It can be used in both AC and DC circuits, and is suitable for a wide range of frequencies.

The B72580T0400K062 Varistor is particularly popular in applications that demand reliable voltage protection, such as uninterruptible power supplies (UPSs), TVs, air conditioners, computers, electronic cash registers, and security systems. It is also used for surge protection for trains, elevators, and electronic machine tools. In automotive applications, the B72580T0400K062 Varistor is used to protect against transient voltage spikes.

Working Principle

The Varistor is an electronic component that is designed to provide regulated and consistent overvoltage protection. It works by reducing the voltage that passes through it when the voltage in the circuit exceeds the rated level. The component contains a ceramic body that is filled with conductive metal oxide particles. The composition of these particles is designed to provide the required voltage protection.

When the applied voltage passes through the Varistor, the particles of metal oxide are displaced due to electrostatic forces, creating a resistance path that limits the amount of current that can flow through the component. This is known as the clamping action, and is what protects the circuit from overvoltage. As the applied voltage rises, the clamping action is increased in proportion, thus providing a greater level of protection. As the applied voltage decreases, the clamping action is reduced, allowing the circuit to operate normally.

Conclusion

The B72580T0400K062 Varistor is designed for applications that require reliable and consistent overvoltage protection. It is commonly used in a variety of applications, both in AC and DC circuits, such as UPSs, TVs, air conditioners, computers, and automotive applications. It works by reducing the voltage that passes through it when the voltage in the circuit exceeds the rated level. It utilizes a ceramic body filled with conductive metal oxide particles, which create a resistance path that limits the current that can flow through the component.
