Product Description
Bourns MF-RM005/240-2 resettable fuse is designed to provide reliable overcurrent and overtemperature protection for electrical and electronic circuits. Featuring a hold current of 0.05A and rated at 1A current at 240V AC, this radial lead fuse helps to safeguard components in a variety of applications.
The compact form factor, with dimensions measuring 8.3mm length, 12.9mm height, and 3.8mm width, allows easy integration into printed circuit boards. The fuse’s radial leads with a 0.51mm diameter facilitate secure soldering connections. It dissipates up to 0.9 watts of power and presents a minimum resistance of 18.5 ohms.
Engineered to operate over a temperature range from -20°C to 85°C, the MF-RM005/240-2 fuse employs a flame retardant epoxy polymer that meets UL 94V-0 standards, ensuring safety and durability. Certified by UL and compliant with RoHS directives, it meets international quality and environmental standards.
This fuse works by rapidly transitioning from a low resistance state to a very high resistance state during electrical overload or short circuit conditions, thereby protecting connected devices effectively. Once the fault is cleared and power removed, it automatically resets to the low resistance state, allowing thousands of automatic resets without the need for replacement or maintenance.
The fuse is suitable for use in security systems, power supplies and transformers, power switching devices, automotive and medical equipment, instrumentation and control systems, computers and peripherals, as well as audio visual and telecommunications equipment.
Its maintenance-free design reduces downtime and repair costs. The radial leaded configuration enables straightforward PCB mounting. Construction with flame retardant materials enhances safety in critical applications. The MF-RM series is faster than traditional bimetallic switch designs and exhibits reduced susceptibility to electromagnetic interference.
The Bourns MF-RM005/240-2 resettable fuse is an ideal choice for engineers looking for dependable, reusable circuit protection in industrial, commercial, and consumer electrical devices.
