Abstract (en)
[origin: EP2521146A2] The electrical choke coil (1) has spiral coil turns (10,12) that produce an inductance. The coil turn is formed from rectangular wire and is wound around a cavity with an angular cross-section. A flattened extension portion of the rectangular wire is extended toward a coil longitudinal axis (60). The windings of the coil turn are extended in a plane. The winding circulation of the rectangular wire is connected with winding circulation of the coil turn and is radially spaced wound along the coil longitudinal axis.
