Common Mode Chokes Procurement Notes

Verify the specific suffix against the manufacturer's official datasheet to confirm electrical characteristics and compliance status. Ensure the ordering code matches the required inductance value and tolerance. Confirm availability through authorized distributors as stock levels fluctuate. Check for any recent updates to the component specifications on the manufacturer's website before finalizing procurement.

Common Mode Chokes Selection Notes

Select this component when a shielded, coupled inductor is required for SEPIC or similar topologies. Consider the 0.32 A current rating and 3.05 ohm DC resistance during circuit design. Verify that the 390 µH inductance meets the system's ripple and regulation requirements. Ensure the surface-mount footprint fits the PCB layout constraints.

Common Mode Chokes Part Context

This part belongs to the MSD7342 series of shielded coupled power inductors by Coilcraft. The series offers various inductance values and current ratings while maintaining a consistent footprint and magnetic shielding characteristics. It is distinct from single-wound power inductors like the MSS7341 series due to its dual-winding configuration.

Common Mode Chokes Replacement Considerations

Consult the Coilcraft MSD7342 series datasheet for alternative inductance values within the same package. Verify compatibility with existing PCB footprints and thermal management requirements when considering substitutes.
