摘要： The invention relates to a transformer (10, 10') with a core (11) which has a center piece (11a) with a first and a second flange (11b, 11c), in which a first and a second winding (12, 13) of the transformer (10, 10') are wound on the center piece (11a). To produce a transformer as compact as possible which allows simple adaptation to limit leakage currents, it is proposed that the winding end pieces (12a, 12b) of the first winding (12) guided out of the winding body are guided through at least one recess in the first flange (11b) and that winding end pieces (15a, 15b) of the second winding (13) guided out of the winding body are provided which form at least partly loose line ends. Alternatively, the winding end pieces (12a, 12b) of the first winding (12) guided out of the winding body are guided immediately about the edge of the first flange (11b) and connected with connecting elements (14a, 14b) which are arranged on the side of the first flange (11b) opposite the center piece (11a).
