摘要： A multilayer ceramic capacitor includes a multilayer body including dielectric layers which are stacked and internal electrode layers which are stacked, and external electrodes, each connected to the internal electrode layers. The external electrodes each include a conductive resin layer and a plated layer on the conductive resin layer. The conductive resin layer includes a resin portion, conductive fillers dispersed in the resin portion, and metal particles dispersed unevenly in a distribution differing from that of the conductive fillers in the conductive resin layer. An abundance ratio of the metal particles to the resin portion is higher on a side of the plated layer of the conductive resin layer than on a side of the conductive resin layer close to the multilayer body.

摘要： A multilayer ceramic capacitor includes a laminate including dielectric layers and internal electrode layers, and first and second external electrodes on surfaces of the laminate. The laminate includes first and second main surfaces oppose each other in a lamination direction, first and second side surfaces oppose each other in a length direction perpendicular or substantially perpendicular to the lamination direction, and third and fourth side surfaces oppose each other in a width direction perpendicular or substantially perpendicular to the lamination direction and the length direction. A length ratio EB1/EA1 of the first external electrode wrapping around to main surfaces of the laminate is about 0 or more and about 0.5 or less. A length ratio EB2/EA2 of the second external electrode wrapping around to the main surfaces of the laminate is about 0 or more and about 0.5 or less.

摘要： A multilayer ceramic electronic component includes a first plating layer in contact with a first organic layer and a second plating layer in contact with a second organic layer. When the first organic layer disposed on a first base electrode layer located on a first principal surface or a second principal surface, or the second organic layer disposed on a second base electrode layer located thereon, is referred to as an organic layer principal surface portion, and when the first organic layer disposed on the first base electrode layer located on a first end surface or a second end surface, or the second organic layer disposed on the second base electrode layer located thereon, is referred to as an organic layer end surface portion, the surface roughness of the organic layer end surface portion is larger than the surface roughness of the organic layer principal surface portion.

摘要： An electronic component includes a main body, first and second external electrodes, and a water-repellent film. The first and second external electrodes are provided on a portion of a surface of the main body. The water-repellent film is provided on another portion of the surface of the main body and on a surface of the first external electrode. The water-repellent film contains a non-cross-linked silicone resin. An angle of contact of water of about 25° C. with the water-repellent film is not less than about 100° and not greater than about 160°.

摘要： A multilayer ceramic capacitor includes: a laminate including dielectric layers and internal electrode layers; and external electrodes on the main surfaces of the laminate. The laminate further includes a first via conductor, a second via conductor, a third via conductor, and a fourth via conductor that connect the internal electrode layers and the external electrodes. The external electrodes include first external electrodes, second external electrodes, third external electrodes, and fourth external electrodes, each connected to the respective end surfaces of the via conductor. Each of the external electrodes does not extend to the side surfaces of the laminate. A ratio W/L of a dimension W in the width direction of the multilayer ceramic capacitor to a dimension L in the length direction of the multilayer ceramic capacitor is about 0.85 or more and about 1 or less. The dimension L in the length direction of the multilayer ceramic capacitor is about 750 μm or smaller.

摘要： A multilayer ceramic capacitor includes a ceramic element body including ceramic layers and internal electrode layers, and a pair of external electrodes on both end surfaces of the ceramic element body so as to be electrically connected to the internal electrode layers. Each of the external electrodes includes a base electrode layer and a resin external electrode layer stacked on the base electrode layer. The resin external electrode layer includes a thermosetting resin and a metal powder and amine, isocyanate, epoxy, mercapto, and/or ureido silane coupling agents.
