Procurement Notes
Verify the specific part number SU9V-R03090 against official KEMET documentation to ensure compatibility with circuit requirements. Confirm that the 300 mA current rating and 9 mH inductance meet the design specifications. Check the operating temperature range and package type for physical integration. Ensure the source is authorized to guarantee component authenticity and traceability.
Selection Notes
Select this component when common mode noise suppression is required for AC lines or data signals. Consider the 300 mA current limit and 9 mH inductance value for circuit matching. Evaluate the proprietary ferrite material properties for effectiveness in the target frequency range. Ensure the through-hole package fits the PCB layout constraints.
Part Context
The SU9V series from KEMET includes various common mode chokes with different inductance and current ratings. This specific model belongs to the SU9V/9H type family, characterized by its use of proprietary ferrite materials. It is part of a broader range of filters designed for noise countermeasures in industrial and consumer electronics.
Replacement Considerations
Check KEMET's official substitution list for equivalent parts with similar inductance and current ratings. Verify compatibility with existing PCB footprints and thermal requirements before replacing.
