7. A choke coil comprising:
a conductor element having a first end and a second end, and made of electrically conducting material, the conductor element comprising a plurality of coil turns between the first end and the second end;
a first terminal member provided at the first end of the conductor element; and
a second terminal member provided at the second end of the conductor element,
wherein the first terminal member is adapted for electrically connecting the choke coil to a first circuit terminal of an electric circuit, and the second terminal member is adapted for electrically connecting the choke coil to a second circuit terminal of the electric circuit, and the choke coil has a longitudinal direction extending between the first terminal member and the second terminal member,
the first terminal member comprises a first aperture extending in a first lateral direction perpendicular to the longitudinal direction, and adapted to receive a first mounting component for electrically connecting the first terminal member to the first circuit terminal of the electric circuit, and
the second terminal member comprises a second aperture extending in a second lateral direction perpendicular to the longitudinal direction, and adapted to receive a second mounting component for electrically connecting the second terminal member to the second circuit terminal of the electric circuit,
wherein the first terminal member is adapted to compensate lateral dimensional variance between locations of the first circuit terminal and second circuit terminal, and the second terminal member is adapted to compensate longitudinal dimensional variance between locations of the first circuit terminal and second circuit terminal, wherein the lateral dimensional variance is perpendicular to the longitudinal direction, and the longitudinal dimensional variance is parallel to the longitudinal direction.
