Abstract
The invention relates to an inductive component () whose soft magnetic core () is produced by pouring a casting resin into a mold () filled with a soft magnetic alloy powder and by subsequently hardening the casting resin with the alloy powder in order to form a solid soft magnetic core. Contrary to conventional injection molding methods, this technique prevents the surface insulation of the alloy particles from becoming damaged so that the formation of bulk eddy currents in the resulting soft magnetic cores can be prevented to a large extent. This enables a distinct reduction in the electric loss of the inductive component.
