0ZSA0120FF1E

Ptc Resettable Fuses Overview

The 0ZSA0120FF1E is a polymeric PTC resettable fuse from the Bel Fuse 0ZSA series, designed for strap mounting. It features axial leads and operates with a hold current of 1.2 A and a trip current of 2.4 A. The device supports a maximum voltage of 15 VDC and offers a maximum fault current rating of 100 A. Its initial resistance is 100 mOhms, with a power dissipation of 1.9 W. The component functions within a temperature range of -40°C to +85°C.

Ptc Resettable Fuses Feature Summary

• Utilizes polymeric positive temperature coefficient technology for automatic circuit protection
• Designed for direct strap mounting via axial leads
• Provides reusable overcurrent protection without manual replacement

Ptc Resettable Fuses Applications

• Battery pack protection in portable electronics
• Low-voltage DC circuit protection in automotive systems
• Overcurrent safeguarding in telecommunications equipment

Ptc Resettable Fuses Procurement Notes

Verify that the specific part number matches the required electrical parameters, particularly the 15V voltage rating and 1.2A hold current, as these are critical for low-voltage applications. Confirm the axial lead configuration is compatible with the intended strap mounting method on the target PCB or assembly. Ensure compliance with RoHS directives if required by the end product specifications.

Ptc Resettable Fuses Selection Notes

Select this component when a low-profile, strap-mountable solution is required for circuits operating at 15VDC or lower. The 1.2A hold current makes it suitable for moderate load protection where space constraints prevent through-hole or surface-mount alternatives. Consider the 100A max fault current capability for robust short-circuit protection in battery-powered designs.

Ptc Resettable Fuses Part Context

This device belongs to the 0ZSA series of resettable fuses, which are specialized for strap mounting applications. Unlike standard radial or surface-mount PTCs, the 0ZSA series utilizes axial leads to facilitate secure attachment directly to busbars or terminals, making it ideal for high-current density connections in compact enclosures.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes within the same series include 0ZSA0090FF1E (0.9A) and 0ZSA0200FF1E (2.0A). When replacing, ensure the new part maintains the 15VDC maximum voltage rating and axial lead format to preserve mechanical and electrical compatibility.
