FSMD035-0805-R

Ptc Resettable Fuses Overview

The FSMD035-0805-R is a surface-mount polymeric positive temperature coefficient (PPTC) resettable fuse manufactured by Fuzetec Technology. It belongs to the FSMD series, designed for overcurrent protection in compact electronic assemblies. The device utilizes a polymer composite that increases resistance significantly upon excessive current flow, thereby limiting fault current. It features an 0805 package footprint and is rated for a maximum voltage of 8V. The component provides reliable circuit protection against short circuits and overloads without requiring replacement after tripping.

Ptc Resettable Fuses Feature Summary

• Polymer-based self-resetting mechanism eliminates the need for manual replacement after fault events
• Compact 0805 surface-mount form factor enables integration into space-constrained printed circuit boards
• Thermal response characteristics allow operation within standard ambient temperature ranges

Ptc Resettable Fuses Applications

• Portable consumer electronics battery protection
• USB peripheral interface circuits
• Low-voltage data line surge suppression

Ptc Resettable Fuses Procurement Notes

Verify the specific hold current and trip current ratings against the target application's operating parameters. Confirm the voltage rating aligns with the system supply. Ensure the peak pulse current capability exceeds potential inrush requirements. Check RoHS compliance status if required by regional regulations. Validate the package dimensions match the PCB land pattern design.

Ptc Resettable Fuses Selection Notes

Select this component based on the required holding current relative to the normal operating load. Consider the maximum operating voltage of the protected circuit. Evaluate the time-current characteristics to ensure adequate protection speed. Assess the physical size constraints of the assembly. Verify compatibility with automated pick-and-place manufacturing processes.

Ptc Resettable Fuses Part Context

This part is part of Fuzetec's FSMD series of resettable fuses.
