The present invention relates to transformer inductor devices and to the methods of construction for inductive components such as inductors, chokes, and transformers. Plural via holes 12 are formed through a ferromagnetic substrate 10 . Primary 32 and secondary 34 conductors are placed through common vias to form a plurality of cell transformers have a 1:1 turns ratio. Circuits connect these primary and secondary winding in parallel and serial combustion to provide a transformer having the desired turns ratio.
