MF-R500-AP-14

Overview

The MF-R500-AP-14 is a PTC resettable fuse from the Bourns Multifuse MF-R series, designed for PCB mounting with radial leads. It features a holding current of 5.0 A and a trip current of 10 A at maximum voltage of 30 VDC. The device has a maximum rated current of 40 A and an initial resistance of 30 mOhms. Operating temperature ranges from -40°C to +85°C. Physical dimensions include a length of 17.4 mm, width of 7.6 mm, and height of 24.9 mm, with a lead spacing of 10.2 mm.

Feature Summary

Provides overcurrent protection through automatic circuit interruption upon thermal activation
Offers reusable functionality by resetting automatically after fault clearance and cooling
Utilizes polymer positive temperature coefficient technology for reliable performance

Applications

Protection of sensitive electronic components in low-voltage circuits
Overcurrent safeguarding in consumer electronics assemblies
Circuit protection within industrial control systems

Procurement Notes

Verify component authenticity against official Bourns documentation before integration. Confirm that the specific suffix indicates standard packaging rather than functional variation. Ensure supply chain sources are authorized distributors to guarantee material integrity and traceability. Cross-reference datasheet revisions to confirm compliance with current manufacturing standards.

Selection Notes

Select this component when applications require a 5.0 A holding current within a 30 VDC system. The radial leaded package suits through-hole PCB layouts requiring 10.2 mm spacing. Consider the 30 mOhms resistance for minimal voltage drop impact. Evaluate thermal dissipation requirements given the 85°C maximum operating limit.

Part Context

This part belongs to the Bourns Multifuse MF-R series of resettable fuses. These devices utilize conductive polymer technology to provide overcurrent protection. The series offers various current ratings and voltage options for diverse circuit protection needs across multiple industries.
