Patent ID: 7508290

Claim:
An inductive component for the formation of a magnetic circuit, comprising: at least one wire winding formed of a braided wire having 5 to 100 individual wires that are electrically insulated from one another, the individual wires having an individual wire diameter within the range of from 10 μm to 50 μm; at least one core formed of a ferromagnetic core material, the core having at least two symmetrical core parts which are opposed to each other and separated by gaps therein to interrupt the magnetic circuit, the gaps each having a gap width within the range of from 2.0 mm to 10 mm, inclusive, at least one of the gaps being an air gap, all of the gaps having an essentially equal gap width; a heat sink; and a cooling device to cool the wire winding, the cooling device comprising: a film formed of a first polymer-thermally conductive filler composite material, the film being in thermally conductive contact with the wire winding; and a casting compound formed of a second polymer-thermally conductive filler composite material different form the first polymer-thermally conductive filler composite material, the casting compound being in thermally conductive contact with the heat sink.
