Common Mode Chokes Applications

• SEPIC (Single-Ended Primary Inductor Converter) circuits
• Power supply input stages requiring coupled inductance
• Compact DC-DC conversion modules

Common Mode Chokes Procurement Notes

Verify the specific suffix 'MLC' against the manufacturer's current datasheet to confirm exact electrical tolerances and termination specifications. Ensure the ordering code matches the required inductance value of 82 µH and that the component meets all relevant environmental compliance standards for the target assembly process.

Common Mode Chokes Selection Notes

Select this component when a tight magnetic coupling ratio is required for energy transfer efficiency in non-inverting buck-boost configurations. The shielded design supports high-density PCB layouts. Confirm that the physical dimensions of the 3030 package fit within the available board space constraints.

Common Mode Chokes Part Context

This part belongs to the MSD7342 series of coupled power inductors. The series is characterized by its ability to provide both inductance and coupling in a single compact footprint, making it suitable for modern portable electronics and industrial power systems where space is limited.

Common Mode Chokes Replacement Considerations

Consult official Coilcraft documentation for direct cross-references. Verify that any substitute maintains the 1:1 coupling ratio and compatible saturation current ratings.
