Product name: MOV Varistors summary

Brief Introduction:
MOV varistors are nonlinear resistors mainly composed of zinc oxide as the main material of metal oxide semiconductor components,and they can be divided into symmetric (non-polarity) and asymmetric (with polarity) according to the voltage-ampere characteristic. The nonlinear resistors are more sensitive to voltage, when voltage reached one set value, resistance conducts rapidly.Due to characteristics of high effective nonlinear coefficient,large through-flow capacity,fast action and no continued flow,they are mainly used for the absorption of various operating surge & lightning wave voltage and lightning protection of electronic equipments,which can prevent such voltage interfering with the normal operation or damaging the various circuit elements.

Product Application:
Widely applied in surge protection of different Electronic Engineering areas:
1.Telecommunications
2.Electricity
3.Home appliances
Example: telephones,converter,power meter, power distribution cabinets, socket box, distribution box, power switch, power lightning protection box, voltage regulator, lightning arrester (SPD surge protection special).

Working principle:
When mov varistor in a rest state, relative to the protected electronic components, has a very high impedance (number megohm) without changing circuit characteristics of the original design.When achieve the momentary surge voltage (more than breakdown voltage of the metal oxide varistor), the mov varistor impedance will be low (only a few ohms.) and caused the original short circuit.In other words, electronic products or components are thus protected.
