Common Mode Chokes Procurement Notes

Verify the specific voltage rating and current capacity against your circuit requirements before integration. Confirm that the through-hole footprint matches your PCB layout. Ensure the operating temperature range meets your environmental conditions. Check for RoHS compliance if required by your manufacturing standards. Validate the inductance value at the intended test frequency.

Common Mode Chokes Selection Notes

Select this component when a 2 mH inductance is required for common mode noise attenuation in 250 VAC systems. The 5 A current rating suits moderate power applications. Consider the physical dimensions and through-hole mounting style during mechanical design. Compare thermal performance and DCR against alternative chokes in the same series for optimal efficiency.

Common Mode Chokes Part Context

This component belongs to the KEMET SC series of common mode chokes. These components are engineered for general-purpose EMI filtering in AC power applications. The series offers various inductance values and current ratings to suit different power levels and noise profiles.

Common Mode Chokes Replacement Considerations

Substitutes must match the 2 mH inductance, 5 A current rating, and 250 VAC voltage rating. Verify compatible through-hole pin spacing and core material properties. Ensure the replacement part meets the same temperature and safety certifications.
