摘要
(US9570235) A multilayer ceramic capacitor that is highly resistant to insulation degradation under high-temperature load includes an inner ceramic layer that has a composition mainly composed of a perovskite-type compound containing Ba and Ti, at least one of Nb and Ta, contains Mn and Al, and optionally contains Mg and a rare-earth element that is at least one of Y, Gd, Tb, Dy, Ho, and Er, with a content of Ti being 100 parts by mole, and (a) a total of Nb and Ta is from about 0.2 to about 1.5 part by mole, (b) Mg is not more than about 0.2 part by mole including 0 part by mole, (c) Mn is from about 1.0 to about 3.5 parts by mole, (d) Al is from about 1.0 to about 4.0 parts by mole, and (e) the rare-earth element is not more than about 0.05 part by mole including 0 part by mole.  Furthermore, an average number of particles per one layer of the inner ceramic layer is not more than 3.
