FSMD016-1206-R

Ptc Resettable Fuses Overview

The FSMD016-1206-R is a surface-mount polymeric positive temperature coefficient (PPTC) resettable fuse manufactured by Fuzetec. Designed for high-density circuit protection, this component operates within a voltage range up to 48V and supports a maximum current of 100A. The device maintains a holding current of 160mA and trips at 480mA. It features a low initial resistance of 1.3 ohms and a trip resistance of up to 5.5 ohms. With a power dissipation rating of 600mW and an action time of 200ms, it functions reliably between -40°C and +85°C. The physical dimensions are 3.5mm in length, 1.8mm in width, and 0.85mm in height.

Ptc Resettable Fuses Feature Summary

• Solid-state construction providing faster trigger times and lower resistance compared to standard SMD devices.
• RoHS compliant and halogen-free composition suitable for environmentally regulated manufacturing processes.
• Compact 1206 surface-mount footprint designed specifically for integration into dense PCB layouts.

Ptc Resettable Fuses Applications

• Protection circuits for high-density printed circuit boards.
• Overcurrent safeguarding in portable electronic devices.
• Interface protection for data and communication lines.

Ptc Resettable Fuses Procurement Notes

Verify the specific electrical parameters against the official datasheet before implementation. Confirm that the 160mA holding current aligns with the target circuit's operational requirements. Ensure the 48V maximum voltage rating exceeds the system's peak operating voltage. Check compliance with RoHS and halogen-free standards if required by project specifications.

Ptc Resettable Fuses Selection Notes

Select this component when space constraints require a 1206 package size for overcurrent protection. Choose this part if the application demands a solid-state solution with rapid response characteristics. Consider the 160mA holding current limit to ensure normal operation does not cause nuisance tripping. Verify thermal management capabilities given the 600mW power dissipation rating under fault conditions.

Ptc Resettable Fuses Part Context

This component belongs to the FSMD series of self-resetting fuses from Fuzetec. The series utilizes polymeric technology to provide reusable overcurrent protection. The 1206 designation indicates the standardized surface-mount package dimensions. This family of components serves as an alternative to traditional fusible links in modern electronics.
