Procurement Notes
Verify the specific part number against official KEMET documentation to confirm electrical ratings and package details. Ensure compliance with project-specific requirements such as AEC-Q200 certification and thermal performance limits before finalizing procurement decisions.
Selection Notes
Select this component when designing circuits requiring robust common mode noise attenuation for single-phase systems. Consider the 14 A current rating and low DC resistance for efficient power transmission. Verify that the 1000 V insulation rating meets the system's voltage isolation requirements.
Part Context
This component belongs to the KEMET SCF39XV series of through-hole common mode chokes. These components are engineered for high-performance electromagnetic interference (EMI) filtering in demanding electronic environments, particularly where automotive reliability standards apply.
Replacement Considerations
Consult official KEMET substitution guides for verified alternatives. Do not assume compatibility based on similar inductance values alone; verify current ratings, physical dimensions, and impedance characteristics.
