Multilayer Common Mode Filter Linear Conductor Design

The conductors are designed with a linear shape that partially overlaps with the coils, creating localized floating capacity at specific positions rather than uniform coverage. This local quality approach maintains attenuation peak depth while avoiding excessive inductance reduction that would occur with solid or annular conductor shapes.

Instead of using solid or annular conductors that completely cover the coil areas, the patent inverts the approach by using linear conductors that deliberately leave gaps. This inversion strategy achieves the opposite effect - maintaining both attenuation performance and impedance levels by avoiding complete overlap between conductors and coils.

The linear conductor configuration creates localized interaction zones where floating capacity is generated, rather than uniform coverage. This allows the patent to achieve sufficient attenuation peak depth while maintaining magnetic flux paths in the non-overlapping regions, thereby preserving inductance.

The conductors are designed to partially overlap with the coils rather than completely covering them. This partial action approach provides just enough floating capacity to maintain attenuation performance while leaving sufficient non-overlapping regions to preserve magnetic flux and inductance.

The linear conductor arrangement creates localized floating capacity that shifts the attenuation peak to high frequencies while maintaining a broader frequency response. The localized nature of the overlap regions allows for controlled impedance characteristics across a wider frequency band compared to solid or annular conductor configurations.

By inverting from complete coverage to partial linear overlap, the patent achieves high-frequency attenuation peak shifting through floating capacity while simultaneously maintaining wider frequency band adaptability. The gaps in the conductor arrangement prevent excessive impedance reduction that would limit the usable frequency range.
