Abstract
An inductive component for a DC/DC converter is made by transferring a copper track (2) from a copper substrate (1) to a first ferrite plate (3). A second ferrite plate (5) is attached by glue to the first ferrite plate so that the track (2) forms an inductor coil sandwiched between the two ferrite plates (3,5). One of the plates has holes (4) in registration with the terminals of the coil, and these holes are filled with solder (5) to provide externally accessible contacts.
