Procurement Notes
Verify the specific suffix codes against official KEMET documentation to ensure correct inductance tolerance and current ratings. Confirm package type compatibility during integration. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Ensure storage conditions meet manufacturer specifications for ferrite materials.
Selection Notes
Select this component when four-channel common mode filtering is required at high currents. The 50 A rating suits heavy-duty power lines. Verify that the 1000 V rating aligns with system insulation requirements. Consider thermal management due to low DC resistance and high current handling capabilities in enclosed spaces.
Part Context
This part belongs to the SCF-XV series of high permeability ferrite toroidal coils by KEMET. These components are engineered for robust performance in demanding environments. The series offers various inductance values tailored for different filtering needs while maintaining compact physical dimensions suitable for space-constrained designs.
Replacement Considerations
Check for direct substitutes within the SCF39XV-Z family. Verify equivalent inductance and current ratings before substitution. Ensure mechanical footprint compatibility if replacing on existing PCBs.
