20080231401 | EMBEDDED INDUCTOR AND MANUFACTURING METHOD THEREOF - A manufacturing method of an embedded inductor includes the steps of providing a magnetic plastic material, disposing at least one coil into a mold, and injecting or pressing the magnetic plastic material into the mold to form a magnetic body encapsulating the coil. An embedded inductor includes at least one magnetic body encapsulating the coil by injecting molding or pressing molding. | 09-25-2008 |
20080278273 | Inductor - An inductor includes a coil and a magnetic body. The magnetic body covers the coil. The magnetic body includes at least one magnetic material, at least one insulated magnetic material and at least one resin. The magnetic material is enveloped by the insulated magnetic material. Alternatively, the magnetic body is made by mixing the insulated magnetic material with the magnetic material. | 11-13-2008 |
20090051475 | EMBEDDED INDUCTOR AND MANUFACTURING METHOD THEREOF - An embedded inductor includes a coil and a magnetic body covering the coil. The magnetic body includes an insulated magnetic powder, a coupling agent and a resin. In addition, a manufacturing method of the embedded inductor includes steps of performing an insulation process for a magnetic powder to obtain an insulated magnetic powder; performing a surface process on the insulated magnetic powder; mixing the surface-processed insulated magnetic powder with a liquid resin to form a mixture; providing a coil; covering the coil with the mixture; and performing pressing and curing processes to obtain the embedded inductor. | 02-26-2009 |
20090051478 | FILTER AND MANUFACTURING METHOD THEREOF - A filter includes a first magnetic ring, a second magnetic ring, two windings and a magnetically conductive element. The second magnetic ring covers the first magnetic ring. The windings are wound around the second magnetic ring, respectively, and the magnetically conductive element is assembled with the second magnetic ring. | 02-26-2009 |
20090128248 | FILTER AND MANUFACTURING METHOD THEREOF - A filter includes a first magnetic layer, a second magnetic layer, an insulating layer, a plurality of coils, a first non-magnetic layer and a second non-magnetic layer. The insulating layer is disposed between the first magnetic layer and the second magnetic layer, and the coils are disposed in the insulating layer. The first non-magnetic layer is disposed on one side of the first magnetic layer, which is far away from the insulating layer, and the second non-magnetic layer is disposed on one side of the second magnetic layer, which is far away from the insulating layer. | 05-21-2009 |
20100026444 | MAGNETIC ELEMENT - A magnetic element includes a core, a coil and a magnetic shield. The coil is wound around the core. The magnetic shield that contains a Fe-based powder is used to cover the coil and at least a part of the core so as to reduce the noise interference on the magnetic element. | 02-04-2010 |
20100052835 | MAGNETIC ELEMENT - A magnetic element includes a pair of coil sets. Each of the coil sets includes a first coil having a plurality of first metallic lines, a second coil having a plurality of second metallic lines, and at least one conductive column electrically connected between the first coil and the second coil. The magnetic element further includes a package body for enclosing the pair of coil sets therein. | 03-04-2010 |
