Varistor for power supply to instrumentation

With the development of science and technology, the field involved in our capacitors can be said to be very broad. Although it is a small varistor, its role is not negligible.

The varistor can be used for lightning protection and surge protection at the power inlet of the instrument. In such applications, the varistor is usually combined with a gas discharge tube, a fuse, a thermistor, etc. Play a role. If the varistor is applied to the protection of the AC circuit, the leakage current is increased because of its large capacitance. When designing the protection circuit, it is necessary to fully consider the varistor's large current capacity.

Everyone needs to do more homework before using it, so as to avoid unnecessary troubles.
