The characteristic of the varistor is that when the voltage applied to it is lower than its threshold "Un", the current flowing through it is extremely small, which is equivalent to a closed valve. When the voltage exceeds Un, its resistance The value becomes smaller, so that the surge of current flowing through it has little effect on other circuits, thereby reducing the impact of overvoltage on subsequent sensitive circuits. Utilizing this function, it is possible to

MOV-20D Metal Oxide Varistor Wide Voltage Range Various Diameter Size Options Before choosing a varistor, you should first understand the following related technical parameters: The nominal voltage refers to the voltage value at both ends of the varistor under the specified temperature and DC current [1]. Leakage current refers to the current value flowing through the varistor when the maximum continuous DC voltage is applied at 25°C. The level voltage refers to the peak

Non-Polarity MOV-14D Metal Oxide Varistor Low Leakage Current Strong Surge Withstand Capacity What is a varistor used for? The biggest feature of the varistor is that when the voltage applied to it is lower than its threshold "UN", the current flowing through it is extremely small, which is equivalent to a closed valve. When the voltage exceeds UN, its resistance The value becomes smaller, so that the current flowing through it increases sharply and the influence on other

Non-Polarity MOV-10D Metal Oxide Varistor For Voltage Spike Protection How to use a metal oxide varistor in a circuit? When the voltage is within the rated limits, the resistance of the MOV will be very high, so all the current flows through the circuit and no current flows through the MOV. But when there is a voltage spike on the mains it will appear directly on the MOV since it is in parallel with the AC mains. This high voltage will reduce the resistance value of the MOV
