Inrush Current Limiters (ICL) Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm lead time and availability status. Ensure that the selected variant matches the required mechanical dimensions and electrical ratings for the target application. Cross-reference the datasheet specifications to validate compliance with safety standards such as UL approval before finalizing procurement orders.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the required steady-state current of 7 A and the 14 Ohm resistance value. Consider the 75 Joule energy rating when designing for capacitive loads or transformer inrush scenarios. Ensure the 22 mm diameter fits the available PCB space and verify that the radial kinked lead style aligns with the assembly process requirements.

Inrush Current Limiters (ICL) Part Context

This part belongs to the SL22 series of inrush current limiters from Vishay Ametherm. The series provides various resistance and current combinations for different power levels. The SL2214007A specifically addresses mid-range current applications requiring moderate resistance values. It is distinct from higher current variants like the SL221R020 or lower current options within the same family.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes include the SL2214007 without the 'A' suffix if mechanical compatibility is confirmed. Other Vishay Ametherm parts with identical 14 Ohm resistance and 7 A rating may be considered, provided they match the 22 mm diameter and kinked lead specifications.
