PURPOSE: A coil for automated mounting is provided to minimize stray losses through the air gap between the turns of the coil, while achieving a simple and fully automatic mounting on a printed circuit board. CONSTITUTION: An air coil having a plurality of turns, is characterized in that the turns include a magnetic material. The coil is an air coil for high frequency uses and the turns of the air coil are clad with a material having good high frequency properties, particularly copper, gold or silver. Alternatively, an air coil having a plurality of turns, is characterized in that the turns have an outer layer(3) for carrying an electric current and a magnetic material in the interior of turns.
