MSD7342-223MLC

Common Mode Chokes Overview

The MSD7342-223MLC is a shielded coupled power inductor from Coilcraft, designed for surface-mount applications. It features a 1:1 coupling ratio and utilizes a ferrite core with magnetic shielding to minimize electromagnetic interference. The component is RoHS compliant and suitable for compact circuit designs requiring tight winding-to-winding coupling.

Common Mode Chokes Feature Summary

• Magnetic shielding provides compact packaging and reduced external field interference
• 1:1 coupling ratio ensures tight winding-to-winding interaction
• Dual-wound structure supports SEPIC converter topologies

Common Mode Chokes Applications

• SEPIC power converter circuits
• Compact DC-DC conversion modules
• Electromagnetically sensitive power supply designs

Common Mode Chokes Procurement Notes

Verify the specific suffix (e.g., MLC) against official Coilcraft documentation to confirm tolerance and termination specifications. Ensure compatibility with automated pick-and-place equipment due to the surface-mount package geometry. Cross-reference part numbers carefully as suffixes may indicate variations in lead finish or tolerance that affect soldering profiles.

Common Mode Chokes Selection Notes

Select this component when a 1:1 coupled inductor is required for SEPIC applications within space-constrained environments. The magnetic shielding makes it suitable for high-density layouts where crosstalk must be minimized. Verify thermal requirements and saturation current limits against the specific load conditions of the target power stage.

Common Mode Chokes Part Context

This part belongs to the MSD7342 series of shielded coupled power inductors manufactured by Coilcraft. The series is characterized by its dual-wound construction and ferrite core technology, offering consistent performance for power conversion applications requiring isolated yet coupled energy storage elements.

Common Mode Chokes Replacement Considerations

Consult official Coilcraft substitution guides for verified equivalents. Generic coupled inductors may lack the specific 1:1 coupling factor or magnetic shielding characteristics required for stable SEPIC operation.
