Patent number: 9812245Abstract: In a laminated coil component, first coil conductor patterns define a coil opening that generates a magnetic flux in a first direction, second coil conductor patterns define a first coil opening that generates a magnetic flux in the first direction, and a second coil opening that generates a magnetic flux in a second direction. A difference in area between the first coil opening and the second coil opening determines a degree of coupling of the coil defined by the first coil conductor pattern and the coil defined by the second coil conductor pattern. This provides a close proximal arrangement of a plurality of coils proximally while significantly reducing or preventing unnecessary coupling between the coils.Type: GrantFiled: September 1, 2015Date of Patent: November 7, 2017Assignee: MURATA MANUFACTURING CO., LTD.Inventor: Kenichi Ishizuka
