Abstract: The device comprises a first winding which is provided on a core (1) and which is composed of electrically conductive segments (27) which are shaped approximately as a U-shaped plate having two substantially parallel end portions (33, 35) of unequal width and a wedge-shaped central portion (37). The segments (27) are formed as metallized portions of the outer surface of a cap (19) which is made of an electrically insulating material and which is shaped as a ring having a U-shaped cross-section. The segments are electrically isolated from one another by non-metallized strip-shaped portions (25) of the outer surface of the cap (19). The cap (19) comprises metallized pins (21) which constitute connection members for the segments and which are connected to electrical conductors (39), for example on a printed circuit board (41). In conjunction with the segments (27), the conductors (39) constitute the first winding.
