25D Series 25D101K 25D431K 25D561K Disc Varistor , MOV Practical Zinc Oxide SPD Lightning Protection Varistor
|
...Varistor, Practical Zinc Oxide Lightning Protection Varistor The varistor is a voltage limiting protection device. Utilizing the nonlinear characteristics of the varistor, when an overvoltage occurs between the two poles of the varistor, the varistor can clamp the voltage to a relatively fixed voltage value, thereby realizing the protection of the subsequent circuit. The main parameters of varistors are: varistor......
