0ZRR0050FF2E

Ptc Resettable Fuses Overview

The Bel Fuse 0ZRR0050FF2E is a PPTC resettable fuse from the 0ZRR series, designed for overcurrent protection in electronic circuits. It features a holding current of 500 mA and a trip current of 1 A. The device supports a maximum voltage of 60 VDC with a maximum fault current rating of 40 A. Its initial resistance is 1.17 Ohms. Operating within a temperature range of -40°C to +85°C, it utilizes a radial leaded package measuring 7.9 mm in diameter and 3.1 mm in height.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit recovery after fault conditions without manual replacement
• Offers high fault current interruption capability up to 40 A
• Designed for slow-blow response characteristics to tolerate transient surges

Ptc Resettable Fuses Applications

• Overcurrent protection for portable electronic devices
• Protection of peripheral interfaces such as USB and HDMI ports
• Battery pack safeguarding in consumer electronics

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix FF2E corresponds to the required reel packaging configuration. Confirm that the 60 VDC rating aligns with the target circuit's operating voltage. Ensure the radial leaded form factor fits the designated PCB footprint. Cross-reference the 500 mA holding current against the application's continuous load requirements to prevent nuisance tripping during normal operation.

Ptc Resettable Fuses Selection Notes

Select this component when a higher voltage rating than standard low-voltage SMD fuses is required. The radial leaded construction facilitates through-hole mounting on boards where surface area is limited or mechanical robustness is prioritized. Consider the 1.17 Ohm resistance impact on power loss if the application involves significant continuous current flow near the holding limit.

Ptc Resettable Fuses Part Context

This part belongs to the Bel Fuse 0ZRR family of radial leaded PPTC devices. These components are engineered for general-purpose overcurrent protection in environments requiring reliable thermal switching. The series provides a cost-effective alternative to traditional fusible links by enabling repeated use after fault clearance.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include other 0ZRR series variants with matching electrical ratings, such as 0ZRR0030FF2E for lower current applications. Verify that any replacement maintains the same 60 VDC maximum voltage and radial leaded package dimensions to ensure physical compatibility.
