PTC Resettable Fuses: PTCCL05H630HBE application field and working principle

PTC (positive temperature coefficient) resettable fuses are electronic components that are designed to provide reliable over-current protection for a variety of electrical and electronics products. They are usually used in applications where fast acting fuses cannot be used, since they can be reset manually after tripping. The PTCCL05H630HBE is a PTC resettable fuse that is widely used in automotive, consumer, industrial, and medical applications. It is an axial leaded, two-layer resettable fuse with over-current protection capabilities that makes it ideal for a range of application fields. This article provides an overview of the application fields for the PTCCL05H630HBE as well as its working principle.

Overview of PTCCL05H630HBE Application Fields

The PTCCL05H630HBE is a robust and economical resettable fuse that is suitable for a wide range of applications, including automotive, consumer, industrial, and medical. In automotive applications, this fuse is used in exhaust gas recirculation systems, battery isolator systems, and power steering systems. As for consumer applications, the PTCCL05H630HBE is used in electronic appliances such as hair dryers, microwaves, and toasters. In industrial and medical applications, this resettable fuse has been used to provide over-current protection for voltage regulators, electric heating tapes, and medical imaging scanners.

Working Principle of PTCCL05H630HBE

The PTCCL05H630HBE is a two-layer resettable fuse with an axial leaded design. It typically consists of two layers of film, one made of polyethylene oxide and another made of polyvinylidene fluoride. These two layers are separated by a thermistor band. At low temperatures, the thermistor band is open and the fuse is in ON mode. When increasing the temperature, the thermistor band migrates over time to an OFF mode.When the fuse is in the ON mode, it behaves like an ordinary electrical circuit. The current flows through its polyethylene oxide and polyvinylidene fluoride layers, and is divided into two parts, one part flowing through the thermistor band and the other part bypassing it. However, when the device surpasses its maximum current rating, the temperature inside the fuse increases. This increase in temperature causes the thermistor band to migrate to the OFF mode, which blocks the flow of current through the device. Once the temperature of the PTCCL05H630HBE reaches a certain level, the fuse will be pushed into the OFF mode. To reset the device, the temperature has to be reduced to its initial value, which takes approximately one to two minutes. The resetting process can be quickly done by either reducing the temperature of the environment or replacing the device with a new one.

Conclusion

The PTCCL05H630HBE is a robust and economical PTC resettable fuse that is widely used in a wide range of applications, including automotive, consumer, industrial, and medical applications. This resettable fuse has an axial leaded, two-layer design that enables it to provide reliable over-current protection while conserving energy. Its working principle is based on the migration of a thermistor band from an ON to an OFF mode when the device surpasses its maximum current rating. This article provided an overview of the application fields and working principle of the PTCCL05H630HBE, and it is hoped that this information will prove useful for those who are looking to use this device in their projects.
