摘要:
The invention relates to a current-compensated choke, comprising a plurality of current paths (1, 2) and being made of a plurality of windings (1a, 1b, 2a, 2b) that are connected in parallel and are wound around a common core (3). The windings (1a, 1b, 2a, 2b) are preferably wound around the core (3) in an alternating way such that windings (1a, 1b, 2a, 2b) of a common current path (1, 2) are not arranged directly on top of each other.
摘要:
A low-loss ferrite comprising as main components 46.5-49.5% by mol of Fe 2 O 3 , 17-26% by mol of ZnO, 4-12% by mol of CuO, and 0.2% or more and less than 1.2% by mol of CoO, the balance being NiO, and 0.03-1.4% by mass (as SnO 2 ) of Sn based on 100% by mass of the main components, and having an average crystal grain size of 0.7-2.5 µm, and an electronic device obtained by integrally sintering pluralities of layers of this low-loss ferrite and coil-shaped electrodes formed in the laminate.
摘要:
Disclosed is a method for producing a magnetic core for antenna wherein thin metal strips are laminated. This method for producing a magnetic core for antenna is characterized in that a metal thin band is processed into strips having a width of the aimed magnetic core for antenna, then the thin strips are stacked through a resin layer to form a laminate, and after that the laminate is cut into a length of the aimed magnetic core for antenna.
