Introduction

The SMD0805P050TFA is a PTC Resettable Fuse which is used to protect electronic circuits from damage due to over current or over temperature events. These fuses provide a dependable method of resetting circuit protection after a fault has occurred. The SMD0805P050TFA has a low profile package design, small board area requirements, and a wide temperature operating range.

Application field

The SMD0805P050TFA is commonly used for consumer electronics, telecom, power, industrial, medical, automotive, and other applications. It can be used as an alternative to circuit breakers, electromechanical, and thermal fuse designs. It has been widely used in USB data lines, household appliances, telecommunications equipment, portable electronic equipment, circuit protection of mobile phones and other occasions.

Working Principle

The SMD0805P050TFA is a PTC resettable fuse that works by changing its resistance when a fault (surge or over temperature) occurs. When this occurs, the device will act like an open circuit, significantly reducing the current flow. The device will then self-restore when it has cooled and the fault has been removed. These fuses are able to reset multiple times, meaning they can provide reliable circuit protection in applications that experience repeated faults.

The SMD0805P050TFA is made from a special ceramics-filled epoxy material which has a high thermal conductivity and low thermal mass. This combination allows it to react rapidly to changes in temperature and current levels. The fuse also has a low profile package design, small board area requirements, and a wide temperature operating range, making it an ideal choice for many electronic applications.

Conclusion

The SMD0805P050TFA is a PTC resettable fuse that provides reliable protection from over current and over temperature events. It has a low profile package design, small board area requirements, and a wide temperature operating range, making it a great choice for many applications. The SMD0805P050TFA is widely used in consumer electronics, telecom, power, industrial, medical, automotive, and other applications.
