Metal Oxide Varistor Mov

The metal oxide varistor or mov is sintered during the manufacturing operation into a ceramic semiconductor and results in a crystalline microstructure that allows movs to dissipate very high levels of transient energy across the entire bulk of the device.

Metal oxide varistor mov.

Bourns mov metal oxide varistors movs protect against overvoltage transients such as lightning power contact and power induction. These 7mm 10mm 14mm and 20mm radial leaded varistors feature high current handling high energy absorption capability and fast response times to protect against transient faults up to rated limits. A metal oxide varistor mov is a protection component used in power supply circuits that is powered directly from ac mains it is used to protect the circuit from high voltage spikes by varying its resistance. 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 is designed to protect various types of electronic devices and semiconductor elements from switching and induced lightning surges. Metal oxide varistor basics mov is the most commonly used type of varistor. The most common modern type of varistor is the metal oxide varistor mov. 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 boundary between each grain and a neighbor forms a diode junction which allows. Special medium voltage varistors mov square disk 5 7 10 14 20 23 60 500 v 60 550 v 600 15 000 a 25 ns. A metal oxide varistor or mov is the blue or orange colored circular component that you can commonly spot on the ac input side of any power supply circuit the metal oxide varistor can be considered as another type of variable resistor that can vary its resistance based on the applied voltage across it. The metal oxide varistor or mov is a voltage dependent nonlinear device that provides excellent transient voltage suppression.
