Ptc Resettable Fuses Procurement Notes

Verify the specific suffix YR indicates reel packaging when ordering. Confirm RoHS compliance status matches project requirements. Ensure the 0805 package dimensions align with the PCB footprint design. Check lead times as manufacturing schedules may vary. Validate that the 6V rating meets the circuit's operational voltage needs.

Ptc Resettable Fuses Selection Notes

Select this part when low initial resistance is critical for signal integrity or efficiency. The 1.75 A hold current suits moderate load protection needs. Consider the 0805 size for space-constrained designs compared to larger packages. Verify that the 6V rating is sufficient for the specific application voltage. Evaluate thermal dissipation capabilities within the enclosure.

Ptc Resettable Fuses Part Context

This component belongs to Littelfuse's LoRho series, which specializes in low-resistance PPTC devices. The series targets applications where standard PTCs cause excessive voltage drop. The 0805L175SLYR represents a balance between current handling and physical size. It complements other LoRho variants offering different current ratings in similar footprints.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include other 0805 PPTCs with matching 1.75 A hold current and 6V rating. Verify resistance values to ensure equivalent performance. Check package compatibility for direct replacement. Littelfuse offers other LoRho parts with adjusted currents for similar form factors.
