Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix 'CT' against the manufacturer datasheet to confirm if it denotes a custom configuration or specific packaging variation distinct from standard bulk parts. Ensure the ordering part number matches the exact electrical requirements and physical dimensions required by the target application design.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the 7 Ohm initial resistance and 10 A current rating to match the specific inrush energy profile of the load. Consider the 22 mm form factor for adequate thermal mass and mechanical stability within the available PCB real estate constraints.

Inrush Current Limiters (ICL) Part Context

This part belongs to the SL22 series of inrush current limiters manufactured by Vishay / Ametherm. The series offers various resistance and current combinations within a standardized 22 mm package size, allowing designers to scale protection levels while maintaining consistent mechanical footprint across different power supply designs.

Inrush Current Limiters (ICL) Replacement Considerations

Compatible substitutes include other 22 mm NTC inrush limiters with similar 7 Ohm resistance and 10 A current ratings, such as the SL227R010. Verify that alternative parts meet the same voltage ratings and UL certification standards before implementation.
