MULTILAYER CERAMIC CAPACITOR |
摘要 |
The "squeal" that occurs when an electric field is applied to a multilayer ceramic capacitor mounted on a substrate is suppressed by providing in an active part contributing to formation of capacitances between internal electrodes facing each other in a capacitor body, low-activity regions positioned near respective end edges of respective external electrodes. A facing area of the internal electrodes in the low-activity regions is less than or equal to one fifth that of the internal electrodes in a normal region having the same volume as that of the low-activity regions. This makes it possible to suppress occurrence of electric-field-induced distortion near the external electrodes bonded to a substrate and reduce the force that causes the substrate to bend.
