Additional Details

The POZ3AN-1-203N is constructed from a zinc oxide (ZnO) based ceramic material. The key specifications to consider when selecting this varistor are its clamping voltage, surge current capability, capacitance, and leakage current. The '203N' portion of the part number likely refers to its specific voltage rating and capacitance. The varistor operates by rapidly decreasing its resistance when the voltage across it exceeds a predetermined threshold, effectively clamping the voltage and diverting the excess current away from protected components. It is important to consult the manufacturer's datasheet for detailed specifications and application guidelines to ensure optimal performance and protection.
