Title:
LAMINATED COMMON MODE CHOKE COIL, AND HIGH-FREQUENCY COMPONENT
Document Type and Number:
WIPO Patent Application WO/2013/031873
Kind Code:
A1
Abstract:
 A primary coil is formed by the series connection of a first coil element (L1a), a second coil element (L1b) and a fifth coil element (L1c), and a secondary coil is formed by the series connection of a third coil element (L2a), a fourth coil element (L2b) and a sixth coil element (L2c). Certain coil elements (L1a, L2b, L1c) are arranged on the same axis as each other, and other coil elements (L2a, L1b, L2c) are arranged on the same axis as each other. The coil elements (L1a, L1b, L1c) of the primary coil and the coil elements (L2a, L2b, L2c) of the secondary coil are arranged so as to be adjacent to one-another in the lamination direction of a substrate layer. The coil elements are connected such that a magnetic field in the same direction is generated in all of the coil elements (L1a, L1b, L1c, L2a, L2b, L2c) when common mode current flows.
