  • Publication number: 20120018205
    Abstract: A method of manufacturing a ceramic electronic component prevents variations in characteristics even when the ceramic electronic component is embedded in a wiring board. Ceramic green sheets containing an organic binder having a degree of polymerization in a range from about 1000 to about 1500 are prepared. A first conductive paste layer is formed on a surface of each of the ceramic green sheets. The ceramic green sheets are laminated to form a raw ceramic laminated body. A second conductive paste layer is formed on a surface of the raw ceramic laminated body. The raw ceramic laminated body formed with the second conductive paste layer is fired.

  • Publication number: 20120019099
    Abstract: A ceramic electronic component includes a ceramic base, first and second internal electrodes, and first and second external electrodes. The first external electrode is disposed at a first end portion of a first major surface in the longitudinal direction. The second external electrode is disposed at a second end portion of the first major surface in the longitudinal direction. A portion of each of the first and second external electrodes is opposed in the thickness direction to a region where the first and second internal electrodes are opposed to each other in the thickness direction. A condition ( 1/10)t0?t1?(?)t0 is satisfied, where t0 is the thickness of each of the first and second external electrodes and t1 is the thickness of a portion in which each of the first and second external electrodes is embedded in the first major surface.

  • Publication number: 20120018204
    Abstract: A ceramic electronic component includes a ceramic element body having a substantially rectangular parallelepiped shape, and first and second external electrodes. The first and second external electrodes are provided on a first principal surface. Portions of the first and second external electrodes project further than the other portions in a thickness direction. A projecting portion of the first external electrode is provided at one end of the first external electrode in a length direction and a second projecting portion of the second external electrode is provided at another end of the second external electrode in the length direction. Thus, a concave portion is provided between the projecting portions, and a portion of the first principal surface provided between the first and second external electrodes is exposed.

  • Publication number: 20110290542
    Abstract: A ceramic electronic component includes a ceramic element assembly and external electrodes. The external electrodes are disposed on the ceramic element assembly. The external electrodes include an underlying electrode layer and a first Cu plating film. The underlying electrode layer is disposed on the ceramic element assembly. The first Cu plating film is disposed on the underlying electrode layer. The underlying electrode layer includes a metal that is diffusible in Cu and a ceramic bonding material. The metal that is diffusible in Cu is diffused in at least a surface layer in the underlying electrode layer side of the first Cu plating film.

  • Publication number: 20110293894
    Abstract: A ceramic electronic component includes a ceramic body having a substantially rectangular parallelpiped shape. The ceramic body includes a central portion in which first and second internal electrodes are arranged, and first and second end portions in which the first and second internal electrodes are not arranged. The ceramic electronic component satisfies Expressions (1) and (2) below: W1>T??(1) W2>T??(2) where T denotes the dimension of the ceramic body in a thickness direction, W1 denotes the dimension of the first end portion in a width direction, and W2 denotes the dimension of the second end portion in the width direction.

  • Publication number: 20100123994
    Abstract: In a ceramic electronic component having a thin structure, the occurrence of cracks due to stress applied when the ceramic component is being mounted or in a mounted state are prevented. Each of first and second external terminal electrodes has a substantially rectangular region on a principal surface of a ceramic element body, the principal surface being directed to the mounting surface side. An end of the first external terminal electrode, which is arranged in contact with a gap region, and an end of the second external terminal electrode, which is positioned in contact with the gap region, each preferably have a concave-convex shape on the principal surface.
