Bourns 3.75 A Resettable Fuse 72V Radial Leaded Epoxy Polymer MF-RX375/72-0

Bourns MF-RX375/72-0 is a high-quality resettable fuse designed for protecting electrical and electronic circuits against excessive current and short circuits. Rated with a hold current of 3.75 A and a voltage rating of 72 V, this radial leaded fuse features an epoxy polymer insulating material that meets UL 94V-0 flame retardancy standards, ensuring safe and durable operation.

This fuse automatically resets itself thousands of times without maintenance, eliminating the need for replacement after fault clearance. It rapidly switches from a low resistance state to a very high resistance state upon overcurrent conditions, thereby protecting sensitive components in a wide range of industrial and commercial applications.

Its compact size and radial leads (0.81 mm diameter) make it suitable for PCB wire-ended mounting, contributing to simplified circuit designs. The time to trip is approximately 24 seconds at the rated current, with a trip current specified at 7.5 A. The fuse's power dissipation is 3.2 W, making it efficient for continuous use.

The operating temperature range spans from -40°C minimum to 85°C maximum, allowing it to function reliably in varied environments. Dimensions are precise, with a length of 23.51 mm, height of 29.51 mm, and width of 3.1 mm.

This Bourns Resettable Fuse is UL and RoHS certified, confirming compliance with critical safety and environmental standards. It finds prominent applications in security systems, power supplies and transformers, power switching devices, automotive and medical equipment, instrumentation and control systems, computers and peripherals, audiovisual equipment, and telecommunications.
