PTC Resettable Fuses

PTC Resettable Fuses (Polymeric Positive Temperature Coefficient fuse) are thermally protected circuit components which provide over-current protection for electrical and electronic circuits. These fuses can be used in devices such as printers, power supplies, consumer electronics and industrial control units. The RHEF300 is a type of PTC Resettable Fuse that is specifically designed for consumer electronics applications.

RHEF300 Application Field

The RHEF300 is a PTC Resettable Fuse specifically designed for consumer electronics applications. It is designed to provide over-current protection for products such as TVs, desktop computers, laptops, game consoles and portable music players. Additionally, the RHEF300 is also suitable for protecting a variety of other consumer electronics and industrial control applications which require fast, reliable, and resettable overcurrent protection.

RHEF300 Working Principle

The RHEF300 features a positive temperature coefficient which allows it to detect and respond quickly to overcurrent conditions. When an over-current is detected, the PTC Resettable Fuse will begin to heat up and eventually reach its ‘trip’ point. At this point, the fuse disconnects the circuit and no current will be present. When the over-current condition is resolved, the fuse will cool and return to its ‘on’ state. This allows the circuit to be quickly powered on without having to reset or replace the fuse.The RHEF300 also features a unique mechanical earth feature which helps to ensure that the device is correctly installed and that earth leakage currents are minimized. This helps to improve the RHEF300’s performance and reliability, as well as helping to keep end-users safe.

Conclusion

The RHEF300 is a PTC Resettable Fuse specifically designed for consumer electronics applications. It is equipped with a positive temperature coefficient which enables it to detect and respond quickly to overcurrent conditions, and a mechanical earth feature to help ensure the device is correctly installed. As such, the RHEF300 is an ideal choice for providing reliable and quickly resettable over-current protection for a wide variety of consumer electronics and industrial control applications.
