Abstract

A magnetic component is provided which has excellent DC overlay properties and is capable of suppressing leakage flux. The magnetic component includes: ferrite cores 100U, 100D each having two protruding components 104L, 104R; a ferrite core 110L disposed between one of the projecting members 104L of the ferrite cores 100U, 100D via the spacer 200L; a ferrite core 110R disposed via another spacer 200R between another of the protruding members 104R of the ferrite cores 100U, 100D; a coil 300L arranged so that the ferrite core 110L is located on an inner peripheral side thereof; and a coil 300R arranged so that the ferrite core 110R is located on an inner peripheral side thereof, the spacers 200L being located on the inner peripheral side of the coil 300L and the spacers 200R being located on the inner peripheral side of the coil 300R.

Description

technical field [0001] This invention relates to magnetic parts. Background technique [0002] In general, magnetic components used as reactors are constructed by combining simple I-shaped ferrite cores such as plate-shaped or column-shaped ferrite cores in consideration of ease of manufacture of magnetic components. For example, when paying attention to the ferrite core used in the magnetic component disclosed in Patent Document 1, the magnetic component has a first ferrite core and a second ferrite core arranged to face each other, and a spacer is interposed therebetween. A third ferrite core disposed between one end of the first ferrite core and one end of the second ferrite core, and the other end of the first ferrite core via a spacer and the fourth ferrite core between the other end of the second ferrite core. Also, each of the four ferrite cores has an I shape. In addition, in the magnetic component disclosed in Patent Document 1, a ferrite core having a higher res...
