Zusammenfassung:A wire wound inductor includes a winding coil, a magnetic core disposed in a central portion of the winding coil, and a body part filling a space around the winding coil and the magnetic core. The magnetic core has different characteristics from those of the body part, for example a higher permeability and higher magnetic flux density. In a method of manufacturing a wire wound inductor, a magnetic core is inserted in a central portion of a winding coil, wherein the magnetic core has different characteristics from those of a magnetic metal powder that is filled on the winding coil and the magnetic core. In one example, the filled magnetic metal powder is compressed at a pressure lower than a high pressure applied in the formation of the magnetic core.
