Offers automatic circuit restoration after fault conditions clear
Designed for robust performance in high-voltage and high-temperature environments

Applications

Automotive electronics circuits
Industrial equipment power supplies
Telecommunications infrastructure
Consumer electronic devices

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm exact packaging and tape-and-reel specifications. Ensure the component meets all required safety certifications for the target application environment before finalizing procurement orders.

Selection Notes

Select this component when a 3.75 A hold current and 72 VDC rating are required for radial PCB mounting. Consider the 50 mΩ impedance and 40 A interrupt capability for circuit design constraints. Verify thermal derating requirements for operation near the upper temperature limit.

Part Context

This part belongs to the Bourns Multifuse MF-RX/72 series of polymeric resettable fuses. These components utilize advanced polymer PTC elements designed to provide reliable overcurrent protection in demanding applications while eliminating nuisance tripping caused by ambient temperature variations.
