Inrush Current Limiters (ICL) Procurement Notes

Verify the specific ordering suffix, as 'N25SP020L' and 'N25SP020L-F' may denote different packaging or compliance statuses. Confirm that the 20-ohm resistance value aligns with the circuit's inrush limiting requirements. Ensure the 5 A current rating exceeds the peak operational load to prevent thermal failure.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on its 20-ohm initial resistance to limit peak charging currents effectively. The 6.5 W power rating must accommodate the energy dissipated during the inrush event. Verify that the 25 mm diameter fits the available PCB footprint and that the radial leads match the mounting hole configuration.

Inrush Current Limiters (ICL) Part Context

This part belongs to the YAGEO SP series of NTC thermistors designed specifically for inrush current limiting. These components are engineered to protect sensitive electronic equipment from high transient currents. The series offers various resistance values to suit different power levels and application constraints.

Inrush Current Limiters (ICL) Replacement Considerations

Cross-reference other YAGEO NTC thermistors with similar 20-ohm resistance and 5 A current ratings. Ensure any substitute matches the 25 mm diameter and radial lead spacing for mechanical compatibility. Verify equivalent power dissipation capabilities.
