Metal Oxide Varistor Code

They are composed primarily of z n o with small additions of other metal oxides such as bismuth cobalt magnese and others.

Metal oxide varistor code.

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. 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. A metal oxide varistor or mov protects sensitive electronic equipment from voltage spikes in the power line. This type contains a ceramic mass of zinc oxide 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.

The material is arranged between two metal plates or electrodes to interact with each other. Date hs code description origin country port of discharge unit quantity value inr per unit inr nov 22 2016. Mov s are the most used component to protect heavy devices. Mov 07d511k metal oxide varistor semi conductors devices.

The most common modern type of varistor is the metal oxide varistor mov. Mov is the most commonly used type of varistor. A gadget may have thousands of transistors resistors and other components but only one or two varistors. While it may look similar to a capacitor you can identify the device by its color markings and.

The boundary between each grain and a neighbor forms a diode junction which allows. 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.

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. Then followed by a date code yyww for year and week.
