, bismuth, etc. A MOV consists of around 90% zinc oxide and a limited quantity of other metal oxides. Between two metal plates known as the electrodes, the ceramic ...
The metal oxide varistor, with its extremely attractive price/ performance ratio, is an ideal component for limiting surge voltage and current as well as for ab-sorbing energy. The EPCOS product range includes radial-leaded disks, block varistors and strap varistors for power distribution applications. Special types for automotive electrical ...
Mar 11, 2019 · Completely up-to-date, this is the first comprehensive monograph on metal oxide varistors with a focus on microstructure, conduction mechanisms, device failures, ageing, additive impacts and future varistor systems. As such, it covers the fundamentals and applications of metal oxide varistors, including their macro-characteristics, microstructural properties and the device-internal physical ...
A varistor that is made with a combination of zinc oxide & other kinds of metal oxides such as manganese, cobalt, etc is known as metal oxide varistor. The material is arranged between two metal plates or electrodes to interact with each other. These types of varistors protect from heavy devices from transient voltages. Metal Oxide Varistor
