Claim Text:
1. A planar transmitter having: a layer structure having a plurality of circuits, wherein a first circuit and at least a second circuit are galvanically separated from one another by means of at least one first insulation layer, a magnetic core of a non-closed structure, in which a first magnetic layer and a second magnetic layer are separated from one another and are assigned to different potential groups, wherein the first magnetic layer delimits a first side of the layer structure, and the second magnetic layer delimits a second side of the layer structure, wherein the first circuit borders on the first magnetic layer, and the second circuit borders on the second magnetic layer, wherein at least two conductive layers form one or more windings of a coil, in that the conductive layers are connected with an electrical connection, wherein the first circuit and the second circuit have a minimum insulation distance T wherein the minimum insulation distance makes at least one of galvanic separation between the first circuit and the second circuit and, intrinsically safe galvanic separation, available, wherein the distance between the first circuit and the second circuit does not go below the minimum insulation distance T wherein a total insulation thickness between the first magnetic layer and the second magnetic layer amounts to (N−1)×T wherein, at a required minimum insulation distance T
