Abstract
Official abstract text for this publication.
A method of manufacturing a multilayer ferrite bead includes steps of: preparing ferrite sheets having internal electrodes formed on surfaces thereof; forming a ferrite laminate by stacking the ferrite sheets; forming a groove by pressurizing a central portion of the ferrite laminate; and forming external electrodes on the ferrite laminate.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method of manufacturing a multilayer ferrite bead, the method comprising steps of: preparing ferrite sheets having internal electrodes formed on surfaces thereof; forming a ferrite laminate by stacking the ferrite sheets; forming a groove by pressurizing a central portion of the ferrite laminate; and forming external electrodes on the ferrite laminate. 2 . The method of claim 1 , wherein the groove has a depth corresponding to 1% to 10% of a thickness of the ferrite laminate. 3 . The method of claim 1 , wherein the internal electrodes are connected to each other through a via to form a coil. 4 . The method of claim 3 , wherein the internal electrodes are electrically connected to the external electrodes. 5 . The method of claim 1 , wherein the external electrodes are formed by a dipping process or a wheel process. 6 . The method of claim 1 , further comprising a step of cutting and sintering the ferrite laminate, after the forming of the groove by pressurizing the central portion of the ferrite laminate. 7 . A multilayer ferrite bead comprising: a ferrite laminate comprising a plurality of ferrite sheets having internal electrodes formed on surfaces thereof; and external electrodes on the ferrite laminate, wherein the ferrite laminate includes a groove disposed in a central portion of the ferrite laminate. 8 . The multilayer ferrite bead of claim 7 , wherein the groove has a depth corresponding to 1% to 10% of a thickness of the ferrite laminate.
