Abstract

A capacitor component includes a body including dielectric layers, first and second internal electrodes, laminated in a first direction, facing each other, and first and second cover portions, disposed on outermost portions of the first and second internal electrodes, and first and second external electrodes, respectively disposed on both external surfaces of the body in a second direction, perpendicular to the first direction, and respectively connected to the first and second internal electrodes. An indentation is disposed at at least one of boundaries between the first internal electrodes and the first external electrode or one of boundaries between the second internal electrodes and the second external electrode.

Claims (20)

1. A capacitor component comprising:

a body including dielectric layers, first and second internal electrodes, laminated in a first direction, facing each other, and first and second cover portions, disposed on outermost portions of the first and second internal electrodes; and

first and second external electrodes, respectively disposed on both external surfaces of the body in a second direction, perpendicular to the first direction, and respectively connected to the first and second internal electrodes,

wherein plural indentations are disposed at at least one of boundaries between at least one of the first internal electrodes and the first external electrode or one of boundaries between at least one of the second internal electrodes and the second external electrode.

2. The capacitor component of claim 1 , wherein the plural indentations are disposed at outermost boundaries of the body in the first direction, among the boundaries between the first internal electrodes and the first external electrode and the boundaries between the second internal electrodes and the second external electrode.

3. The capacitor component of claim 1 , wherein the plural indentations are disposed at boundaries between the first internal electrodes and the first external electrode and boundaries between the second internal electrodes and the second external electrode.

4. The capacitor component of claim 1 , wherein a sum of widths of the plural indentations in one of the first and second internal electrodes ranges from 30% to 80% of an overall width of the one of the first and second internal electrode.

5. The capacitor component of claim 1 , wherein at least one of the plural indentations has a dimension of 5 μm or less.

6. The capacitor component of claim 1 , wherein each of the dielectric layers has an average thickness of 0.4 μm or less.

7. The capacitor component of claim 1 , wherein the first and second cover portions have an average thickness of 0.4 μm or less.

8. The capacitor component of claim 1 , wherein each of the first and second cover portions has a thickness of 25 μm or less.

9. The capacitor component of claim 1 , wherein each of the first and second external electrodes comprises:

an electrode layer disposed on the body and a plating layer disposed on the electrode layer.

10. The capacitor component of claim 9 , wherein a metal oxide is disposed on a boundary between the external electrode layer and the plating layer.

11. The capacitor component of claim 10 , wherein the metal oxide has one of an island, a plurality of metal oxide bumps, an amorphous metal oxide, or a metal oxide powder.

12. The capacitor component of claim 9 , wherein a central portion of the electrode layer has a thickness ranging from 1 μm to 10 μm.

13. The capacitor component of claim 9 , wherein the electrode layer includes a glass material.

14. The capacitor component of claim 9 , wherein a central portion of the plating layer has a thickness ranging from 3 μm to 5 μm.

15. The capacitor component of claim 9 , wherein the plating layer includes nickel.

16. The capacitor component of claim 1 , wherein at least one of the plural indentations includes a groove.
