An integrated vertical inductor includes a bobbin having an elongated, hollow tube, an upper flange disposed at an upper end of the elongated, hollow tube, and a base structure integrated with a lower end of the elongated, hollow tube. The elongated, hollow tube comprises a central opening extending along its longitudinal direction. The base structure comprises a lateral opening communicating with the central opening. A first magnetic core piece is installed in the central opening of the elongated, hollow tube. A second magnetic core piece is juxtaposed with the first magnetic core piece. A plurality of electrodes is disposed on a bottom surface of the base structure.
