摘要： A choke coil comprising a conductor element (2) having a plurality of coil turns, a first terminal member (41) adapted for electrically connecting the choke coil to a first circuit terminal (61) of an electric circuit, and a second terminal member (42) adapted for electrically connecting the choke coil to a second circuit terminal (62) of the electric circuit. The first terminal member (41) is adapted to compensate lateral dimensional variance between locations of the first circuit terminal (61) and second circuit terminal (62), and the second terminal member (42) is adapted to compensate longitudinal dimensional variance between locations of the first circuit terminal (61) and second circuit terminal (62), wherein the lateral dimensional variance is perpendicular to a longitudinal direction of the choke coil extending between the first terminal member (41) and the second terminal member (42), and the longitudinal dimensional variance is parallel to the longitudinal direction.

摘要： A capacitor assembly comprising at least one capacitor (2) each having a first end (21) and a second end (22) spaced apart in a longitudinal direction, and a first terminal (41) and a second terminal (42) located at the first end (21) of the capacitor (2), the first end (21) being provided with a first surface (211), and the second end (22) being provided with a second surface (222); a heat sink (6) having a first cooling surface (61); and a connection system connecting the at least one capacitor (2) heat conductively to the heat sink (6) such that the second surface (222) of each of the at least one capacitor (2) is in heat conductive connection with the first cooling surface (61). The connection system is in contact with the first surface (211) of each of the at least one capacitor (2).
