Procurement Notes

Verify the specific part number suffix to ensure compatibility with required lead configurations and packaging types. Confirm that the thermal ratings align with the operational environment of the target application. Cross-reference official manufacturer documentation to validate electrical parameters before integration into design specifications.

Selection Notes

Select this component when designing circuits requiring common mode noise attenuation at low frequencies. Ensure the operating current does not exceed 100mA to prevent saturation or excessive heating. Verify that the physical dimensions fit the available board space and that the through-hole pitch matches the PCB layout requirements.

Part Context

This component belongs to the KEMET SU-9VF series of common mode chokes. These components are engineered for general-purpose EMI filtering applications. The series offers standardized form factors suitable for automated assembly processes while maintaining consistent electrical performance across the product line.

Replacement Considerations

Consult official substitution guides for compatible alternatives. Verify that any replacement part matches the 25 mH inductance, 250V rating, and 100mA current capacity. Ensure mechanical footprint compatibility to avoid PCB redesign.
