Procurement Notes
Verify the specific datasheet version when ordering, as manufacturer documentation may be hosted by distributors. Confirm that the part identification matches the official KEMET designation SS21V-180029. Ensure the procurement source provides the original technical document rather than third-party summaries to guarantee accurate electrical specifications and handling instructions.
Selection Notes
Select this component for circuits requiring common mode filtering at currents up to 1.8 A. The 2.9 mH inductance value is critical for the intended noise attenuation profile. Ensure the operating environment stays within the -25°C to +120°C range. Verify that the PCB layout accommodates the through-hole package dimensions and spacing requirements specified in the official mechanical drawings.
Part Context
This component is part of the KEMET SS21V series of common mode chokes. The series offers various sizes and specifications utilizing specialized ferrite materials. These components are engineered for power applications where high-frequency noise reduction is necessary, providing a robust solution for electromagnetic interference mitigation in electronic systems.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult the official KEMET catalog for alternative values within the SS21V series if exact specifications cannot be met.
