0ZSC0190FF1E

Ptc Resettable Fuses Overview

The Bel Fuse 0ZSC0190FF1E is a PPTC resettable fuse from the 0ZSC series, designed for strap mount installation with axial termination. It features a holding current of 1.9 A and a trip current of 3.8 A. The device supports a maximum voltage of 20 VDC and exhibits a resistance of 45 mOhms. Classified as a slow blow fuse, it provides overcurrent protection in electronic circuits.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit protection through self-resetting polymer positive temperature coefficient technology
• Designed for secure attachment via strap mount installation style with axial leads
• Offers reliable overcurrent interruption capabilities characterized by slow blow response behavior

Ptc Resettable Fuses Applications

• Consumer electronics power supply input protection
• Portable device battery circuit safeguarding
• Low voltage automotive accessory circuit monitoring

Ptc Resettable Fuses Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required mounting configurations and lead styles. Confirm that the maximum voltage rating aligns with the system operating conditions. Check RoHS compliance status if environmental regulations apply to the final assembly. Ensure the holding current meets the continuous operational load requirements without nuisance tripping during normal use.

Ptc Resettable Fuses Selection Notes

Select this component when a low profile resettable fuse is needed for circuits operating at 20 VDC or less. The 1.9 A holding current suits applications requiring moderate current capacity with fast thermal response characteristics. Consider the 45 mOhms resistance for minimal voltage drop impact in sensitive signal paths. Evaluate the strap mount option for robust mechanical fixation in high vibration environments.

Ptc Resettable Fuses Part Context

This part belongs to the 0ZSC series of resettable fuses manufactured by Bel Fuse. The series focuses on compact, surface-mountable solutions for modern electronic designs. These components replace traditional fusible links by offering reusable protection against overcurrent events while maintaining a small footprint suitable for dense PCB layouts.

Ptc Resettable Fuses Replacement Considerations

Consult official substitution guides for equivalent parts within the same voltage and current ratings. Verify that alternative components match the 20 VDC maximum voltage and similar trip current thresholds. Ensure mechanical mounting compatibility if replacing in existing strap-mounted assemblies.
