Key Features
- 0.75A hold current with automatic reset after fault clears, eliminating need for manual fuse replacement
- 60V maximum voltage rating in a compact radial through-hole disk package (10.4mm x 16mm) for PCB-mount protection
- RoHS and REACH compliant PPTC technology provides reliable overcurrent protection without sacrificing circuit availability
Applications
The MF-R075 resettable fuse is used to protect USB power lines, battery packs, and low-voltage DC circuits from sustained overcurrent faults in consumer electronics, industrial controllers, and telecommunications equipment. Its 0.75A hold current makes it well suited for protecting 5V USB ports, UART interfaces, and sensor power rails where nuisance trips must be avoided during normal 0.5A to 0.75A operation. The radial leaded package enables easy through-hole PCB mounting in prototype and production boards requiring reliable self-resetting circuit protection.

Frequently Asked Questions
What is the hold current and trip current of the Bourns MF-R075 resettable fuse?
The MF-R075 has a hold current of 0.75A, meaning it passes up to 0.75A continuously without tripping. The trip current is typically 1.5A at 23°C, at which point the PPTC element rapidly increases resistance to limit fault current, protecting connected circuits rated for up to 60V.
How does the MF-R075 resettable fuse restore circuit operation after an overcurrent event?
After the fault is cleared and power is removed or reduced below the trip threshold, the MF-R075's PPTC polymer element cools and returns to its low-resistance conductive state within seconds to minutes. This self-resetting behavior at 0.75A hold current eliminates manual fuse replacement, reducing maintenance burden in deployed equipment and improving system uptime.
For USB 2.0 port protection on a 5V bus, does the MF-R075 provide adequate current headroom?
Yes. USB 2.0 standard load current is 0.5A, well within the MF-R075's 0.75A hold current, so the fuse will not nuisance-trip during normal operation. The 60V voltage rating far exceeds the 5V bus level, and the 1.5A trip current provides protection against sustained short-circuit conditions that could damage the host controller or cables.
What are the physical dimensions and mounting style of the MF-R075, and how does it fit on a standard PCB?
The MF-R075 is a radial leaded through-hole component in a disk package measuring 10.4mm in length and 16mm in height. Its radial lead configuration allows direct insertion into standard 2.54mm spaced PCB holes, making it compatible with wave-soldering and manual assembly processes in both prototype and production runs.
