Abstract
A laminated ferrite chip inductor array wherein the array is composed in that multiple layers of ferrite sheets printed with U-shaped patterns of internal conductors are piled in such a manner that the U-shaped patterns of the internal conductors on adjacent sheets are opposed one another, and a plurality of channels composed by sintering the piled layers of coil-shaped structure of the internal conductive printed patterns made electrically communicating via through holes pierced in the ferrite sheets are held in ferrite porcelains, characterized in that the internal conductive pattern shapes of the adjacent chip inductors are turned 180 degree one another.
