Littelfuse 1 A Resettable Fuse 30V DC Radial Lead Orientation RHEF100

The Littelfuse RHEF100 is a high-quality 1 A resettable fuse operating at 30V DC with radial lead orientation, designed to protect electrical circuits from excessive currents efficiently and reliably. This PolySwitch™ PTC device from the RHEF series features a trip current of 1.8A and is capable of rapidly switching from a low resistance state to a high resistance state in the event of an electrical overload or short circuit.

Its compact dimensions of 9.7mm length, 13.6mm height, and 3mm width make it suitable for PCB wire-ended mounting, ensuring a space-saving solution without the need for a fuse holder. The fuse maintains stable performance with a holding current of 1A and a power dissipation rating of 1.4W, handling electrical loads safely.

Engineered to operate within a temperature range from -40°C to 60°C, the RHEF100 resettable fuse is versatile for multiple industrial and commercial applications. It is UL, CSA, TUV, and RoHS approved, which guarantees compliance with stringent international safety and environmental standards.

This device is maintenance-free and automatically resets itself thousands of times, providing long-lasting circuit protection. Its low resistance characteristics minimize energy loss during normal operation and enhance the overall efficiency of electrical and electronic systems.

Typical applications include security systems, power supplies and transformers, power switching devices, automotive electronics, medical equipment, instrumentation and control devices, computers and peripherals, as well as audio-visual and telecommunications equipment.
