Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix 'F' against the manufacturer's latest datasheet to confirm packaging details and compliance status. Confirm that the 1.5 Ohm resistance value aligns with the target circuit's peak current requirements. Ensure the 8 A current rating exceeds the system's maximum inrush peak. Check for any end-of-life notifications or obsolescence warnings prior to final design approval.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 1.5 Ohm initial resistance is required to limit charging currents in capacitive loads. The 8 A rating must accommodate the specific peak current of the application without thermal failure. Consider the 18 mm diameter for adequate heat dissipation and physical clearance on the PCB. Verify that the 4 W power rating is sufficient for the duty cycle of the inrush events.
