Most electronic applications need to be protected from transient voltage surges that are caused by lightning or other sources. The B72220T2271K105 is a high performance device designed to help protect sensitive electronic components and circuits within a variety of applications.

Application Field

The B72220T2271K105 provides protection for modern computer systems, consumer electronics, automotive electronics, industrial plant automation, medical electronics and communications systems. It has an incredible total surge rating of 12A, breaking down into an 8/20 uS peak pulse surge rating of 25A,which makes it extremely versatile. It also has excellent clamping capabilities and excellent electrical characteristics, making it ideal for a wide variety of applications.

Working Principle

The B72220T2271K105 is a high performance metal oxide varistor (MOV) that is designed to protect sensitive electronics from transient voltage surges. It is constructed of zinc oxide based material with a plastic casing and two soldering terminals. It works by limiting the voltage to a predetermined voltage, then clamping that voltage so that the excess energy can be redirected and dissipated as heat energy. This helps to protect the electronics from the surges and prevent them from becoming damaged.

When a voltage surge is encountered, the B72220T2271K105 will automatically reduce the voltage to a safe level then clamp that voltage level. This clamping feature is what makes the B72220T2271K105 so effective. As the surge passes through, the voltage will remain at a safe level until the surge dissipates. This protects the sensitive components from being damaged due to the excessive voltage.

In addition to the clamping feature, the B72220T2271K105 also features excellent endurance and thermal properties. It is capable of handling large amounts of current surge and is able to operate up to temperatures of 125 degrees Celsius. This makes it an ideal choice for applications that require high reliability and long term protection.

Conclusion

The B72220T2271K105 is a high performance metal oxide varistor that is specifically designed to provide protection from transient voltage surges. It features excellent clamping capabilities, endurance, and thermal properties, making it an ideal choice for a variety of applications. This makes it a great choice for protecting sensitive electronics and preventing damage to them in the event of a voltage surge.
