Inrush Current Limiters (ICL) Procurement Notes

Verify the specific thermal and electrical requirements of your application against the datasheet parameters before ordering. Confirm that the steady-state current rating of 2.5 A aligns with your system's operational limits. Ensure the physical dimensions fit within the designated PCB footprint. Check for any specific packaging or handling requirements mandated by your manufacturing process.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 30 Ohm cold resistance is required to limit inrush current effectively. The 2.5 A steady-state rating determines the continuous load capacity. Consider the 15.50 mm diameter for spatial constraints on the printed circuit board. Evaluate the thermal environment to ensure the thermistor operates within its safe temperature range during sustained use.
