Abstract
In an embodiment a coil includes a tube comprising a tube wall composed of an electrically conductive material, wherein the tube wall has an inductive portion in which a gap is arranged that shapes the tube wall so the tube wall forms a helix in the inductive portion, and wherein the tube wall has two contact portions, each contact portion forming an electrical terminal.
Claims27
A coil comprising:
- an inductive portion in which a helix is formed by a gap in a tube wall of a tube, the tube wall being composed of an electrically conductive material;
- two contact portions forming electrical terminals, each contact portion being formed from the tube wall;
- and
- two connecting portions formed from the tube wall, each connecting portion connecting one of the two contact portions to the inductive portion,
- wherein each of the contact portions has two arms pointing oppositely along a direction perpendicular to a longitudinal axis of the helix,
- wherein the arms are planar in a plane parallel to the longitudinal axis of the helix, and
- wherein each connecting portion is shorter in the direction perpendicular to the longitudinal axis of the helix than the respective arms along an entire length in the direction perpendicular to the longitudinal axis of the helix, allowing positioning the coil on a printed circuit board along the entire lengths of the arms.
