Inrush Current Limiters (ICL) Procurement Notes

Verify the specific ordering suffix 'A' matches the required mechanical dimensions and electrical tolerances. Confirm that the 10 Ohm resistance and 8 A current rating align with the system's peak load requirements. Ensure the 22 mm diameter fits within the designated PCB footprint and clearance constraints.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 10 Ohm initial resistance is required to manage inrush events up to 8 A. The 22 mm form factor suits applications needing higher energy absorption compared to smaller variants. Verify compatibility with standard radial lead PCB layouts and ensure the operating environment does not exceed thermal limits.
