Varistors(SMD) Countermeasure for Surge and Static Electricity
Conformity to RoHS Directive
AVR Series AVR-M, AVRL Types
Varistor (Variable resistor) is a nonlinear resistive element of the voltage dependence that resistance changes with applied voltage. Varistor is equivalent with Zener diode of two series connection. Therefore, do not have polarity.
