Disclosed herein is an inductor component that includes a magnetic core having magnetic thin ribbons laminated in a z-direction, a first coil conductor inserted into first and second through holes penetrating the magnetic core in the z-direction, and a second coil conductor inserted into third and fourth through holes penetrating the magnetic core in the z-direction. Each of the magnetic thin ribbons is divided into a plurality of small pieces by net-shaped cracks. A periphery of each of the first to fourth through holes is surrounded by the plurality of small pieces without being circumferentially divided by a slit having a size larger than the crack.

The invention concerns a magnetic core device (1) to be used in a power converter (100), comprising at least one fixation leg (7), and a body (51) comprising a magnetic core (3). The at least one fixation leg (7) extends from the body (51), and is configured to firmly fixate the magnetic core device (1) to a target component (110) such as a housing (110) of the power converter (100). The at least one fixation leg (7) and the body (51) are integrally formed as one-piece.

The present embodiments relate to an inductor device, a filter device and a steering assist device. The inductor device can comprise: a core including a magnetic material; and a wire which is wound around the core and which includes a low resistance material.

A method of manufacturing a power semiconductor system includes providing a power module having one or more power transistor dies and attaching an inductor module to the power module such that the inductor module is electrically connected to a node of the power module. The inductor module includes a substrate with a magnetic material and windings at one or more sides of the substrate. Further methods of manufacturing power semiconductor systems and methods of manufacturing inductor modules are also described.

A microelectronics package comprising a package core and an inductor over the package core. The inductor comprises a dielectric over the package core. The dielectric comprises a curved surface opposite the package core. At least one conductive trace is adjacent to the package core. The at least one conductive trace is at least partially embedded within the dielectric and extends over the package core. A magnetic core cladding is over the dielectric layer and at least partially surrounding the conductive trace.

In large area plasma processing systems, process gases may be introduced to the chamber via the showerhead assembly which may be driven as an RF electrode. The gas feed tube, which is grounded, is electrically isolated from the showerhead. The gas feed tube may provide not only process gases, but also cleaning gases from a remote plasma source to the process chamber. The inside of the gas feed tube may remain at either a low RF field or a zero RF field to avoid premature gas breakdown within the gas feed tube that may lead to parasitic plasma formation between the gas source and the showerhead. By feeding the gas through an RF choke, the RF field and the processing gas may be introduced to the processing chamber through a common location and thus simplify the chamber design.

A dust core contains a powder of a crystalline magnetic material powder and a powder of an amorphous magnetic material. The sum of the content of the crystalline magnetic material powder and the content of the amorphous magnetic material powder is 83 mass percent or more. The mass ratio of the content of the crystalline magnetic material powder to the sum of the content of the crystalline magnetic material powder and the content of the amorphous magnetic material powder is 20 mass percent or less. The median diameter D50 of the amorphous magnetic material powder is greater than or equal to the median diameter D50 of the crystalline magnetic material powder.

An EMI filter for an inverter may include a choke including a magnetic inner core, a magnetic outer core, and at least one conductor pair. The at least one conductor pair may include an electrically conductive positive conductor and an electrically conductive negative conductor. The inner core, the outer core, the positive conductor, and the negative conductor may extend along a longitudinal central axis of the choke. The inner core may be arranged in the outer core. The positive conductor and the negative conductor may be arranged between the inner core and the outer core. The positive conductor and the negative conductor may be arranged spaced apart from one another in a circumferential direction extending around the longitudinal central axis. A gap may be formed between the inner core, the outer core, the positive conductor, and the negative conductor, which are adjacent in the circumferential direction.
