Inrush Current Limiters (ICL) Procurement Notes

Verify the specific ordering suffix 'B' against the manufacturer's official datasheet to confirm dimensional or material specifications. Ensure the selected variant matches the required steady-state current and resistance tolerance for the target circuit design. Cross-reference the RoHS compliance status with the latest documentation provided by Vishay / Ametherm prior to finalizing procurement orders.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the required nominal resistance value and the maximum continuous current rating of the application. Consider the thermal environment, as the steady-state current rating is defined up to 65°C ambient temperature. Verify that the physical package size and lead pitch are compatible with the printed circuit board layout constraints.
