Multi-turn inductors
First Claim
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.

Abstract
A multi-winding inductor includes a first foil winding and a second foil winding. One end of the first foil winding extends from a first side of the core and wraps under the core to form a solder tab under the core. One end of the second foil winding extends from a second side of the core and wraps under the core to form another solder tab under the core. Respective portions of each solder tab are laterally adjacent under the magnetic core. A coupled inductor includes a magnetic core including a first and a second end magnetic element and a plurality of connecting magnetic elements disposed between and connecting the first and second end magnetic elements. A respective first and second single turn foil winding is wound at least partially around each connecting magnetic element. Each foil winding has two ends forming respective solder tabs.
