Common Mode Chokes Procurement Notes

Verify the specific suffix E2000 against official KEMET documentation to confirm exact electrical tolerances and physical dimensions. Ensure compatibility with existing PCB footprint requirements and thermal management strategies before finalizing procurement decisions.

Common Mode Chokes Selection Notes

Select this component when high inductance values are required for significant noise reduction at lower frequencies. The 4 A current rating makes it suitable for main power lines rather than low-power signal paths. Consider the through-hole mounting style if automated surface-mount assembly is not available or if mechanical stability is prioritized.

Common Mode Chokes Part Context

This component belongs to the KEMET SC series of common mode chokes, which are engineered for general-purpose EMI filtering. The series offers various inductance and current ratings to accommodate different power levels. The SC-04-E2000 specifically targets applications needing substantial impedance to common mode disturbances while maintaining low insertion loss for the desired differential signals.

Common Mode Chokes Replacement Considerations

Consult KEMET's official cross-reference guides for verified substitutes. Ensure any replacement matches the 20.3 mH inductance, 4 A current rating, and 0.15 Ohm DCR specifications to maintain circuit performance.
