Procurement Notes

Verify the specific suffix codes against official KEMET documentation to ensure exact electrical tolerances and packaging configurations. Confirm that the AEC-Q200 qualification status meets your project's automotive reliability requirements. Cross-reference the inductance tolerance range (-30% to +50%) with circuit design constraints to ensure proper filter performance under varying conditions.

Selection Notes

Select this component when designing single-phase power filters requiring high current capacity and automotive-grade reliability. The 1.2 mH inductance value is suitable for attenuating high-frequency noise while maintaining low insertion loss due to its minimal DC resistance. Ensure the physical dimensions of the radial through-hole package fit within the available PCB real estate and mounting constraints.

Part Context

This part belongs to the KEMET SCF-XV series of common mode chokes, which are engineered for demanding power electronics applications. The series emphasizes high saturation current and robust construction for automotive and industrial environments. The SCF39XV-310-1R9B007JH specifically addresses single-phase filtering needs with standardized through-hole mounting for ease of assembly.

Replacement Considerations

Check for direct substitutes within the SCF-XV series or equivalent AEC-Q200 qualified common mode chokes from other manufacturers. Ensure replacement parts match the 1.2 mH inductance, 31 A current rating, and 1000 V voltage specifications. Verify physical footprint compatibility for radial through-hole installation.
