FEMTOSMDC008F-02

Ptc Resettable Fuses Overview

The Littelfuse FEMTOSMDC008F-02 is a surface-mount polymer positive temperature coefficient (PPTC) resettable fuse from the femtoASMD series. It provides overcurrent protection with a hold current of 80 mA and a trip current of 200 mA at a maximum voltage of 12 VDC. The device features a low resistance of 14 Ohms and can withstand a maximum fault current of 10 A. Designed for automotive applications, it meets AEC-Q200 qualification standards. The component operates within a temperature range of -40°C to +85°C and is housed in a compact 0603 package measuring 1.8 mm in length, 1 mm in width, and 0.85 mm in height.

Ptc Resettable Fuses Feature Summary

• Self-resetting functionality restores circuit operation after fault conditions without manual replacement
• AEC-Q200 qualified for reliability in harsh automotive environments
• Lead-free construction compliant with RoHS directives
• Compact surface-mount footprint suitable for high-density PCB layouts

Ptc Resettable Fuses Applications

• Automotive electronic circuits requiring AEC-Q200 compliance
• Overcurrent protection for sensitive integrated circuits

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix designation against official Littelfuse documentation to ensure correct electrical characteristics. Confirm that the required hold and trip currents align with the target circuit design parameters before procurement. Ensure compatibility with standard reflow soldering profiles for surface-mount assembly processes.

Ptc Resettable Fuses Selection Notes

Select this component when a low-voltage, small-footprint resettable fuse is required for automotive or industrial applications. The 80 mA hold current suits low-power signal lines. Verify that the 12 VDC rating matches the system voltage. Consider the 14 Ohm resistance impact on signal integrity if used in sensitive analog paths.

Ptc Resettable Fuses Part Context

This part belongs to the femtoASMD series, which offers smaller form factors compared to the ASMD and picoASMD families. These devices are designed to provide robust circuit protection while minimizing board space consumption. The series is specifically engineered to meet the stringent reliability requirements of modern automotive electronics.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include other femtoASMD variants with matching electrical ratings. Cross-reference with ASMDC series parts only if larger footprints are acceptable. Verify that any replacement maintains AEC-Q200 qualification if automotive use is intended.
