Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Transformer primary circuits
• Capacitive load protection

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific datasheet version to confirm the lead pitch dimension, as sources indicate variations between 2.74 mm and 3 mm. Ensure the selected variant matches the required 16 A current rating and 0.5 Ohm resistance value for the target application circuit.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a low-resistance path is needed for high-current applications up to 16 A. The 22 mm diameter provides sufficient thermal mass for moderate surge energy. Verify that the 3 mm lead spacing fits the target PCB footprint constraints before finalizing the design.

Inrush Current Limiters (ICL) Part Context

This part belongs to the SL22 series of NTC thermistors designed for general-purpose inrush current limiting. The series offers various resistance and current combinations within a standardized 22 mm package form factor, allowing for consistent mechanical integration across different power levels.

Inrush Current Limiters (ICL) Replacement Considerations

Cross-reference with Vishay Ametherm models sharing the 22 mm diameter and similar 0.5 Ohm resistance values. Ensure substitute parts meet the same 16 A current rating and UL certification requirements.
