Metal Oxide Varistor (MOV) as one nonlinear resistance element is mainly made of zinc oxide (ZnO), which has very high surge capacity and big nonlinear coefficient.
Below the threshold voltage, its resistance is very high, nearly no current flows through, but above the threshold voltage, the resistance reduces sharply, huge current can be discharged.
Due to this characteristic, varistor as a protection component in electronic and electrical equipment can absorb abnormal over-voltage and lightning surge. MOV’s unique ability to modify its resistance provides a robust shield for electronic devices against voltage spikes.
By choosing and employing MOVs, one can enhance the reliability and stability of electronic systems, ensuring that devices operate safely and effectively even in volatile and unpredictable power conditions.
