An inductive component, for the formation of a magnetic circuit has at
least one wire winding and at least one core with a ferromagnetic core
material. The core comprises a gap and at least one further gap to
interrupt the magnetic circuit. The inductive component is characterized
in that the gaps each have a gap width of at least 1.0 mm. The core
comprises two pieces, for example, which are arranged opposed to each
other across the gaps and separated from each other by the gap width. The
component is advantageously symmetrical with an essentially equal gap
width for the gaps. A miniaturized inductive component is possible by the
use of a hire winding made from high frequency braided wire and core
material capable of accepting high frequencies, which has a high Q-factor
even on a high power throughput and thus low electrical losses. In order
to increase the Q-factor, the inductive component also has a cooling
device for cooling the wire winding. The device is thus provided with a
composite material with a thermally-conducting filler. The inductive
component is used in a so-called electronic ballast (EVG) in the field of
illumination.
