Additional Details

The POZ3AN-1-103N-T01 is constructed from a zinc oxide (ZnO) based ceramic material that exhibits a non-linear voltage-current characteristic. When the voltage across the varistor exceeds a certain threshold, its resistance rapidly decreases, diverting the surge current away from protected components. The '103N' portion of the part number likely indicates a specific voltage rating and capacitance value. The 'T01' suffix usually refers to a specific packaging or termination style optimized for automated assembly. The key specifications to consider when selecting this varistor are its clamping voltage, surge current capability, capacitance, and leakage current. It's important to consult the manufacturer's datasheet for detailed specifications and application guidelines to ensure optimal performance and protection.
