Abstract: Circuit board transformer components (100, 200, 300, 400) include a bobbin (102, 202, 302, 402) having at least one ground pin (152, 252, 352, 452) with a board pin portion (160, 260, 360, 460) and a component ground section (162, 262, 362, 462) extending substantially perpendicular to the board pin portion. The component ground section is secured to a magnetic piece or the bobbin to address electromagnetic interference in a power supply application. The components are manufacturable with a reduce number of steps and greater uniformity with improved performance characteristics.
