Bourns 0.3 A Resettable Fuse 72V Radial Leaded Epoxy Polymer MF-RX030/72-0

Bourns MF-RX030/72-0 Resettable Fuse is a high-performance protective device with a 0.3 A hold current and 72V voltage rating designed to safeguard electrical and electronic circuits from excessive currents. This radial leaded device employs a cured epoxy polymer insulating material that complies with UL 94V-0 flame retardance requirements, ensuring high safety and durability.

Applications include low voltage power supply systems such as security and fire alarm panels, loudspeakers, and power transformers where reliable circuit protection is critical. The fuse quickly switches from a low resistance state to a high resistance state under overload or short circuit conditions and automatically resets when the fault is cleared and power is interrupted, eliminating the need for fuse replacement.

The compact size with dimensions of 7.4 mm length, 13.4 mm height, and 3.1 mm width allows for space-saving PCB mounting with radial leads for easy soldering and wire ending. The device operates efficiently over a temperature range from -40°C to 85°C with a power dissipation rating of 0.5 W.

Featuring UL, CSA, and TUV approvals, this fuse meets rigorous international standards for safety and performance, making it suitable for varied industrial and commercial electronic applications including automotive, medical equipment, instrumentation, computers, peripherals, audio visual, and telecommunication devices.

Automatically resets itself thousands of times after fault clearance. Maintenance-free operation with no fuseholder required. Compact radial lead design compliant with UL flame retardant standards. Protects circuits operating up to 72V in various industrial and commercial applications.

Reliable operation from -40°C to 85°C environment temperatures. Fast response to electrical overloads and short circuits. Approved by UL, CSA, and TUV for quality and safety. Ideal for use in security systems, power supplies, automotive, and instrumentation.
