Abstract
A printed circuit board assembly includes a printed circuit board and a ferrite. The printed circuit board has a substantially planar top surface and a substantially planar bottom surface. The ferrite has an annular cross section that defines a channel. The ferrite is positioned on the printed circuit board such that a portion of the plurality of traces passes through the channel.
Claims19
A printed circuit board assembly, comprising:
- a printed circuit board, comprising:
- a plurality of traces;
- two slots defining a tongue portion of the printed circuit board;
- a substantially planar top surface;
- and
- a substantially planar bottom surface;
- and
- a ferrite having an annular cross section defining a channel,
- wherein the ferrite extends through the two slots and is positioned on and surrounds at least part of the tongue portion of the printed circuit board, such that a portion of the plurality of traces passes through the channel of the ferrite.
