<p>At least a first and at least a second metal layer (20, 21) are wound in the longitudinal direction for a certain number of windings, said metal layers being partially superimposed and electrically insulated from one another. For each winding, at least one of the metal layers is formed with at least two transverse interstices (27, 28) at positions resulting in their being radially aligned in the finished coil, so as to divide said coil into at least two separate capacities (29, 30). The Intestices (27, 28) are preferably formed by evaporation of the metal.</p> |
