Procurement Notes

Verify the specific suffix J against official KEMET documentation to confirm exact electrical tolerances and physical dimensions. Ensure the procurement channel provides authentic components with valid RoHS compliance data. Cross-reference the manufacturer part number SC-18-E15J with authorized distributor listings to avoid counterfeit products. Confirm that the through-hole pin spacing matches the target PCB layout requirements before finalizing orders.

Selection Notes

Select this component when high current handling and low DC resistance are critical for power line filtering. The 1.5 mH inductance value targets specific noise frequencies at 10 kHz. Verify that the 18 A rating exceeds the peak load currents of the application. Ensure the vertical package dimensions fit within the available enclosure space. Confirm compatibility with standard through-hole assembly processes.

Part Context

This component is part of the KEMET SC-J series of common mode chokes designed for AC line filtering. The series offers various inductance values and current ratings to suit different power electronics requirements. The SC-18 designation indicates a specific current and size class within this family. These filters are engineered for robust performance in demanding industrial and commercial environments.

Replacement Considerations

Consult official KEMET substitution guides for verified alternatives. Ensure any replacement maintains identical inductance, current rating, and physical footprint. Verify that substitute components meet the same thermal and voltage specifications.
