Transformer or inductor containing a magnetic core having abbreviated sidewalls and an asymmetric center core portion |
摘要 |
An inductor or transformer for mounting on a PCB has a two-part magnetic core structure and at least one coil wound on a bobbin. Each core part has a backwall and an abbreviated outer skirt extending from the backwall and an asymmetric center core element extending from the backwall in the same direction as the outer skirt along a longitudinal axis parallel with the mounting plane and including the centroid of the center core element. The center core element is asymmetric relative to a dividing plane parallel with the mounting plane and including the longitudinal axis, such that a greater portion of the center core element lies on a side of the dividing plane than on an opposite side of the dividing plane. In one preferred form, the center core element has a cross-sectional shape resembling a "D" character turned on its side, or "lazy D" shape.
