Patents Assigned to TDK XIAMEN CO., LTD.
  • Publication number: 20220148808
    Abstract: A ceramic electronic component including: a ceramic element body including an end surface extending along a first axis, and a side surface extending along a second axis and intersecting the end surface; an end-face electrode formed on the end surface of the ceramic element body; and a lead terminal connected to the end-face electrode by soldering. The lead terminal includes: an adjacent part overlapping the end-face electrode in a side view from the second axis; and an extension part extending from an end of the adjacent part in a direction away from a plane including the side surface. A first recess is formed at the extension part and is recessed in a direction away from a plane including the end surface, and the first recess exists at a position close to the end of the adjacent part.

  • Patent number: 10343930
    Abstract: The present invention relates to the dielectric composition including barium titanate, strontium titanate, titanium oxide and bismuth oxide. In case when the content of barium titanate, converted to BaTiO3, is a mol %, the content of strontium titanate, converted to SrTiO3, is b mol %, the content of titanium oxide and bismuth oxide, converted to Bi2Ti3O9, is c mol %, and a+b+c=100, a, b and c are values within a scope surrounded by the following four points, i.e. point A, point B, point C and point D in a three-dimensional phase diagram. Point A: (a, b, c)=(52.1, 40.0, 7.9); point B: (a, b, c)=(86.5, 5.6, 7.9); point C: (a, b, c)=(91.0, 5.6, 3.4); point D: (a, b, c)=(56.6, 40.0, 3.4).
