• •Descriptions:
• •1.Specific epoxy coated disc construction with radial leads, long life use.
• •2.The Voltage Dependent Resistor is designed to protect equipment against transient voltage spikes.
• •3.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.
• •4.Can permit absorbtion of the unwanted high voltage and protect voltage sensitive components and circuits.
• •5.Widely used in power supply, industrial equipment, lighting products, electronics and home appliance etc.
