1. An EMC filter (1) for a control device (15),
wherein the filter (1) includes a multilayer circuit carrier (1) comprising electrically conductive layers (20, 21, 23, 24, 26, 28, 29, 31, 32, 35, 37) and electrically insulating layers (2, 3, 4, 5, 6, 7),
wherein
the circuit carrier (1) forms at least two filter capacitors (8, 9, 10), wherein the filter capacitors (8, 9, 10) are respectively formed by at least two electrically conductive layers (20, 23, 26, 29, 32, 35) that are formed in the circuit carrier (1) and lie across from one another and/or extend parallel at a distance from each other.
