1. A motor vehicle comprising:
a direct current (DC) voltage onboard power supply;
at least one component connected to the DC voltage onboard power supply,
wherein the at least one component, in operation, energizes the DC voltage onboard power supply in at least one operating mode of the motor vehicle, or the DC voltage onboard power supply, in operation, energizes the at least one component in at least one further operating mode of the motor vehicle;
a filter module,
wherein the at least one component is connected across the filter module to the DC voltage onboard power supply,
wherein the filter module is connected across at least one onboard power supply connection of the filter module to the DC voltage onboard power supply and across at least one component connection of the filter module to the at least one component,
wherein the filter module, in operation, dampens an alternating voltage coupled into the at least one component connection by the at least one component; and
a shield that encloses either at least one power supply line that connects the at least one component to the at least one component connection of the filter module, or at least one connection region in which the at least one component connection contacts the at least one onboard power supply connection of the at least one component together with the at least one component and the filter module,
wherein the shield, in operation, at least partly shields out electromagnetic radiation emitted from the at least one power supply line or the at least one component connection by virtue of the alternating voltage coupled into the at least one component connection, and
wherein the at least one component connection is reversibly detachable from the at least one component or the at least one power supply line of the DC onboard power supply.
