Additional Details

The POZ3AN-1-103N-T00 is typically constructed with a multi-layer ceramic material. The specific voltage rating, capacitance, and surge current handling capabilities depend on the particular part's specifications. It's critical to consult the datasheet to ensure the varistor meets the specific requirements of the application. The 'T00' suffix often refers to the specific packaging and termination type for automated assembly processes. The varistor operates by rapidly decreasing its resistance when the voltage across it exceeds a specified threshold, effectively clamping the voltage and diverting the excess current away from the protected circuit. It's crucial to consider the clamping voltage and surge current withstanding capabilities when selecting a varistor for a particular application.
