Abstract

The coil or transformer consists of a reed-like coil body (1) carrying a winding, and having winding chamber walls (3) at its end, and respectively two E-shaped cores (10a, 10b) of a first size put on the coil body. The middle legs (11) of the cores immerse in the reed aperture (2), and both outer legs (12a, 12b) lie with their insides, at least partially on the winding chamber walls. The walls comprise extrusions (4) for supporting the outside legs of E-shaped cores of a second size, whose leg distance is smaller than that of the cores of the first size.
