An arrangement comprising a power semiconductor module, a capacitor, a DC-voltage busbar and a connection device. The module has two flat DC-voltage connection conductors each having a contact section. The DC-voltage connection conductors are arranged closely adjacent to one another on and close to the respective contact sections in the normal direction. The capacitor has two flat capacitor connection conductors each having a contact section. The DC-voltage busbar has two partial busbars each having a contact section.
