Littelfuse 12 A Resettable Fuse, 16V Radial Lead RGEF1200

Littelfuse RGEF1200 resettable fuse features a 12 A current rating and operates at 16 V with a rapid trip response time of 7.5 seconds. It is designed for electrical and electronic circuit protection, employing PolySwitch™ RUEF and RGEF series technology to swiftly change from low resistance to high resistance during overloads or short circuits. The fuse automatically resets and returns to a low resistance state after fault correction and power removal.

Built to UL, TUV, CSA, and RoHS standards, this fuse incorporates radial lead orientation for PCB wire-ended use. It requires no fuse holder and supports maintenance-free operation for thousands of cycles. The compact size (17.5 mm length x 28 mm height x 3.5 mm width) makes it ideal for PCB space-saving applications.

The device consistently holds current at 12 A while tolerating trip currents up to 20.4 A, with minimal resistance ranging from 0.003 ohms to a maximum of 9 milliohms. It dissipates 4.2 W power during operation and functions reliably within the temperature range of -40 °C to 60 °C.

This resettable fuse is widely applicable in security systems, power supplies and transformers, power switching devices, automotive and medical equipment, instrumentation and control devices, computers and peripherals, as well as audio visual and telecommunications equipment. Its automatic reset capability enhances system safety and reliability, minimizing downtime and maintenance needs in industrial, commercial, and laboratory environments.
