Inrush Current Limiters (ICL) Procurement Notes

Verify the specific manufacturer part number against official Vishay documentation to ensure compatibility with design requirements. Confirm that the 5 Ohm resistance and 3 A current rating align with the target circuit's electrical specifications. Check for any updated regulatory compliance status or package variations before finalizing procurement orders.

Inrush Current Limiters (ICL) Selection Notes

Select this component when the application requires limiting initial surge currents in low-power AC circuits rated up to 230 VAC. Ensure the steady-state operating current does not exceed the 3 A continuous rating. Consider the physical footprint constraints regarding the 10 mm diameter and 7.8 mm lead spacing for PCB layout planning.
