Abstract
A magnetic component includes a first core half having a core body with first and second core legs protruding from the core body and a middle core leg protruding from the core body between the first and second core legs. A first U-shaped channel is defined between the first core leg and the middle core leg, and a second U-shaped channel is defined between the second core leg and the middle core leg. A first rounded outer core surface is disposed on the core body oriented substantially parallel to the first U-shaped channel, and a second rounded outer core surface is disposed on the core body oriented substantially parallel to the second U-shaped channel. In some embodiments, a second core half having a similar shape is positioned oppositely adjacent the first core, and a bobbin structure is positioned on the middle core legs such that the first and second U-shaped channels form transverse clearance openings in the magnetic component. Air can be passed transversely through the first and second U-shaped channels to extract heat from the magnetic component.
