Additional Details

The '05' in the part number suggests a diameter of 5mm. 'E050' typically indicates a voltage rating of 50V. It's crucial to consult the Vishay datasheet to confirm these values and obtain detailed electrical characteristics, including the clamping voltage, maximum surge current, and energy handling capability. The datasheet also provides information on the varistor's operating temperature range and its derating characteristics at elevated temperatures.

This varistor operates by changing its resistance in response to voltage spikes. When the voltage across the varistor exceeds its rated voltage, the varistor's resistance rapidly decreases, diverting the surge current away from the protected circuit. After the surge, the varistor returns to its high resistance state, allowing normal circuit operation. It is a cost-effective and reliable solution for protecting electronic equipment from transient voltage surges.
