A magnetic component apparatus includes a bobbin having a bobbin body, a first pin rail, a second pin rail, and a longitudinal axis. First and second pin rows are located on the first pin rail. The second pin row is located at an exterior position from the first pin row. A third pin row is located on the second pin rail. The first, second, and third pin rows can be oriented in a direction transverse to the longitudinal axis. A plurality of windings can be located on the bobbin body. Some embodiments can include a fourth pin row located on the second pin rail, the fourth pin row located at an exterior position from the third pin row. In some embodiments one or more wire guide channels can be defined in the first or second pin rails to help keep breakout wires from the plurality of windings separate.
