Description
Brief Introduction:
varistors is nonlinear resistor 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.
Advantages:
1.Wide voltage range
2.Large through-flow capacity
3.High effective nonlinear coefficient
4.Little leakage current
5.Symmetrical volt-ampere characteristic
6..Low residual voltage
7.Fast action
8.No continued flow.
Metal oxide varistor 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).
