Title:
MULTILAYER CERAMIC ELECTRONIC COMPONENT AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2012/002133
Kind Code:
A1
Abstract:
Disclosed is a multilayer ceramic electronic component comprising a coil conductor, wherein the number of laminated ceramic layers can be reduced without sacrificing the performance of the coil and the number of turns of the coil can be increased without causing growth in size. Specifically disclosed is a multilayer ceramic electronic component in which a coil conductor that has more than one turn per one ceramic layer is formed. The coil conductor comprises surface coil conductors (14, 19, 24, 29) that are positioned along the respective surfaces of sequentially laminated ceramic layers (2-1 to 2-4) and internal coil conductors (17, 22, 27, 32) that are positioned inside the ceramic layers so that each internal coil conductor does not exceed the thickness of one ceramic layer. The surface coil conductors and the internal coil conductors are connected in series via connecting parts (16, 21, 26, 31).
