Title:
MULTILAYER INDUCTOR AND METHOD FOR MANUFACTURING THE SAME
Document Type and Number:
WIPO Patent Application WO/2009/136661
Kind Code:
A1
Abstract:
Disclosed is a multilayer inductor using an Ni-Zn-Cu ferrite, which has improved temperature characteristics and is free from structural defects. A method for manufacturing the multilayer inductor is also disclosed. The multilayer inductor is characterized by comprising: a multilayer body (1) having a rectangular solid shape, which comprises a plurality of magnetic layers (3, 3) composed of an Ni-Zn-Cu ferrite, a plurality of conductive layers (2, 2) forming a coil by being laminated via the magnetic layers, and at least one non-magnetic layer (4) so formed as to be in contact with the plurality of magnetic layers (3, 3) and composed of a Ti-Ni-Cu-Mn-Zr dielectric; and at least a pair of external electrodes (7, 7) arranged on the ends of the multilayer body (1) and electrically connected to the ends of the coil.
