Abstract
An inductive component, such as a transformer, is made by applying conductive tracks onto a thin, foldable substrate ( 10 ) and then Z-folding the substrate so that the conductive tracks from a coil. A ferrite core is then placed through the coil. In order to maximise the current capacity of the transformer, there are electrical connections between leaves not only around each fold line ( 14 ) where the track traverses the fold line, but also between specially prepared areas X-X of the tracks which end up facing each other from adjacent folds once the substrate has been folded.
