Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix 'A' against the manufacturer datasheet to confirm exact physical dimensions and lead specifications. Ensure the application environment does not exceed the thermal limits defined in the official documentation. Cross-reference the UL and CSA certification marks if regulatory compliance is required for the final assembly.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 10 Ohm cold resistance and 3A continuous current handling are required. Consider the 10mm diameter for available board space. Evaluate the energy absorption requirements against the specific circuit's capacitive load to ensure adequate surge protection without unnecessary thermal stress during normal operation cycles.

Inrush Current Limiters (ICL) Part Context

This part belongs to the SL10 series of inrush current limiters manufactured by Vishay Ametherm.
