Abstract
Dielectric patterns may be additionally disposed in margin portions, and thicknesses of the dielectric patterns may be controlled to improve the reliability of a capacitor component.
Claims19
A capacitor component comprising:
- a body including first and second dielectric layers, and having first and second surfaces opposing each other in a thickness direction, third and fourth surfaces connected to the first and second surfaces and opposing each other in a length direction, and fifth and sixth surfaces connected to the first to fourth surfaces and opposing each other in a width direction;
- a first internal electrode disposed on the first dielectric layer, exposed to the third surface, and spaced apart in the length and width directions from the fourth, fifth, and sixth surfaces by a first space;
- a second internal electrode disposed on the second dielectric layer and opposing the first internal electrode with the first or second dielectric layer interposed therebetween, exposed to the fourth surface, and spaced apart in the length and width directions from the third, fifth and sixth surfaces by a second space;
- a first dielectric pattern disposed in at least a portion of the first space, extending from the first space, and covering an end portion of the first internal electrode in the thickness direction;
- a second dielectric pattern disposed in at least a portion of the second space, extending from the second space, and covering an end portion of the second internal electrode in the thickness direction;
- and
- first and second external electrodes disposed on the third and fourth surfaces of the body, respectively, and electrically connected to the first and second internal electrodes, respectively,
- wherein, along the thickness direction, an average dielectric grain size of the first and second dielectric patterns is smaller than an average dielectric grain size of the first and second dielectric layers.
