Metal Oxide Varistor Code

The most common modern type of varistor is the metal oxide varistor mov.

Metal oxide varistor code.

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. Date hs code description origin country port of discharge unit quantity value inr per unit inr nov 22 2016. 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. 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 material is arranged between two metal plates or electrodes to interact with each other. 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. Metal oxide varistors and multi layered varistors. While it may look similar to a capacitor you can identify the device by its color markings and.

They are composed primarily of z n o with small additions of other metal oxides such as bismuth cobalt magnese and others. Mov 07d511k metal oxide varistor semi conductors devices. A metal oxide varistor or mov protects sensitive electronic equipment from voltage spikes in the power line. Metal oxide varistor basics.

Then followed by a date code yyww for year and week. Varistors are voltage dependent nonlinear devices which have electrical characteristics similar to back to back zener diodes. Mov is the most commonly used type of varistor. 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.

The boundary between each grain and a neighbor forms a diode junction which allows. A gadget may have thousands of transistors resistors and other components but only one or two varistors.
