초록

A low-profile transformer or inductor includes a leg of a magnetically permeable core. A tube-type winding arrangement is made by use of a flat, flexible dielectric sheet, on one side of which a broad conductive area is affixed, and on the other side of which a plurality of mutually parallel elongated regions are affixed. The dielectric sheet is rolled into a tube defining a parting line which is perpendicular to the axes of elongation of the conductive strips. The discontinuous elongated strips are formed into a continuous winding by means of stitches. ...
