Abstract
A multilayer ceramic capacitor has a cuboid or substantially cuboid multilayer body including a stack of dielectric layers, inner-electrode layers alternating with the dielectric layers and exposed at end surfaces of the multilayer body, and outer electrodes on the end surfaces and coupled to the inner-electrode layers. The dielectric layers are primarily made of barium titanate. At the interfaces between the dielectric and inner-electrode layers, protective layers containing calcium zirconate cover the inner-electrode layers.
