While it may look similar to a capacitor you can identify the device by its color markings and.

Metal oxide varistor images.

The devices offer a choice of varistor voltages from 18v to 1820v and vrms voltages from 11v to 1100v. It is also a non linear device and provides very good transient voltage surge protection. A gadget may have thousands of transistors resistors and other components but only one or two varistors. Robin earl at dehn 8 jun 2015.

Movs or metal oxide varistors are a very popular product and widely used. Metal oxide varistors and multi layered varistors. Metal oxide varistor mov to overcome the limitations of semiconductor based varistors like silicon carbide varistors the metal oxide varistors mov have been developed. 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.

Metal oxide varistor is a voltage dependent resistor. A metal oxide varistor or mov protects sensitive electronic equipment from voltage spikes in the power line. Bourns mov 14d mov 20d metal oxide varistors are 14mm and 20mm radial leaded varistor devices which protect against overvoltage transients such as lightning power contact and power induction. 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 metal oxide varistor or mov is. This is useful for controlling how much electric current travels to certain parts of electronic devices. See more ideas about metal glass coating resistors. Metal oxide varistor basics.

They are composed primarily of z n o with small additions of other metal oxides such as bismuth cobalt magnese and others. Aug 24 2016 explore tge oxide varistors s board mov metal oxide varistor on pinterest. Siov 1 varistors have been proven to be excellent protective devices because of their application flexibility and high reliability. A metal oxide varistor is a device used as a component in electrical equipment the word varistor is short for variable resistor a resistor is a circuit that does not conduct electricity well.

The boundary between each grain and a neighbor forms a diode junction which allows. They are primarily protective devices to dump the current in excessive over voltage events and so save the circuit board or end equipment. Mov is the most commonly used type of varistor. The most common modern type of varistor is the metal oxide varistor mov.

Mov s are the most used component to protect heavy devices.
