Metal oxide varistor symbol.

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. Modern varistor schematic symbol. In its early days the varistor was represented as two diodes placed anti parallel to each other as shown in figure due to its diode like behaviour in both directions of current flow. Industrial high energy varistors provide a much higher surge and energy rating than regular movs metal oxide varistors and also possess various terminals to fit different assembly requests or conditions.

The voltage and current characteristics of a varistor are nonlinear in nature. 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. Need some help identify a varistor. Metal oxide varistors mov.

A varistor is a voltage dependent resistor vdr. The word is composed of parts of the words. Since sic varistors had some serious drawbacks another type of. The metal oxide varistor or mov is a voltage dependent nonlinear device that provides excellent transient voltage suppression.

Are external components required for hlk pm01. Help to choose fuse varistor and or tvs diode. Also the voltage and current characteristics of a varistor are suitable for both dc and ac supplies. Varistors are used as control or compensation elements in circuits either to provide optimal operating conditions or to protect against excessive transient voltages.

Generally varistors are made from semiconductor materials. The resistance of a varistor is variable and depends on the voltage applied. Help identifying a varistor. Varistors can be considered to be a form of resistor in which the resistance changes significantly with the applied voltage.

The basics of metal oxide varistor mov along with its working and specifications are given and also its performance and other features. How to choose the right metal oxide varistor mov 0. This type is commonly known as the metal oxide varistor mov.
