Abstract
The technology described in this document can be embodied in an apparatus that includes at least four magnetic cores, wherein each core is for supporting an inductor of a filter circuit. Each of the cores include a first section, and a second section separated from the first section by an adhesive layer. The apparatus also includes an air-core structure to store magnetic energy, the air-core structure including a set of focusing projections that define a hollow cavity. The individual focusing projections of the set are disposed on different sides of the hollow cavity to focus magnetic field from the at least four magnetic cores through the hollow cavity.
