Varistors(SMD)
Conformity to RoHS Directive
Countermeasure for Surge Voltage and Static Electricity
AVR Series AVR-M, AVRL Types
Varistors are voltage dependent nonlinear resistive elements with
a resistance that decreases rapidly when the voltage is over the
constant value.
Varistor is equivalent with Zener diode of two series connection.
Therefore, do not have polarity.
