Bourns Resettable Fuse Radial Lead 72V Voltage 3.75A Hold Current 40A Current Rating MF-RX375/72-0

Bourns MF-RX375/72-0 is a high-quality resettable fuse designed for protecting electrical and electronic circuits against excessive currents. Featuring a voltage rating of 72V and a hold current of 3.75A, this radial leaded fuse rapidly transitions from a low resistance state to a high resistance state when an overload or short circuit occurs, ensuring reliable circuit protection in industrial and commercial systems.

Constructed with a cured, flame retardant epoxy polymer insulating material meeting UL 94V-0 flammability standards, this fuse is UL and RoHS certified, promising safety and environmental compliance. The small-size design with radial leads allows easy PCB mounting without requiring a fuseholder, facilitating compact and efficient circuit designs.

With a trip current of 7.5A and a current rating of 40A, the fuse provides robust protection suitable for a wide range of applications including security systems, power supplies, transformers, power switching devices, automotive electronics, medical instruments, computer peripherals, audio-visual equipment, and telecommunications.

Automatically resets itself thousands of times, reducing maintenance and replacement costs. Protection against overcurrents with rapid trip response within 24 seconds. Wide operating temperature range from -40°C to 85°C ensures use in varied environments.

Power dissipation limited to 3.2W for energy efficiency. Compact physical dimensions measuring 23.51mm length, 29.51mm height, and 3.1mm width support integration in tight spaces. Radial lead orientation and 0.81mm lead diameter improve mounting versatility.

This solution is ideal for demanding industrial, laboratory, and commercial applications requiring intermittent short-circuit and overload protection combined with automatic reset capabilities. Bourns resettable fuses provide a reliable, maintenance-free approach to enhancing circuit safety and uptime.
