Abstract
A multilayer ceramic capacitor includes a body including an active region including first and second internal electrodes, and an upper cover region disposed on the active region, and a lower cover region disposed below the active region. First and second external electrodes are disposed on first and second surfaces of the body in the length direction and connected to the first and second internal electrodes, respectively. At least one stress dispersion pattern occupying an area equal to 30% to 95% of an area of the first or second internal electrode is disposed in the cover region.
Claims7
A multilayer ceramic capacitor comprising:
- a body including an active region including a plurality of dielectric layers and first and second internal electrodes alternately disposed with at least one among the plurality of dielectric layers interposed therebetween to be alternately exposed to first and second surfaces of the body in a length direction, respectively, an upper cover region disposed on the active region, and a lower cover region disposed below the active region;
- and
- first and second external electrodes disposed on the first and second surfaces of the body in the length direction and connected to the first and second internal electrodes, respectively, wherein
- at least one stress dispersion pattern is disposed in at least one of the upper and lower cover regions, the stress dispersion pattern occupying an area within a range of 30% to 95% of an area of the first or second internal electrode,
- the at least one stress dispersion pattern includes first and second stress dispersion patterns alternately disposed in a stacking direction in the at least one of the upper and lower cover regions, and connected to the first and second external electrodes, respectively, and
- a length or width of the first and second stress dispersion patterns is increased from an outer portion of the body to a central portion of the body.
