Zinc oxide varistor
Color: Blue
Verification: CE
Product description
The varistor is a voltage limiting type protection device. Using the non-linear 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 protecting the latter circuit. The main parameters of varistor are: varistor voltage, current capacity, junction capacitance, response time, etc.

working principle
When the voltage applied to the varistor is below its threshold, the current flowing through it is extremely small, which is equivalent to a resistor with an infinite value. That is, when the voltage applied to it is below its threshold, it is equivalent to an open state switch [1]. When the voltage applied to the varistor exceeds its threshold, the current flowing through it surges, which is equivalent to an infinitely small resistance. That is, when the voltage applied to it is above its threshold, it is equivalent to a closed state switch.
