Fielect 10Pcs Voltage Dependent Resistors AC 350V 14D561K-F7.5-L Radial Lead Disc Varistors

Specific epoxy coated disc construction with radial leads, long life use. The Voltage Dependent Resistor is designed to protect equipment against transient voltage spikes. Connected directly across the power supply rails. When a voltage spike is encounted, the varistor rapidly changes impedance from its normal high impedance state to a very low level in standby mode. Can permit absorbtion of the unwanted high voltage and protect voltage sensitive components and circuits from damage. Widely used in power supply, industrial equipment, lighting products, automotive electronics and home appliance etc.
