Abstract: An inductor includes a coil substrate, an encapsulation material containing a magnetic material and selectively covering the coil substrate, and first and second external electrodes formed on the exterior of the encapsulation material. The coil substrate includes a laminate of stacked structures each including a conductive track and first and second connection parts on opposite sides of the conductive track in a single wiring layer. The conductive tracks are connected in series to form a helical coil. The first connection parts are connected by a first via to form a first electrode terminal connected to a first end of the helical coil. The second connection parts are connected by a second via to form a second electrode terminal connected to a second end of the helical coil. The first and second external electrodes are connected to the first and second electrode terminals, respectively.

Abstract: An inductance component includes a magnetic core (11, 12) forming a magnetic circuit having a magnetic gap, an exciting coil (14) wound around the magnetic core, and a permanent magnet (13) disposed in the magnetic gap. The permanent magnet is greater in sectional area than the magnetic core.

Abstract: An inductance component comprises a magnetic core having at least one magnetic gap, means for generating a direct-current biased magnetic field produced by mounting a permanent magnet in the vicinity of a generally closed magnetic circuit which passes through the magnetic gap in the magnetic core or on the outside thereof, and a coil wound around the magnetic core, wherein the permanent magnet is mounted near the magnetic gap at one or more legs of the magnetic core which sandwich the magnetic gap.

Abstract: An inductor component is provided which includes a magnetic core having at least one gap, an excitation coil disposed on the magnetic core so as to form a magnetic path on the magnetic core, at least one permanent magnet disposed near the at least one gap, and at least one first soft magnetic material piece disposed between the at least one permanent magnet and the magnetic core, wherein the first soft magnetic material piece is formed of a soft magnetic material which has a smaller permeability and less eddy current loss than the magnetic core.

Abstract: In an inductance component in which a cylindrical excitation coil (26) is fitted around a predetermined portion of a magnetic core (21) forming a magnetic path, a permanent magnet (25) is inserted into the magnetic path to apply a magnetic bias to the magnetic core. The permanent magnet is arranged outside the cylindrical excitation coil. It is preferable that the permanent magnet is spaced from the predetermined portion of the magnetic core along the magnetic path at least by a distance which corresponds to ½ of an average of inner diameters of the cylindrical excitation coil.

Abstract: An inductor component comprises a magnetic core having at least one gap, an excitation coil disposed on the magnetic core so as to form a magnetic path on the magnetic core, and permanent magnets disposed near at least one of the gaps. With this inductor component, the permanent magnets are disposed across from a first soft magnetic material piece formed of a soft magnetic material which has smaller permeability and less eddy current loss than the magnetic core. With this inductor component, few restrictions exist with regard to the form of the positioned permanent magnet, generation of heat of the permanent magnet due to the magnetic flux from the coil wound on the magnetic core is suppressed, and properties do not deteriorate.
