Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix designation when ordering, as variants such as N13SP2R5M-F may indicate different packaging or manufacturing status. Confirm that the selected part number matches the required electrical specifications for the target circuit design. Cross-reference official manufacturer documentation to ensure compliance with current production statuses and availability constraints before finalizing procurement plans.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on its 2.5 Ohm initial resistance and 6 A current handling capability relative to the system's peak inrush requirements. Ensure the thermal environment allows for adequate heat dissipation given the 3 W power rating. Verify that the 13 mm body size and 7.5 mm lead pitch fit within the designated PCB footprint constraints without interfering with adjacent components.

Inrush Current Limiters (ICL) Part Context

This part belongs to the YAGEO SP series of NTC thermistors, which are specialized for inrush current limiting duties. The series offers various resistance and current ratings to suit different power levels. These components serve as critical passive elements in protecting downstream electronics from transient overcurrent conditions common in industrial and consumer power systems.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes include other NTC inrush limiters with matching 2.5 Ohm resistance and 6 A current ratings. Equivalent parts must maintain similar physical dimensions and lead spacing for board compatibility. Verify thermal performance curves to ensure comparable energy absorption capabilities during surge events.
