MF-RG800-0-14

Overview

The Bourns MF-RG800-0-14 is an automotive-grade polymeric positive temperature coefficient (PPTC) resettable fuse designed for circuit protection. It features a radial leaded package and complies with AEC-Q200 standards. The device has a holding current of 8A and a maximum voltage rating of 16V. Initial resistance is typically 5.6 mOhms, while post-trip resistance reaches a maximum of 17.5 mOhms. It operates within a temperature range of -40°C to 85°C.

Feature Summary

• Provides fast tripping response for overcurrent protection in automotive applications
• Compact radial leaded design suitable for space-constrained PCB layouts
• Automotive-grade construction ensuring reliability under harsh environmental conditions

Applications

• Automotive electronic circuit protection
• Power supply input protection
• Signal line surge suppression

Procurement Notes

Verify the specific ordering suffix to ensure correct packaging and compliance requirements. Confirm that the 16V rating aligns with system voltage levels. Check datasheet specifications for trip time characteristics relative to expected fault currents. Ensure thermal management considerations are addressed during integration.

Selection Notes

Select this component when automotive certification is mandatory. Choose based on the 8A holding current requirement. Consider the low voltage rating for appropriate application scope. Evaluate the radial lead form factor against available board space constraints.

Part Context

This part belongs to the Bourns MF-RG series of PTC resettable fuses. The series is characterized by its automotive qualification and compact physical footprint. It serves as a reusable alternative to traditional one-time fuses in critical vehicle systems.

Replacement Considerations

Direct substitutes include other MF-RG series variants with matching electrical ratings. Verify pin compatibility and thermal performance before substitution.
