A filter for an electric machine is disclosed. The filter has an inductor, which is a coil, and a capacitor. The coil has multiple windings, and each turn of the windings includes at least one conductor which is designed to be flat. By virtue of the flat conductor of the coil, the capacitance of the filter is thus formed in the coil itself In the process, the surface of one conductor is arranged opposite the surface of an adjacent conductor.

A bridge combiner can be implemented as a coupling circuit that includes a common node and configured to couple the common node to a first group of filters through a first path and to couple the common node to a second group of one or more filters through a second path. The coupling circuit can include a resonator such that an impedance provided by each filter of the first group for a signal in each band of the second group results in the signal being sufficiently excluded from the first path, and such that an impedance provided by each filter of the second group for a signal in each band of the first group results in the signal being sufficiently excluded from the second path.

An EMI filtering, coaxial power connector may be formed as an inline component or a port of a device. The connector may have dimensions to accept F-type coaxial connectors. The connector includes a conductive outer shell with a first opening and a second opening. A dielectric member is disposed within the shell. A conductive pin is supported by the dielectric member. A feed-through capacitor has a central opening and a first lead formed within the central opening. The pin is electrically connected to the first lead. A second lead of the capacitor is formed at an outer perimeter of the capacitor and is electrically connected to the shell. A metal plate is mounted within the shell. The plate is disk-shaped with a central hole. An outer perimeter of the plate is in electrical contact with the shell. The pin passes through the central hole without making electrical contact with the plate, and the plate resides between the second opening of the shell and the capacitor.

A safety device for an automotive EMI filter that is connected in series with a filtering capacitor. The safety device has normally a low impedance and does not alter the functioning of the filter, but it is configured to present an increased inductance in the event of a discharge. The device reduces the discharge current that can be accidentally conducted through a human body.
