SCT39XV-140-S1R6A014JH

Overview

The KEMET SCT39XV-140-S1R6A014JH is a three-line common mode choke designed for automotive applications, certified to AEC-Q200 standards. It features an inductance of 1.46 mH at 100 kHz and supports a continuous DC current rating of 14 A. The component has a typical DC resistance of 7.87 mΩ and withstands up to 1 kV AC/DC voltage. Operating temperatures range from -40°C to +150°C, with a through-hole mounting style.

Feature Summary

• Three-phase configuration for balanced noise suppression
• Automotive-grade reliability via AEC-Q200 certification
• High current handling capability of 14 A
• Low DC resistance for efficient power transmission

Applications

• AC-DC power supplies in electric vehicles
• On-board charger (OBC) input filtering
• Traction inverter EMI suppression
• General automotive high-current DC bus protection

Procurement Notes

Verify the specific suffix against official KEMET documentation to confirm pinout and tolerance variations. Ensure the procurement channel provides traceability for AEC-Q200 compliance. Confirm that the package dimensions match the target PCB footprint before ordering. Check for any recent lifecycle status updates or obsolescence notices directly from the manufacturer.

Selection Notes

Select this component when three-phase common mode noise attenuation is required in high-current automotive environments. The 14 A rating suits main power lines, while the 1.46 mH inductance targets specific frequency ranges. Compare thermal performance requirements against the 150°C operating limit. Consider physical size constraints relative to other SCT series variants.

Part Context

This part belongs to the KEMET SCT series of automotive common mode chokes. These components are engineered specifically for harsh automotive electrical environments. The series emphasizes high saturation current and low impedance characteristics. It complements other passive components in vehicle power distribution networks.

Replacement Considerations

Check KEMET's official substitution guide for equivalent SCT series parts with matching inductance and current ratings. Verify that any alternative maintains AEC-Q200 certification if automotive use is required. Ensure mechanical compatibility with existing through-hole mounting structures.
