Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix D15 indicates the 17.5mm diameter variant when sourcing replacements. Confirm that the required steady-state current rating of 7 A aligns with the application's operational limits. Ensure the supplier provides documentation confirming compliance with RoHS3 standards prior to final procurement authorization.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 3 Ohm initial resistance is required to limit startup currents. The 7 A steady-state rating determines the continuous load capacity. The 17.5 mm package size must fit within the available PCB area. Verify that the B value characteristics match the thermal calibration requirements of the target system design.
