0ZRA0500FF2D

Ptc Resettable Fuses Overview

The Bel Fuse 0ZRA0500FF2D is a radial lead PPTC resettable fuse designed for circuit protection. It features a hold current of 5 A and a trip current of 8.5 A, with a maximum voltage rating of 16 VDC. The device has a post-trip resistance of 44 Ohms and supports a maximum fault current of 100 A. It operates within a temperature range of -40°C to +85°C and exhibits a trip time of 3.6 seconds under specified conditions.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit interruption upon overcurrent events using polymer positive temperature coefficient technology.
• Offers reliable protection in radial lead configurations suitable for through-hole mounting applications.

Ptc Resettable Fuses Applications

• Overcurrent protection for low-voltage DC power distribution lines
• Protection of portable electronic devices and battery packs
• Circuit safeguarding in consumer electronics and peripheral equipment

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix FF2D against official Bel Fuse documentation to confirm exact package dimensions and lead configuration. Ensure that the 16 VDC rating aligns with the system's maximum operating voltage. Confirm RoHS compliance status and check for any recent manufacturing changes or obsolescence notices directly from the manufacturer before finalizing procurement plans.

Ptc Resettable Fuses Selection Notes

Select this component when a 5 A hold current and 16 VDC rating are required for radial PPTC applications. Consider the 44 Ohms post-trip resistance impact on downstream circuitry during fault conditions. Evaluate the 3.6-second trip time against the sensitivity requirements of protected loads. Compare against higher voltage series if system voltages exceed 16 VDC.

Ptc Resettable Fuses Part Context

This part belongs to the 0ZRA series of radial PPTC resettable fuses from Bel Fuse. The series is characterized by its compact radial design and suitability for general-purpose circuit protection. It complements other Bel Fuse offerings like the 0ZRS automotive-grade series and surface-mount options such as the 0ZCF series.

Ptc Resettable Fuses Replacement Considerations

The 0ZRA0500FF1E is a verified substitute within the same series offering identical electrical ratings including 5 A hold current and 16 VDC max voltage. Verify mechanical footprint compatibility between the FF1E and FF2D suffixes before substitution.
