Abstract
A three or four terminal noise filter and a method of making the same is disclosed. A pair of conductive bands are wound in a spiral manner with a thin insulating separator therebetween. The first conductive band is made of either electrically or electromagnetically conductive foil to form an inductance between terminals coupled to both ends of such foil. The first conductive band also provides capacitance distributed over its entire length between itself and the second conductive band. The second conductive band is made of electromagnetically conductive foil, such as an iron foil. The noise filter can be made by rolling the sandwich of conductive bands and insulators longitudinally.
