Procurement Notes
Verify the specific datasheet version to confirm exact inductance tolerances and thermal ratings. Ensure the selected variant matches the required operating current and voltage specifications for the target circuit. Cross-reference the manufacturer's official documentation to validate compliance with relevant safety standards before integration into final designs.
Selection Notes
Select this component when normal mode noise attenuation is required at the AC input stage. Consider the 3 A current rating and 42 mΩ resistance to ensure compatibility with the system's power budget. Evaluate the physical dimensions of the radial leaded package against available PCB real estate constraints.
Part Context
This component belongs to KEMET's SN series of AC line filters, which are engineered for general-purpose EMI suppression. The series offers various inductance values to suit different frequency ranges and current requirements, providing a standardized solution for meeting regulatory emissions limits in electronic devices.
Replacement Considerations
Consult KEMET's official substitution guide or equivalent distributor databases for verified cross-references. Ensure any alternative part matches the 72 µH inductance, 3 A current rating, and 42 mΩ resistance parameters to maintain circuit performance.
