Zinc oxide varistor
Brief Introduction:
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).
