FSMD160-16R

Ptc Resettable Fuses Overview

The FSMD160-16R is a surface-mountable PTC resettable fuse from the FSMD1812 series. It features a concave shape within an 1812 (4532 Metric) package, measuring 4.55mm in length, 3.24mm in width, and a maximum thickness of 1.35mm. The component has a rated voltage of 16V and a maximum current rating of 100A. Its hold current is specified at 1.6A, with a trip current of 3.2A.

Ptc Resettable Fuses Feature Summary

• Surface mountable design suitable for automated assembly processes
• Concave physical profile accommodates specific board clearance requirements
• Polymeric positive temperature coefficient material provides overcurrent protection

Ptc Resettable Fuses Applications

• Portable electronic device circuit protection
• Battery pack overcurrent safeguarding
• Interface port surge suppression

Ptc Resettable Fuses Procurement Notes

Verify the exact datasheet version when sourcing, as manufacturer documentation may vary slightly between RFE/Fuzetec and Fuzetec Technology Co., Ltd. labels. Confirm the concave package orientation matches your PCB footprint design to ensure proper solder joint formation and thermal performance during reflow processes.

Ptc Resettable Fuses Selection Notes

Select this component when space constraints require an 1812 footprint with a low-profile concave geometry. Ensure the operating voltage does not exceed 16V and that the expected fault current remains below the 100A maximum limit. Validate that the 1.6A hold current aligns with normal circuit operation to prevent nuisance tripping.

Ptc Resettable Fuses Part Context

This part belongs to the FSMD1812 series of surface mountable PTC resettable fuses. The series offers various current ratings within the same 1812 package form factor, allowing designers to standardize footprints across different product lines while adjusting protection levels based on specific current requirements.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes must match the 1812 concave package, 16V rating, and 1.6A hold current specifications. Cross-reference with other manufacturers offering identical dimensional and electrical characteristics to ensure mechanical compatibility and equivalent thermal response times.
