Metal Oxide Varistor-(MOV)


Metal Oxide Varistor-(MOV) :

A MOV is a voltage sensitive breakdown device which is commonly used to limitovervoltage conditions (electrical surges) on power and data lines. When the applied voltage exceeds the breakdown point, the resistance of the MOV decreases from a very high level (thousands of ohms) to a very low level (a few ohms). The actual resistance of the device is a function of the rate of applied voltage and current
