Abstract:
1. A multi-winding inductor, comprising: a magnetic core having a first side opposite a second side; a first foil winding passing through the magnetic core from the first side to the second side, a first end of the first foil winding extending from the first side of the core and wrapping under the core to form a first solder tab under the core suitable for surface mount soldering to a printed circuit board, a second end of the first foil winding extending from the second side of the core to form a second solder tab suitable for surface mount soldering to a printed circuit board; and a second foil winding passing through the magnetic core from the first side to the second side, a first end of the second foil winding extending from the second side of the core and wrapping under the core to form a third solder tab under the core suitable for surface mount soldering to a printed circuit board, a second end of the second foil winding extending from the first side of the core to form a fourth solder tab suitable for surface mount soldering to a printed circuit board; a portion of the first solder tab being laterally adjacent to a portion of the third solder tab under the magnetic core.
