Varistor Applications Small Appliance Surge Protection

In the event of a lightning surge, rapid transmission through the power grid, although attenuated, may still cause thousands of volts when the household appliances are placed indoors. The duration of this high-voltage pulse is very short, only tens to hundreds of microseconds. Not enough to burn home appliances such as televisions, air conditioners, and washing machines, but it poses a great threat to the semiconductor components inside the appliance. Bytes affect the use effect and life span of household appliances.

To solve the lightning surge that household appliances may suffer, many home appliances are equipped with varistors such as televisions, air conditioners, washing machines, refrigerators, and computers. Metal oxide varistors, which have excellent non-linear volt-ampere characteristics, as well as rapid response speed, large flow capacity, no freewheeling, low residual voltage, etc.

It is widely used as overvoltage protection and surge absorption components for circuits, devices and components.
