Overview

The Bourns MF-RX025/72-2-17 is a radial leaded PPTC resettable fuse from the Multifuse MF-RX series. It provides overcurrent protection with a hold current of 250 mA and a trip current of 500 mA. The device supports a maximum voltage of 72 VDC and features a resistance of 1.95 Ohms. It operates within a temperature range of -40°C to +85°C, dissipates 450 mW, and has a lead spacing of 5.1 mm.

Feature Summary

Provides automatic circuit recovery after fault clearance without manual replacement
Offers robust protection against short circuits and overcurrent conditions in electronic systems
Features a compact radial leaded package suitable for PCB mounting applications

Applications

Consumer electronics power supply input protection
Industrial control system circuit safeguarding
Telecommunications equipment overcurrent defense

Procurement Notes

Verify the specific suffix '-2-17' against official Bourns documentation to confirm reel packaging and tape-and-reel specifications. Ensure the component matches the exact electrical ratings required for the target application circuit design.

Selection Notes

Select this component when a low-resistance radial PTC fuse is needed for 72V DC systems. Compare the 250 mA hold current against normal operating loads to ensure reliable tripping during fault conditions while maintaining stable performance under continuous operation.

Part Context

This part belongs to the Multifuse MF-RX series, designed for general-purpose circuit protection. It utilizes polymeric positive temperature coefficient technology to limit current flow during faults. The series is recognized for its reliability in protecting sensitive components across various industrial and consumer markets.

Replacement Considerations

Consult official substitution lists for equivalent radial PPTC fuses with matching 250 mA hold current and 72 VDC rating. Verify that alternative parts maintain identical thermal characteristics and physical footprint dimensions for direct board compatibility.
