Common Mode Chokes Procurement Notes

Verify the specific manufacturer part number against official KEMET documentation to ensure authenticity. Confirm that the component meets required safety certifications for your target market. Check datasheet specifications for thermal derating curves if operating near maximum current limits. Ensure PCB layout accommodates the specified through-hole footprint and mechanical dimensions.

Common Mode Chokes Selection Notes

Select this component when designing circuits requiring common mode noise attenuation on AC lines. The 2.8 mH inductance offers effective filtering for standard power frequencies. Consider the 3 A current rating to ensure adequate headroom for peak loads. Verify that the through-hole mounting style aligns with the assembly process and board design constraints.

Common Mode Chokes Part Context

This component belongs to the KEMET SC-J series of common mode chokes. These filters are engineered for robust performance in power line applications. The series provides standardized solutions for EMI suppression. The SC-03-28J variant specifically targets higher current requirements compared to lower-rated counterparts in the same family.

Common Mode Chokes Replacement Considerations

Check KEMET's official substitution guide for equivalent parts within the SC-J series. Verify compatibility of inductance, current rating, and physical dimensions before replacing.
