摘要： The invention relates to a film capacitor for power electronics, which comprises a first electrically conductive layer, which is arranged on a first end side face of the film capacitor, wherein the surface normal of the first electrically conductive layer is perpendicular to the surface normals of dielectric films of the film capacitor. A second electrically conductive layer is arranged on a second end side face opposite from the first end side face, wherein the surface normal of the second electrically conductive layer is perpendicular to the surface normals of the dielectric films of the film capacitor. The film capacitor has at least one inner passage, which extends from the first electrically conductive layer to the second electrically conductive layer, wherein the passage is formed by removal of capacitor material. The invention also relates to a capacitor assembly.
