Mov Varistors Of Metal Oxide Varistor - China

price: contact company for price

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.

Working principle:

When <a href=http://www.dxmht.com/products/varistors.htm>varistors</a> 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.
