Zinc oxide varistor

Color: Blue

Verification: CE

Product description

The varistor is a kind of resistance device with nonlinear volt-ampere characteristics. It is mainly used for voltage clamping when the circuit is under overvoltage, and absorbs excess current to protect sensitive devices from power supply systems, surge protectors, Security system, motor protection, automotive electronics systems, household appliances

Product specifications

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.

Product advantages

1. Multiple lead forms: straight, bent and other special lead types
