MSD1038V-223MEC

Arrays, Signal Transformers Overview

The Coilcraft MSD1038V-223MEC is a surface-mount, shielded coupled power inductor from the MSD1038V series. It features a 1:1 turns ratio with an inductance of 22 µH per winding, measured at 100 kHz and 0.1 Vrms. The component provides high isolation, rated at 2500 Vrms for one minute between windings. It utilizes a composite core material within a compact molded package designed for low-profile applications.

Arrays, Signal Transformers Feature Summary

• High electrical isolation between windings suitable for isolated topologies
• Shielded magnetic structure to minimize electromagnetic interference
• Composite core construction for stable performance characteristics

Arrays, Signal Transformers Applications

• No-opto isolated flyback converters
• SEPIC converter circuits
• Ćuk converter designs
• Zeta converter architectures

Arrays, Signal Transformers Procurement Notes

Verify the specific termination code and packaging configuration during ordering, as these are distinct from the base part number. Confirm that the required isolation voltage rating aligns with the system safety requirements. Ensure the operating frequency matches the 100 kHz test conditions specified for the inductance value.

Arrays, Signal Transformers Selection Notes

Select this component when high isolation is required in a compact form factor. The 1:1 coupling ratio makes it suitable for specific isolated DC-DC conversion topologies. Consider the physical dimensions and thermal characteristics relative to the PCB layout constraints.

Arrays, Signal Transformers Part Context

This component belongs to the MSD1038V series of miniature high-isolation coupled inductors manufactured by Coilcraft. The series is characterized by its ability to provide significant voltage isolation in a small footprint, addressing space constraints in modern power electronics while maintaining safety standards.

Arrays, Signal Transformers Replacement Considerations

Direct replacements must match the 1:1 turns ratio, 22 µH inductance, and 2500 Vrms isolation rating. Verify that alternative components support the same application topologies such as flyback or SEPIC configurations.
