Shown on this slide are three Eaton Coiltronics dual winding coupled inductor product families for use in SEPIC converters. The DRQ and SDQ families use ferrite shielded drum cores with bifilar windings. These shielded drum families include three different sized footprints:  5, 7.3 and 12.3 mm, in a square pattern. Heights range from 1.2 mm up to 8 mm and cover a broad range of power and currents. The Econo-Pac, Octa-Pac and Octa-Pac Plus families use toroidal cores and distributed-gap powdered core materials. Three different core materials allow users to select parts based on cost or performance, whichever parameter is most critical in their design. This family offers two different sized footprint options:  8.89 mm or 11.43 mm square pattern. Four heights are available, ranging from 4.19 mm up to 6.35 mm. All three cores are offered in all size options, giving designers a wide range of product choices.
