DC-DC conversion stages

Common Mode Chokes Procurement Notes

Verify the specific suffix (e.g., MLC) against the manufacturer's official datasheet to confirm exact electrical parameters and packaging specifications. Ensure the procurement channel sources genuine components to maintain AEC-Q200 compliance and performance integrity. Cross-reference part numbers carefully as suffixes may indicate variations in tape-and-reel quantities or terminal finishes.

Common Mode Chokes Selection Notes

Select this component when designing SEPIC converters requiring high coupling efficiency and magnetic shielding in a small footprint. The 1.35 A current rating and low DC resistance make it suitable for moderate-power automotive applications. Verify that the 18 µH value aligns with the specific circuit design requirements for voltage conversion ratios and ripple current handling.

Common Mode Chokes Part Context

This component belongs to the MSD7342 series of 1:1 coupled power inductors manufactured by Coilcraft. The series is characterized by its shielded construction and suitability for space-constrained designs. These inductors are engineered to provide stable performance in power conversion topologies where tight magnetic coupling between windings is critical for efficiency.

Common Mode Chokes Replacement Considerations

Consult the official MSD7342 series datasheet for verified substitute part numbers with compatible inductance and current ratings. Ensure any replacement maintains the same physical footprint and AEC-Q200 qualification if automotive use is required. Do not assume interchangeability without verifying electrical parameters against the original specification.
