A multilayer ceramic capacitor includes a ceramic body which is unlikely to be cracked. A dimension in a length direction L is referred to as L0. A distance in the length direction L is referred to as L1 between an end in the length direction L of a portion of a first external electrode located on a first principal surface and an end of a second internal electrode closer to the first end surface. The ratio L1/L0 is about 0.05 to about 0.35.

Multilayer ceramic capacitor and mounted structure with multilayer ceramic capacitor

A multilayer ceramic capacitor is configured such that 'a' is a distance in a height direction between an effective portion and a first principal surface; 'b' is a distance in a length direction between a first end surface and the effective portion in the length direction; &#x201c;c&#x201d; is a thickness of the thickest portion of a first base layer provided over the first principal surface; &#x201c;d&#x201d; is a distance in the length direction between the thickest portion of the first base layer provided over the first end surface and a portion of the first base layer located over the first principal surface and closest to a second end surface; and &#x201c;e&#x201d; is a maximum thickness of a portion of the first base layer provided over the first end surface; and f: the height of the ceramic body, and 2&#x2264;(c&#xb7;d+e&#xb7;f/2)/(a&#xb7;b)&#x2264;6 is satisfied.

A collective component has a first region that intersects with a conductive film for external terminal electrodes in a break line in which break leading holes are arranged and a second region that does not intersect with the conductive film for external terminal electrodes in the break line. The plurality of break leading holes includes at least one extending break leading hole located so as to extend over the first region and the second region.

Ceramic electronic component, method of manufacturing the same, and collective component

A collective component has a first region that intersects a conductive paste film for external terminal electrodes in a break line in which break leading holes are arranged and a second region that does not intersect a conductive paste film for external terminal electrodes in the break line. The first break leading holes are formed in the first region so as not to reach the second region. The second break leading holes are formed only in the second region or from the second region to a portion of the first region. The pitch of the first break leading holes is wider than the pitch of the second break leading holes.

In a monolithic ceramic capacitor, the size of end surfaces of a capacitor body in a two-dimensional surface in which ceramic layers extend is greater than the size of side surfaces in the two-dimensional surface in which the ceramic layers extend. External terminal electrodes include a resistive component. In each of first to fourth internal electrodes, a width-direction size of a lead-out portion is less than a width-direction size of a capacitance portion. The lead-out portions of the first and third internal electrodes and the lead-out portions of the second and fourth internal electrodes are arranged so as to partially overlap each other or not to overlap each other.

Monolithic ceramic capacitor

In an LW-reverse-type monolithic ceramic capacitor including external terminal electrodes each including a resistance component, internal electrodes include nickel or a nickel alloy, and the external terminal electrodes each include a first layer, a second layer provided on the first layer, and a third layer provided on the second layer. The first layer has a wrap-around portion extending from an end surface to principal surfaces and side surfaces of a capacitor main body, and contains a glass component and a compound oxide that reacts with Ni or the Ni alloy. The second layer covers the first layer such that the edge of the wrap-around portion of the first layer remains exposed, and contains a metal. The third layer covers the edge of the wrap-around portion of the first layer and the second layer, and is formed by plating.
