An inductive electronic module, comprising a core element having an inner limb (12; 29a) and at least two lateral limbs (14, 16; 33a, 35a; 37a, 39a) associated the inner limb on both sides, the core element being provided with windings (N1, N2, N3, N4) for forming a transformer. A first winding (N1, N2: 47, 49; 51, 53) is implemented as a series connection composed of two partial windings. A first partial winding is formed on a first lateral limb, and a second partial winding is formed on a second lateral limb.
