Inrush Current Limiters (ICL) Procurement Notes

Verify the specific datasheet version on the TDK Electronics website, as product information may be updated. Confirm that the 15 Ohm resistance and 4.4 A current rating align with your system's thermal and electrical requirements. Ensure the lead spacing matches your PCB footprint design before finalizing procurement.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 15 Ohm nominal resistance is required to limit initial charging currents. The 4.4 A steady-state current capacity determines the maximum operational load. Consider the 16 mm diameter for available board space and the leaded package style for through-hole mounting applications requiring reliable mechanical fixation.
