Common Mode Chokes Procurement Notes

Verify the specific suffix (MLC) matches the required tolerance and termination specifications. Confirm AEC-Q200 qualification status if the application mandates automotive-grade components. Ensure the 4.7 µH inductance value aligns with the circuit design requirements before procurement.

Common Mode Chokes Selection Notes

Select this component when a shielded coupled inductor is required for SEPIC applications. Consider the 2.46 A current rating and 51 mΩ DC resistance for efficiency calculations. Verify that the 3030 package dimensions fit the available PCB space and that the operating temperature range meets environmental constraints.

Common Mode Chokes Part Context

This part belongs to the MSD7342 series of coupled inductors from Coilcraft. The series offers various inductance values tailored for different power conversion needs. The MSD7342-472MLC specifically provides 4.7 µH inductance with automotive qualification, distinguishing it from non-qualified variants in the same physical footprint.

Common Mode Chokes Replacement Considerations

Check for other MSD7342 series variants with matching 4.7 µH inductance and AEC-Q200 qualification. Ensure any substitute maintains the same 3030 package dimensions and termination finish to guarantee mechanical compatibility.
