With such known planar coils can be achieved cost-effective only a relatively low inductance, wherein the planar coils also occupy a relatively large amount of space on the substrate surface.
- DE 10 2012 216101 discloses a method for producing a coil integrated in a substrate or applied to a substrate, winding sections of the coil passing through the core material of the coil.
- the document US 2009/0237899 A1 discloses a magnetic component which is arranged in a printed circuit board.

- the magnetic see conductor elements each have at least one bridge-shaped region which connects the first and second ends of the respective magnetic conductor element together, whereby the magnetic circuit is closed.
- the bridge-shaped regions of the magnetic conductor elements may each extend parallel to the plane of the planar coil between its center and its periphery, so that the turns of the planar coil between the first and second ends and the opposite bridge-shaped regions of the two oppositely arranged conductor elements extend therethrough.

Further, the height of the electronic component due to the planar coil can be low, so that results in an arrangement of the electronic component, for example on a circuit board, even at high accelerations only a slight overturning moment. Embodiments of the electronic component are therefore particularly suitable for means of transport, such as automobiles, aircraft and ships, in which high mechanical stresses can occur and / or for applications in which depend on special reliability, such as medical devices, in particular implants.
- Embodiments of the invention are also particularly advantageous because a relatively large inductance can be realized with a relatively small ohmic resistance and thus the reactive power and the waste heat are correspondingly low.
