Abstract
A magnetic component having a magnetic core structure includes a core body with a notched region for reducing non-essential core material. The notched region has the cross-sectional shape of a trapezoid and includes two notch walls separated by a middle wall. The notch walls are each oriented at an obtuse angle relative to the middle notch wall. The core structure reduces the cost of manufacture and the size of the magnetic component by eliminating non-essential core material from regions of the core that have little or no impact on the magnetic performance of the component. The desired magnetic flux path in the component remains substantially unaffected by the removal of the non-essential core material. The body of the core may also include one or more angled shoulders positioned at the corners of the core body to further eliminate non-essential core material.
