Electronic components are the fundamental building blocks of electronic products. These include resistors, capacitors, inductors, diodes, transistors, integrated circuits, and more. By specific connections and combinations, these components enable various circuit functions such as signal processing, amplification, storage, and control—one example being the varistor.
A varistor is an essential overvoltage protection component. When the voltage in a circuit exceeds a certain threshold, the resistance of the varistor drops rapidly, diverting excessive current and preventing damage to the circuit components caused by overvoltage.
The protective function of varistors is critical for a wide range of electronic devices and appliances, extending their operational lifespan. Varistors are also widely used in applications such as lightning surge protection, suppression of inrush currents, and electromagnetic interference (EMI) mitigation.
With advantages such as high voltage tolerance, fast response speed, strong surge current handling capability, and large current capacity, varistors are used in numerous electronic products. So, what electronic products utilize varistors?
Varistors have a broad range of applications, spanning various fields from household appliances to industrial equipment.
In household appliances such as televisions, air conditioners, computers, refrigerators, and washing machines, varistors are commonly used at the power input for surge protection, ensuring stable operation even during voltage fluctuations or lightning strikes.
In communication devices such as mobile phones, routers, and base stations, varistors help protect communication lines and equipment from lightning or sudden voltage spikes.
In industrial control systems, automotive electronics, power strips, and other fields, varistors play an equally important role in safeguarding circuits against transient overvoltage impacts.
