Metal oxide varistor code.

A gadget may have thousands of transistors resistors and other components but only one or two varistors. They are composed primarily of z n o with small additions of other metal oxides such as bismuth cobalt magnese and others. Mov is the most commonly used type of varistor. 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 boundary between each grain and a neighbor forms a diode junction which allows. Metal oxide variators mov or now generically referred to as siov s are commonly rated by their rms withstanding voltage or 385vac in this case then above this by a joule rating 05 which seems low. Metal oxide varistors consist of approximately 90 zinc oxide as a ceramic base material plus other filler materials for the formation of junctions. Metal oxide varistors and multi layered varistors.

Varistors are voltage dependent nonlinear devices which have electrical characteristics similar to back to back zener diodes. The most common modern type of varistor is the metal oxide varistor mov. Mov s are the most used component to protect heavy devices. Date hs code description origin country port of discharge unit quantity value inr per unit inr nov 22 2016.

Metal oxide varistor basics. Mov 07d511k metal oxide varistor semi conductors devices. The material is arranged between two metal plates or electrodes to interact with each other. While it may look similar to a capacitor you can identify the device by its color markings and.

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. 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.
