Bourns 5 A Resettable Fuse 30V Radial Leaded Device MFR Series MF-R500

Bourns MF-R500 resettable fuse is a compact, radial leaded device rated at 5 Amps hold current and 30 Volts. It is engineered to protect sensitive electrical and electronic circuits by automatically switching from a low resistance state to a high resistance state under overload or short circuit conditions. Once the fault is cleared and power removed, the fuse resets itself, allowing maintenance-free and reliable circuit protection.

This fuse is constructed with cured flame retardant epoxy polymer insulating material compliant with UL 94V-0 requirements, ensuring safe and durable operation. The MF-R500 fuse features a time to trip of 14.5 seconds at 10 Amps trip current, making it well suited for precise protection where controlled reaction times are necessary.

Operating within a wide temperature range from -40°C to 85°C, and with a power dissipation of 3 Watts, this device is stable across varying environmental conditions. Its compact form factor (17.4 mm length, 24.9 mm height, and 3 mm width) and radial lead orientation with 0.81 mm diameter leads facilitate easy PCB mounting without needing a fuse holder.

The Bourns MF-R series, including the MF-R500 model, is UL and RoHS certified, making it compliant with international safety and environmental standards. Its applications include security systems, power supplies and transformers, power switching devices, automotive and medical equipment, instrumentation and control systems, computers, audiovisual, and telecommunications equipment.

The fuse's ability to rapidly transition between resistance states under fault conditions ensures that circuits are protected against excessive currents without permanent fuse replacement. This makes it suitable for industrial, laboratory, manufacturing, and commercial electronics environments requiring dependable overcurrent protection.

Automatically resets itself thousands of times for maintenance-free operation. Rated hold current of 5 Amps and trip current of 10 Amps. Compact radial leaded design with flame retardant epoxy polymer insulation. Operates between -40°C and 85°C with a time to trip of 14.5 seconds.
