摘要： A surface-mount inductor includes an element assembly having a core, a coil, and a magnetic material; and a pair of external terminals on a mounting surface of the element assembly. The core has a base portion and a columnar portion on an upper surface of the base portion. The coil is disposed on the base portion, and has a wound portion on the columnar portion, and a pair of extended portions extended from the wound portion. In a cross-section parallel to a winding axis, the wound portion has, in at least a part of a region where the upper stage and the lower stage are in contact with or oppose each other, a boundary surface formed by one portion of a conductive wire at one of upper and lower stage sides being in contact with or opposing a plurality of portions of the conductive wire at the other side.

摘要： A high frequency inductor filter cooling apparatus, method of manufacture, and method of use thereof is described. In one embodiment, an inductor is potted in an epoxy-silica mixture to facilitate thermal transfer from the inductor. The inductor is optionally used with a capacitor to filter/invert/convert power. The inductor optionally comprises a distributed gap core and/or a powdered core material. In one example, a minimum carrier frequency used with the filter is above that usable by a traditional wound iron-steel inductor, such as greater than seven hundred or ten thousand Hertz at fifty or more amperes. Optionally, the inductor is used in an inverter/converter apparatus in conjunction with a notched low-pass filter, a low pass filter combined with a notch filter and a high frequency roll off filter, and/or one or more of a silicon carbide, gallium arsenide, and/or gallium nitride based transistor.

摘要： An inductor includes a substrate as a base material, a core portion, a coil portion, an insulating portion formed between conductors of the coil portion, and a terminal portion connecting the core portion and the coil portion to the outside. A main direction of a magnetic field that is generated in accordance with current flowing through the coil portion extends in a planar direction of the substrate. In at least a portion of the coil portion, both width and thickness of a rectangular cross-sectional area of the coil portion are larger than the width of the insulating portion.

摘要： A method of forming an inductor assembly includes depositing a magnetic core on a planar substrate lying in a core plane, forming an inductor coil that generates a magnetic field that passes through the magnetic core in a closed loop parallel to the core plane, and annealing the magnetic core while applying an external magnetic field that passes through the magnetic core in a radial direction to permanently fix the easy axis of magnetization parallel to the radial direction. As a result, the hard axis of magnetization of the magnetic core is permanently oriented in a generally circular closed path parallel to the closed loop of the inductor's magnetic field.

摘要： According to some implementations, an apparatus for transmitting charging power wirelessly to a load is provided. The apparatus comprises at least one ferrite structure comprising a first ferrite portion, a second ferrite portion comprising at least a first ferrite leg, a second ferrite leg, and a third ferrite leg, each physically separated from the first ferrite portion by a first distance, and a third ferrite portion positioned between the second ferrite leg and the first ferrite portion and physically contacting the second ferrite leg. The at least one ferrite structure further comprises a coil wound around the second ferrite leg and configured to generate an alternating current under influence of an alternating magnetic field.

摘要： An electromagnetic coil assembly for a control rod driving mechanism, comprising coils and a yoke for embedding the coils, wherein damascene holes are disposed on the yoke, the coils are installed in the damascene holes, the yoke comprises first yokes and second yokes, and the damascene holes are disposed on the first yokes; the first yokes are connected with the second yokes, and a through hole for cooperating with a sealing shell assembly is disposed on the second yokes; and a thermal conductivity of the first yokes is stronger than a thermal conductivity of the second yokes. The method is the processing method of the assembly. The coil assembly provided in technical solution or the coil assembly obtained by the method can remarkably reduce the temperature inside the coil, thereby improving the reliability of the CRDM electromagnetic coil assembly and prolonging the service life of the CRDM electromagnetic coil assembly.

摘要： Inductive elements comprising anisotropic media and a bias coil for magnetically biasing thereof and methods of manufacture and operation for use in applications such as microelectronics. The bias coil generates a magnetic field that biases a magnetic core material during deposition thereof such that a desirable orientation of anisotropy is achieved throughout the magnetic core and enables modulation of the inductive response of the device. The bias coil can generate the magnetic field by application of electrical current therethrough. Alternatively, the bias coil can include or can be replaced with a permanent magnet that can generate the magnetic field without application of electrical current therethrough.
