Abstract: This invention concerns a smoothing choke of a highly reduced weight. The smoothing choke consists of a magnetic core made up of a stock of trapezoidal metal sheets having the two parallel sides thereof alternately reversed so as to obtain a core of general parallepipedal shape having, at each end thereof, a groove in the shape of a triangular prism. A coil is wound around the core and has outer turns the perimeter of which is successively reduced by step-like winding, from the turns around the central part of the core, symmetrically, to the turns around the ends of the latter.
