Ptc Resettable Fuses Procurement Notes

Verify that the specific suffix 'S' aligns with the required tape-and-reel or bulk configuration as defined in the official Littelfuse datasheet. Confirm that the 16 VDC voltage rating and 6 A hold current meet the target circuit requirements. Ensure the operating temperature range covers the intended environmental conditions. Cross-reference the package dimensions against the PCB footprint design.

Ptc Resettable Fuses Selection Notes

Select this component when a self-resetting overcurrent solution is preferred over traditional fuses to reduce maintenance. The 6 A hold current supports moderate load currents while the 10.8 A trip point provides clear fault detection. The low resistance value minimizes power loss during normal operation. Consider the thermal environment, as ambient temperature affects the effective current carrying capacity.
