    Abstract: A microelectronic device (100) includes a magnetic component (110) having a first magnetic core segment (108) and a second magnetic core segment (154), with a winding lamina (128) between them. The first magnetic core segment (108) includes a winding support portion (112) with ferromagnetic material. The winding lamina (128) is attached to the winding support portion (112). The first magnetic core segment (108) also includes an extension portion (114) with ferromagnetic material extending from the winding support portion (112). The winding lamina (128) has winding loops (134) of electrically conductive material that surround ferromagnetic material. A filler material (144) is formed between the winding lamina (128) and the first magnetic core segment (108), contacting both the winding lamina (128) and the first magnetic core segment (108). The second magnetic core segment (154) is attached to the extension portion (114) of the first magnetic core segment (108). The second magnetic core segment (154) includes ferromagnetic material. The winding loops (134) are electrically coupled to external leads (106) through electrical connections.
