Specifications: Description: Epoxy coated disc construction with radial leads. The Voltage Dependent Resistor is designed to protect device against transient voltage spikes. Connected directly across the power supply rails, when a voltage spike is sustained, the varistor rapidly changes impedance from its normal high impedance state while in standby mode, to a very low level, permitting absorbtion of the unwanted high voltage and protecting voltage sensitive components and circuits from damage. .
