Abstract

A multilayer ceramic electronic component includes a ceramic body comprising dielectric layers and first and second internal electrodes laminatedly disposed in a third direction with respective dielectric layers interposed therebetween, and first electrode and second external electrodes disposed on both surfaces of the ceramic body in the first direction and electrically connected to the first and second internal electrodes. When an absolute value of a horizontal angle in the second direction of the first internal electrode with respect to the first surface of the ceramic body is referred to a first angle of the internal electrode, a total sum of the first angles is less than 10°.

First claim

What is claimed is:

1. A multilayer ceramic capacitor, comprising:
a ceramic body comprising dielectric layers and first and second internal electrodes laminated in a third direction with respective dielectric layers interposed therebetween, and first and second surfaces opposing each other in a direction in which the first and second internal electrodes are laminated, third and fourth surfaces connected to the first and second surfaces and opposing each other in a first direction, and fifth and sixth surfaces connected to the first and second surfaces and the third and fourth surfaces and opposing each other in a second direction; and
first and second external electrodes disposed on both surfaces of the ceramic body in the first direction, the first and second external electrodes being connected to the first and second internal electrodes,
wherein, when an absolute value of a horizontal angle in the second direction of the first internal electrode with respect to the first surface of the ceramic body is referred to as a first angle of the internal electrode, a sum of the absolute values of the first angles of outermost internal electrodes, disposed in an outermost part of the ceramic body in the third direction, among the first internal electrodes is 5° or less.

2. The multilayer ceramic capacitor of claim 1 , wherein the total sum of the first angles exceeds 0°.

3. The multilayer ceramic capacitor of claim 1 , wherein a maximum value of the first angles is 3° or less.

4. The multilayer ceramic capacitor of claim 1 , wherein a maximum value of the first angles is 1° or less.

5. The multilayer ceramic capacitor of claim 1 , wherein the first and second internal electrodes have a thickness in a range from 0.01 μm to 0.4 μm.

6. The multilayer ceramic capacitor of claim 1 , wherein ends of outermost internal electrodes, respectively disposed in an uppermost part and a lowermost part of the ceramic body in the third direction, among the second internal electrodes, are bent towards a center portion of the ceramic body in the third direction.

7. A multilayer ceramic capacitor, comprising:
a ceramic body comprising dielectric layers and first and second internal electrodes laminated in a third direction with respective dielectric layers interposed therebetween, and first and second surfaces opposing each other in a direction in which the first and second internal electrodes are laminated, third and fourth surfaces connected to the first and second surfaces and opposing each other in a first direction, and fifth and sixth surfaces connected to the first and second surfaces and the third and fourth surfaces and opposing each other in a second direction; and
first and second external electrodes disposed on both surfaces of the ceramic body in the first direction, the first and second external electrodes being connected to the first and second internal electrodes,
wherein, when an absolute value of a horizontal angle in the second direction of the second internal electrode with respect to the first surface of the ceramic body is referred to a second angle of the internal electrode, a sum of the absolute values of the second angles of outermost internal electrodes, disposed in an outermost part of the ceramic body in the third direction, among the second internal electrodes is 5° or less.

8. The multilayer ceramic capacitor of claim 7 , wherein the total sum of the second angles exceeds 0°.

9. The multilayer ceramic capacitor of claim 7 , wherein a maximum value of the second angles is 3° or less.

10. The multilayer ceramic capacitor of claim 7 , wherein a maximum value of the second angles is 1° or less.

11. The multilayer ceramic capacitor of claim 7 , wherein the first and second internal electrodes have a thickness in a range from 0.01 μm to 0.4 μm.

12. The multilayer ceramic capacitor of claim 7 , wherein ends of outermost internal electrodes, respectively disposed in an uppermost part and a lowermost part of the ceramic body in the third direction, among the second internal electrodes, are bent towards a center portion of the ceramic body in the third direction.
