Abstract
An inductor assembly includes at least one inductor coil, a metallic inductor housing at least partially enclosing the inductor coil, and a potting material both contacting the inductor coil and the metallic inductor housing and thermally coupling the inductor coil to the metallic inductor housing. The inductor coil includes a bobbin made of electrically insulating material, and an inductor winding made of an electric conductor wound on the bobbin. The inductor winding further has an outer circumference and two end faces, and an electric insulation covers the outer circumference of the inductor winding. Coil lids made of electrically insulating material at least partially cover the end faces of the inductor winding and adjacent areas of the electric insulation covering the outer circumference of the inductor winding such that a distance of any point of the end faces of the inductor winding to the metallic housing along any way not passing through the electrically insulating material of the coil lids or the bobbin is at least a required minimum creepage distance.
