Inrush Current Limiters (ICL) Procurement Notes

Verify the exact electrical parameters against the manufacturer's official datasheet prior to integration, as this part number indicates a customized specification within the SL22 series. Confirm that the 20 Ohm resistance and 7 A current ratings align with your system's thermal and surge management requirements. Ensure compatibility with the specified 22 mm form factor and lead style for your printed circuit board layout constraints.

Inrush Current Limiters (ICL) Selection Notes

Select this component when standard catalog values do not meet specific inrush current or physical dimension requirements. The 20 Ohm resistance provides effective surge suppression for circuits drawing up to 7 A continuously. Consider the thermal dissipation characteristics and the 25% resistance tolerance when designing the surrounding circuitry to ensure consistent performance across varying ambient temperatures and manufacturing batches.
