0ZRN0400FF1E

Ptc Resettable Fuses Overview

The 0ZRN0400FF1E is a radial PPTC resettable fuse from the Bel Fuse 0ZRN series, designed for PCB mount applications. It features a hold current of 4 A and a trip current of 8 A, with a maximum voltage rating of 16 VDC. The device exhibits an initial resistance of 35 mOhms and supports a maximum fault current of 100 A. Operating within a temperature range of -40°C to +125°C, it measures 13.8 mm in length, 9.5 mm in width, and 3 mm in height, utilizing a radial lead configuration.

Ptc Resettable Fuses Feature Summary

• Provides overcurrent protection through automatic recovery after fault conditions clear
• Complies with AEC-Q200 automotive qualification standards for reliability
• Utilizes polymer positive temperature coefficient technology for slow-blow response

Ptc Resettable Fuses Applications

• Automotive electronic circuit protection
• Low-voltage DC power line safeguarding
• PCB-mounted component overcurrent defense

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix FF1E against official Bel Fuse documentation to confirm package type and lead finish specifications. Ensure the selected variant matches the required 16 VDC rating and 4 A hold current for the target application. Cross-reference the AEC-Q200 certification status if automotive compliance is mandatory. Confirm dimensional tolerances align with the PCB footprint design before finalizing procurement orders.

Ptc Resettable Fuses Selection Notes

Select this component when a 4 A hold current and 16 VDC maximum voltage are required for low-profile automotive or industrial circuits. The radial package suits through-hole mounting where space constraints allow for the specified dimensions. Consider the 125°C maximum operating temperature for high-heat environments. Evaluate the 35 mOhms initial resistance impact on circuit efficiency during normal operation.

Ptc Resettable Fuses Part Context

This part belongs to the Bel Fuse 0ZRN series of radial PPTC resettable fuses. The series is engineered for automotive and general electronics applications requiring robust overcurrent protection. Components in this family share common polymer construction and slow-blow characteristics, differentiated primarily by their electrical ratings and physical dimensions.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include other 0ZRN series variants with matching 4 A hold current and 16 VDC ratings, such as 0ZRN0400FF1A, provided package and lead specifications are compatible.
