Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix 'F' against the manufacturer's latest datasheet to confirm compliance with RoHS directives and halogen-free requirements. Ensure the ordering quantity matches the specified bulk packaging configuration. Confirm that the 15 A current rating aligns with the system's peak load requirements before finalizing procurement.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 1.5 Ohm initial resistance is required for high-current inrush limiting. The 6.5 W power rating supports significant energy dissipation during startup transients. Verify that the 29 mm diameter fits the available board space and that the radial lead pitch matches the target PCB footprint design constraints.

Inrush Current Limiters (ICL) Part Context

This part belongs to the YAGEO SP series of NTC thermistors. These components are engineered specifically for protecting sensitive electronic components from high surge currents during power-up phases. The series offers various resistance values to suit different circuit impedance requirements while maintaining consistent physical dimensions for standardized mounting.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes include other YAGEO SP series variants such as N25SP001M-F or N25SP4R7M-F if resistance adjustments are permissible. Cross-manufacturer replacements require matching the 1.5 Ohm resistance, 15 A current rating, and 29 mm diameter to ensure mechanical and electrical compatibility.
