Large Absorbing Nonlinear Big Size 275V RMS 32mm MYL Metal Oxide Varistor MOV 32D431K Voltage Dependent Resistor VDR

 

 

Brief Introduction


Varistor 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.

Metal oxide varistor Application

 

Accroding to the market requirement for a high quality varistor, and based on the problems exit during production procedure, Aolittel developed a kind of high performance, reliable varistor special for surge protection devices(SPD), and established new production workshop specially for metal oxide varistors production.
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 varistor), the 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.Large Absorbing Nonlinear Big Size 275V RMS 32mm MYL Metal Oxide Varistor MOV 32D431K Voltage Dependent Resistor VDR 2
