Multilayer ceramic capacitor having high capacity and method of manufacturing the same

摘要

There are provide a multilayer ceramic capacitor and a method of manufacturing the same. The multilayer ceramic capacitor includes a multilayer body having a first side and a second side opposed to each other and having a third side and a fourth side connecting the first side to the second side, inner electrodes formed in the multilayer body and formed to be spaced apart from the third side or the fourth side by a predetermined distance, groove portions formed on at least one of top and bottom surfaces of the multilayer body and formed parallel to the third or fourth side by a predetermined distance from the third side or the fourth side, and outer electrodes extended from the third side and the fourth side to the top surface or the bottom surface of the multilayer body to cover the groove portions.

主权项

1. A multilayer ceramic capacitor, comprising:
a multilayer body having a first side and a second side opposed to each other and having a third side and a fourth side connecting the first side to the second side; first inner electrodes disposed in the multilayer body, each having one end exposed to the third side and the other end being disposed between the third side and the fourth side; second inner electrodes disposed in the multilayer body, each having one end exposed to the fourth side and the other end being disposed between the third side and the fourth side; first dummy electrodes, each being disposed at a substantially same level with a corresponding one of the first inner electrodes, each having one end exposed to the fourth side and an other end being spaced apart from the one of the first inner electrodes; second dummy electrodes, each being disposed at a substantially same level with a corresponding one of the second inner electrodes, each having one end exposed to the third side and another end being spaced apart from the one of the second inner electrodes; first and second side portions disposed on the first and second side of the multilayer body, each having a convex-shaped surface; outer electrodes disposed on the third side and the fourth side; and first and second main grooves disposed on at least one of the top and bottom surfaces of the multilayer body, wherein the central portion of the first main groove lies over the area between the first dummy electrodes and the first inner electrodes, the central portion of the second main groove lies over the area between the second dummy electrodes and the second inner electrodes, the first and second main grooves are formed under each outer electrode on each of the top or bottom surfaces of the multilayer body, only one main groove is formed under each outer electrode on each of the top or bottom surfaces of the multilayer body, and each outer electrode extends in a direction on the top or bottom surface of the multilayer body from either the third side or fourth side to beyond the main groove.
