FSMD010-0805-R

Ptc Resettable Fuses Overview

The FSMD010-0805-R is a surface mount PTC resettable fuse from the FSMD0805 series, designed for overcurrent protection in compact electronic assemblies. It features an 0805 (2012 Metric) concave package with dimensions of 0.085" L x 0.053" W and a maximum thickness of 0.039" (1.00mm). The component operates at a maximum voltage of 15V and maintains an initial resistance minimum of 700 mOhms. Post-trip resistance reaches a maximum of 6 Ohms, ensuring reliable circuit interruption and recovery capabilities.

Ptc Resettable Fuses Feature Summary

• RoHS compliant and halogen-free construction suitable for environmentally sensitive applications
• Concave surface mount design facilitates automated placement on high-density PCBs
• Self-resetting functionality provides reusable overcurrent protection without manual replacement

Ptc Resettable Fuses Applications

• High-density consumer electronics circuits
• Portable device power line protection
• Compact industrial control modules

Ptc Resettable Fuses Procurement Notes

Verify the specific voltage rating configuration, as datasheets indicate variations between 15V and 24V models within the same series prefix. Confirm packaging details, noting that some sources specify tape and reel quantities while others list bulk counts. Ensure the supplier documentation matches the required current rating and physical package tolerance for your assembly process.

Ptc Resettable Fuses Selection Notes

Select this component when space constraints require an 0805 footprint for overcurrent protection. Consider the 15V maximum operating voltage limit for low-voltage DC applications. Evaluate the post-trip resistance value against thermal management requirements to ensure adequate heat dissipation during fault conditions without damaging adjacent components.

Ptc Resettable Fuses Part Context

This part belongs to the FSMD0805 series of surface mountable PTC resettable fuses manufactured by RFE/Fuzetec. The series is characterized by its small form factor and compliance with environmental standards. It serves as a protective element in modern electronics where traditional fuses are impractical due to size or maintenance requirements.

Ptc Resettable Fuses Replacement Considerations

The FSMD010-0805-R may be substituted with other 0805 PTC fuses from different manufacturers provided they match the 15V rating, hold current specifications, and physical dimensions. Verify that alternative parts offer comparable trip times and post-trip resistance characteristics to maintain circuit safety performance.
