Metal Oxide Varistors (MOV)

Metal Oxide Varistors (MOVs) are electronic devices designed to protect electrical circuits from overvoltages and current spikes. Made from metal oxide materials, these devices exhibit a resistance that varies with the applied voltage; under normal conditions, they have high resistance, while during overvoltage events, their resistance drops dramatically, allowing excess current to be diverted to ground. MOVs are commonly used in electrical equipment and protection devices, such as power supplies, telecommunications systems, and electrical distribution networks. They provide effective protection against transient events, helping to ensure the safety and longevity of circuits and equipment.Electrostastic Discharge Suppressors (ESD)
