Varistors, as important electronic components, have a wide range of applications and significant advantages. They play a key role in fields such as consumer electronics, automotive industry, and industrial automation, ensuring the safe and reliable operation of circuits and devices.

In the field of consumer electronics, varistors are commonly used to protect circuits from overvoltage or overcurrent damage. For instance, in mobile phones, varistors are used to protect power circuits, charging interfaces, and audio interfaces. When abnormal voltage or current conditions occur in the circuit, varistors respond quickly, providing protection and preventing damage to electronic components and circuit boards. In household appliances, varistors also play a similar protective role, ensuring the safety and reliable operation of the appliances.

In the automotive industry, varistors are utilized in safety systems such as airbag systems, playing a critical role in protecting the safety of drivers and passengers. In the event of a collision, varistors detect the impact force quickly and trigger airbag inflation, providing effective protection for the occupants. Furthermore, varistors are extensively applied in electronic systems and control systems of vehicles, providing overvoltage and overcurrent protection, and enhancing the overall reliability of the vehicle"s electronic systems.
In the field of industrial automation, varistors are equally important. They are used for the protection of PLCs and motor control circuits. When abnormal voltage or current conditions occur, varistors respond rapidly, providing protection and ensuring the normal operation of automated equipment. Additionally, varistors are employed in industrial control systems for overvoltage protection, overcurrent protection, short-circuit protection, and more, ensuring the stability and reliability of equipment and processes.
Overall, varistors have extensive applications in various fields, including consumer electronics, automotive industry, and industrial automation. Their high sensitivity and fast response make them an ideal choice for protecting circuits and ensuring the safety of devices.
