Common Mode Chokes Procurement Notes

Verify the specific suffix 'C' against the manufacturer's current datasheet to confirm exact electrical tolerances and packaging specifications. Ensure the procurement channel provides original documentation from Sumida Corporation or authorized distributors to validate authenticity and compliance with environmental standards.

Common Mode Chokes Selection Notes

Select this component when designing circuits requiring common mode noise attenuation on data or signal lines. Consider the 470 µH inductance value and 0.2 Ω DCR limits relative to the target current requirements. Verify that the 9.5 x 5.65 mm footprint fits within the available PCB area constraints.

Common Mode Chokes Part Context

This part belongs to the CPFC54 series of DC common mode chokes. The series offers various inductance values tailored for different filtering needs while maintaining a consistent small surface-mount package profile suitable for space-constrained electronic designs.

Common Mode Chokes Replacement Considerations

Consult Sumida's official cross-reference lists for verified substitutes. Ensure any alternative maintains equivalent inductance, DCR, and physical dimensions to preserve circuit performance and board compatibility.
