摘要： The present invention relates to a method (100) for manufacturing of a thermally conductive electrical component (20) comprising:
- providing (101) a thermally conductive thermoplastic material (10);
- processing (102) the thermally conductive thermoplastic material (10) by applying an extrusion-based 3D printing process to the thermally conductive thermoplastic material (10), wherein the step of processing (102) includes setting a printing path (12) of the thermally conductive thermoplastic material (10) during the 3D printing process in such a way that a flow direction (13) of the thermally conductive thermoplastic material (10) corresponds to a preferred direction (14) of a heat flow of the thermally conductive electrical component (20).

摘要： An inductor (100) is described. The inductor (100) includes a winding (110) and a magnetic core (120). The winding (110) has an axis (112), and a first planar surface (114) essentially orthogonal to the axis (112). The winding (110) defines an inner volume. The magnetic core (120) is form-fit into the inner volume. The core (120) includes a powdered magnetic material.
