Bourns 2.5 A Resettable Fuse, 30 V Radial Leaded Epoxy Polymer MF-R250-0-10

Bourns MF-R250-0-10 is a 2.5 ampere resettable fuse designed for protecting electrical and electronic circuits against excessive currents and short circuits. It is rated for 30 volts and automatically switches from a low resistance state to a high resistance state under fault conditions, then resets once the fault is cleared. This makes it ideal for use in a wide variety of industrial and commercial applications.

The fuse features a compact radial leaded form factor with dimensions of 12mm length, 18.3mm height, and 3mm width. It uses a cured, flame retardant epoxy polymer insulating material that meets UL 94V-0 requirements, ensuring safety and durability. The lead diameter is 0.81mm with radial orientation for easy PCB mounting.

The MF-R250-0-10 fuse offers a hold current of 2.5A and a trip current of 5A, providing precise circuit protection. It operates reliably across a broad temperature range from -40°C minimum to 85°C maximum, with a power dissipation of 1.2 watts. The minimum resistance is 0.025 ohms and maximum resistance is 70 milliohms, ensuring efficient electrical performance.

This resettable fuse is RoHS and UL certified, assuring compliance with safety and environmental standards. It is maintenance free and designed for thousands of automatic resets, eliminating the need for fuse replacements.

Main applications include circuit protection in security systems, power supplies, automotive electronics, medical equipment, instrumentation, control systems, computers, audiovisual devices, and telecommunications equipment.

Whether used in industrial automation, laboratory equipment, or commercial electronics, this resettable fuse offers reliable and rapid protection against overcurrent conditions while enhancing operational safety and equipment longevity.
