0ZRC0055FF2E

Ptc Resettable Fuses Overview

The Bel Fuse 0ZRC0055FF2E is a radial leaded polymeric resettable fuse (PPTC) from the 0ZRC series. It features a holding current of 550 mA and a trip current of 1.2 A, with a maximum voltage rating of 90 VAC/VDC. The device has a resistance of 65 mOhms and an interrupting rating of 50 A. It operates within a temperature range of -40°C to +85°C. The component measures 7.4 mm in diameter and 3.1 mm in height, designed for PCB mounting.

Ptc Resettable Fuses Feature Summary

• Polymeric positive temperature coefficient construction for automatic circuit protection
• Radial leaded package design for through-hole PCB integration
• Self-resetting functionality eliminates need for manual replacement after fault clearance

Ptc Resettable Fuses Applications

• Overcurrent protection for portable electronic devices
• Protection circuits in consumer audio and video equipment
• Battery pack safeguarding in mobile applications

Ptc Resettable Fuses Procurement Notes

Verify that the specific suffix FF2E corresponds to the tape and reel packaging configuration as documented in official manufacturer datasheets. Confirm that the 90V AC/DC rating aligns with the target circuit requirements. Ensure compliance with RoHS directives by checking the latest product certificates provided by Bel Fuse.

Ptc Resettable Fuses Selection Notes

Select this component when a low-profile radial PTC fuse is required for 90V systems. The 550 mA holding current suits moderate load protection needs. Consider the 65 mOhms initial resistance for minimal voltage drop impact. Evaluate thermal derating requirements based on the -40°C to +85°C operating range.

Ptc Resettable Fuses Part Context

This part belongs to the Bel Fuse 0ZRC series of radial PTC resettable fuses. These components are engineered for compact electronics where space constraints limit the use of larger axial or surface-mount devices. The series provides reliable overcurrent protection with a small form factor suitable for dense PCB layouts.

Ptc Resettable Fuses Replacement Considerations

Cross-reference with other 0ZRC series variants having matching 550 mA hold current and 90V ratings. Verify dimensional compatibility for existing PCB footprints before substitution.
