Inrush Current Limiters (ICL) Procurement Notes

Verify the specific beta constant against official datasheets, as variations exist within the ICL family (e.g., 3100K vs 3400K). Confirm lead type and physical dimensions match design requirements. Ensure RoHS compliance status is checked for the specific manufacturing batch. Cross-reference the part number suffix to confirm exact tolerance and beta definition codes.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the required 12 Ohm resistance and 30 mm body size. Evaluate the 9 A steady-state current rating against circuit demands. Consider the 3400 K beta value for accurate thermal calculations. Compare with other ICL variants if different resistance or current ratings are needed. Verify package style matches assembly processes.
