MF-R600-AP

Overview

The Bourns MF-R600-AP is a radial leaded PTC resettable fuse from the Multifuse series. It features a hold current of 6 A and a trip current of 12 A, with a maximum voltage rating of 30 VDC. The device has a minimum resistance of 20 mOhms and a maximum fault current rating of 40 A. Operating temperatures range from -40°C to +85°C. Physical dimensions include a length of 19.3 mm, width of 7.6 mm, and height of 31.9 mm, with a lead spacing of 10.2 mm.

Feature Summary

• Provides automatic circuit protection by increasing resistance in response to overcurrent conditions
• Restores normal operation automatically after cooling following fault clearance
• Designed for PCB mounting with radial leads for through-hole integration

Applications

• Overcurrent protection in industrial control systems
• Circuit safeguarding in telecommunications equipment
• Protection for power supplies and battery packs

Procurement Notes

Verify component authenticity against official Bourns documentation before integration. Confirm that the specific suffix matches project requirements, as variations may exist. Ensure compliance with relevant safety standards and environmental directives applicable to the final assembly. Cross-reference datasheet parameters with system design limits to guarantee reliable performance under expected operating conditions.

Selection Notes

Select this component when a high-current radial solution is required for low-voltage DC circuits. The 6 A hold current suits applications needing substantial continuous load capacity. Verify that the 30 VDC rating aligns with the system's maximum operating voltage. Consider the physical footprint and lead spacing constraints during PCB layout to ensure proper mechanical fit and thermal management.

Part Context

This part belongs to the Bourns Multifuse MF-R series, which offers various current ratings for different protection needs. The MF-R600-AP specifically addresses higher current applications compared to lower-rated variants in the same family. It utilizes polymeric positive temperature coefficient technology for reliable, reusable circuit protection without manual replacement.

Replacement Considerations

Direct substitutes within the same series include MF-R500-AP for lower current requirements or MF-LR600N-AP for surface mount alternatives. Verify electrical parameters match exactly when swapping components. Ensure package type compatibility if transitioning between radial and surface mount technologies.
