Ptc Resettable Fuses Procurement Notes

Verify the specific package dimensions and termination type against your PCB footprint requirements before ordering. Confirm that the 24VDC rating aligns with your system's maximum operating voltage. Ensure the hold current of 2A meets the continuous load requirements without nuisance tripping during normal operation.

Ptc Resettable Fuses Selection Notes

Select this component when space constraints require a surface mount form factor rather than through-hole options. Choose based on the 2A hold current and 24VDC limit to ensure compatibility with low-voltage automotive or portable applications. Consider the thermal environment to guarantee reliable performance within the specified -40°C to +85°C operating range.

Ptc Resettable Fuses Part Context

This part belongs to the AHS series of Automotive High Temperature SMD fuses from Littelfuse. The series is engineered specifically for harsh automotive environments, offering robust protection against overcurrent conditions while maintaining a small physical profile suitable for modern high-density electronic assemblies.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include other AHS series variants with similar electrical ratings, such as the AHS100F/24-2 for lower current needs. Cross-reference with SMDC series parts if higher current capacity is required, ensuring voltage and package compatibility are maintained.
