Procurement Notes

Verify the complete part number including suffixes such as 'JH' or 'JV', as these may indicate specific packaging or tolerance variations. Confirm that the required voltage and current ratings align with the system design before procurement. Ensure compliance with AEC-Q200 requirements if the application mandates automotive-grade components. Cross-reference datasheets from authorized distributors to confirm availability and exact specifications.

Selection Notes

Select this component when high current handling capability near 19 A is required alongside significant common mode noise attenuation. The 1.6 mH inductance offers substantial impedance at switching frequencies. Consider the radial through-hole package for robust mechanical mounting in industrial enclosures. Verify that the 1000 V rating exceeds the peak transient voltages present in the target circuit to ensure long-term reliability.

Part Context

This component belongs to the KEMET SCF-XV series of common mode chokes. These coils are engineered for wide variety of high-power applications requiring reliable EMI suppression. The series typically utilizes materials suitable for demanding thermal environments. The SCF29XV model specifically targets scenarios where both high current capacity and high voltage isolation are critical design constraints.

Replacement Considerations

Check for equivalent parts within the SCF-XV family that match the 1.6 mH inductance and 19 A current rating. Verify that any substitute maintains the same 1000 V rating and AEC-Q200 qualification if automotive use is intended. Ensure physical dimensions and lead spacing are compatible with existing PCB layouts.
