Inrush Current Limiters (ICL) Procurement Notes

Verify the specific B-parameter value against the latest official datasheet, as variations exist within the ICL family. Confirm that the 12 A steady-state current rating aligns with your system's operational requirements. Ensure the 1.5 Ohm resistance at 25°C meets the design specifications for inrush limiting. Check RoHS3 compliance status if required by your manufacturing standards.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 1.5 Ohm initial resistance is required to limit peak inrush currents effectively. The 12 A continuous current rating suits moderate-to-high power applications. Consider the 19 mm diameter for adequate heat dissipation. Verify compatibility with existing PCB footprint dimensions, specifically the 7.50 mm lead spacing. Evaluate thermal performance under worst-case ambient conditions.
