0ZSC0550FF1E

Ptc Resettable Fuses Overview

The Bel Fuse 0ZSC0550FF1E is a strap-mount PPTC resettable fuse designed for circuit protection. It features an axial termination style and belongs to the 0ZSC series. Key electrical parameters include a hold current of 5.5 A, a trip current of 10.5 A, and a maximum voltage rating of 20 VDC. The device exhibits a low resistance of 22 mOhms and functions as a slow blow fuse. It is supplied in bulk packaging.

Ptc Resettable Fuses Feature Summary

Provides overcurrent protection through automatic reset functionality upon cooling after fault removal.
Utilizes a strap mount installation style with axial leads for secure physical attachment.
Designed for high-current applications requiring a low impedance path during normal operation.

Ptc Resettable Fuses Applications

Protection of power supply inputs in electronic equipment
Overcurrent safeguarding in automotive circuits
Battery pack protection systems

Ptc Resettable Fuses Procurement Notes

Verify that the required hold current of 5.5 A aligns with the system's operational load to prevent nuisance tripping. Confirm the maximum voltage rating of 20 VDC is sufficient for the circuit environment. Ensure the strap mount mechanical interface matches the assembly design. Check RoHS compliance requirements against project specifications before finalizing procurement.

Ptc Resettable Fuses Selection Notes

Select this component when a high current capacity of 5.5 A is necessary within a low voltage system limited to 20 VDC. The low resistance value minimizes power loss during normal operation. Consider the strap mount form factor if space constraints or specific mounting hardware dictate the use of axial leads rather than surface mount or radial configurations.

Ptc Resettable Fuses Part Context

This part belongs to the 0ZSC series of resettable fuses from Bel Fuse. The series is characterized by its ability to handle significant currents while maintaining a compact profile suitable for various industrial and consumer electronics applications. The specific model indicates a 5.5 A hold current variant within this product line.
