Ceramic electronic component
A ceramic electronic component wherein outer electrode is placed over both end portions of a ceramic body. A first coating mainly containing Ni and a second coating containing Sn, solder, or the like are placed on a surface of the outer electrode. The outer electrode includes an end-surface portion and a side-surface turnover portion. The outer electrode includes a glass layer which is placed in a region within at least 5 μm in linear distance L from a covering end portion of the side-surface turnover portion in a direction toward the end-surface portion so as to be in contact with the ceramic body and which contains, at least, Si. The average thickness t of the glass layer is 3 μm to 10 μm. The content of a Si component is 11% by weight or more (preferably 40% by weight or less).
FILM CAPACITOR
The present disclosure discloses a film capacitor, including: a capacitor core; a positive electrode busbar; a negative electrode busbar, superposed with and insulated from the positive electrode busbar; a first electrode terminal, connected to the positive electrode busbar; a second electrode terminal, connected to the negative electrode busbar; a first connection sheet connected to the positive electrode busbar and provided with a first connection terminal connected to the capacitor core; and a second connection sheet, opposed to the first connection sheet, connected to the negative electrode busbar and provided with a second connection terminal connected to the capacitor core, wherein the capacitor core is disposed between the first connection sheet and the second connection sheet; the first connection sheet, the first connection terminal and the positive electrode busbar are integrally formed; and the second connection sheet, the second connection terminal and the negative electrode busbar are integrally formed.
Plated terminations
Improved termination features for multilayer electronic components are disclosed. Monolithic components are provided with plated terminations whereby the need for typical thick-film termination stripes is eliminated or greatly simplified. Such termination technology eliminates many typical termination problems and enables a higher number of terminations with finer pitch, which may be especially beneficial on smaller electronic components. The subject plated terminations are guided and anchored by exposed internal electrode tabs and additional anchor tab portions which may optionally extend to the cover layers of a multilayer component. Such anchor tabs may be positioned internally or externally relative to a chip structure to nucleate additional metallized plating material. External anchor tabs positioned on top and bottom sides of a monolithic structure can facilitate the formation of wrap-around plated terminations.
