  • Patent number: 7969266
    Abstract: Provided is an inductor capable of adjusting an inductance in dozens of nH increments without requiring a large number of components. The inductor includes: a conductor; a first core body and a second core body each having an opposed surface, the opposed surface of the first core body and the opposed surface of the second core body facing each other so as to enclose the conductor; and a holding part provided with a slide surface for varying an opposed area of the opposed surfaces of the first core body and the second core body, for holding at least one of the first core body and the second core body at a desired position.

  • Patent number: 7449985
    Abstract: A problem to be solved is to stabilize temperature characteristics in various characteristics of a magnetic element. A magnetic element has a coil formed by winding a conductor, EP cores constituted of a magnetic material and passing magnetic flux generated in the coil, a solid part provided between EP cores opposing each other among the EP cores, and having a ceramics material or a resin material, in which the solid part is in contact with opposing faces of the respective opposing EP cores, and the solid part is provided with a thickness dimension ranging from 3 ?m to 30 ?m.

  • Patent number: 7345566
    Abstract: A magnetic element capable of obtaining a desired characteristic and at the same time having high productivity that enables cost reduction is provided. The magnetic element includes a first coil (50) to which a signal is inputted, a second coil (60) to which the signal inputted to the first coil (50) is transmitted, and includes a first core (20) having a first columnar leg portion (26) on which the first coil (50) is wound and a first peripheral wall portion (22, 23, 24) arranged on the periphery of the first columnar leg portion (26), and a second core (30) having a second columnar leg portion (36) on which the second coil (60) is wound and a second peripheral wall portion (32, 33 34) arranged on the periphery of the second columnar leg portion (36).
