Practical application of varistors

    Electronic components are the basis of electronic products. They each undertake different functions and work together to ensure the normal operation of electronic products. Electronic components are the basic building blocks of electronic products. They include capacitors, resistors, inductors, diodes, transistors, integrated circuits, etc. These components can realize various functions of the circuit, such as signal processing, control, etc. through specific connections and combinations.

    Varistor is an important overvoltage protection component. When the voltage in the circuit exceeds a certain threshold, the resistance of the varistor will decrease rapidly, thereby diverting excessive current and preventing the components in the circuit from being damaged by overvoltage.

    The protective effect of varistor is very important for various electronic equipment and electrical products, extending the service life of the equipment. Varistors are also commonly used in lightning protection and surge current protection, as well as electromagnetic interference suppression. Varistors have the advantages of high voltage resistance, fast response speed, strong surge current resistance, and large current capacity, which make varistors used in many electronic products.

    In household appliances, such as televisions, air conditioners, computers, refrigerators, washing machines, etc., varistors are often used for surge protection at the power input to ensure that the equipment can still operate stably under voltage fluctuations or lightning strikes.

    In industrial control systems, automotive electronics, sockets and other fields, varistors also play an important role in protecting circuits from transient overvoltage shocks.

    In communication equipment, such as mobile phones, routers, base stations, etc., varistors are used to prevent lightning or voltage mutations from damaging communication lines and equipment.

    The application range of varistors is very wide, covering most electronic products, from household appliances to various fields of industrial equipment, where varistors are used.
