Procurement Notes
Verify the specific part number SCT29XV-270-2R3A006JH against official KEMET documentation to confirm electrical ratings and package dimensions. Ensure compatibility with AEC-Q200 requirements if used in automotive contexts. Check for any recent manufacturing updates or obsolescence notices directly from the manufacturer before finalizing procurement plans.
Selection Notes
Select this component when high current capacity and robust automotive qualification are required. The 27 A rating and 120 µH inductance make it suitable for filtering in power stages where space allows for radial leads. Compare DCR values against system efficiency targets to ensure minimal voltage drop under load conditions.
Part Context
This component belongs to KEMET's SCT series of common mode chokes, which are engineered for high-performance filtering in automotive and industrial applications. The series emphasizes durability and low loss characteristics to support modern electronic systems requiring efficient noise management.
Replacement Considerations
Cross-reference with other AEC-Q200 qualified common mode chokes offering similar 120 µH inductance and 27 A current ratings. Verify pinout compatibility and physical dimensions to ensure mechanical fit within the existing assembly without redesigning the PCB layout.
