Abstract

There is provided a multilayer ceramic electronic component, including: a ceramic body including a dielectric layer and having first and third surfaces opposing each other in a length direction of the dielectric layer and second and fourth surfaces opposing each other in a width direction thereof; and a multilayer part including a first internal electrode and a second internal electrode disposed to oppose each other, while having the dielectric layer interposed there between in the ceramic body, and exposed to the first and third surfaces of the ceramic body, respectively; wherein one or more residual carbon removing path parts are formed to be protruded on both side of the first and second internal electrodes in a length direction of the ceramic body.

First claim

What is claimed is:

1. A multilayer ceramic electronic component, comprising:
a ceramic body including a dielectric layer and having first and third surfaces opposing each other in a length direction of the dielectric layer and second and fourth surfaces opposing each other in a width direction thereof;
a multilayer part including a first internal electrode and a second internal electrode disposed to oppose each other, while having the dielectric layer interposed therebetween in the ceramic body, and exposed to the first and third surfaces opposing each other in a length direction of the ceramic body, respectively; and
first and second external electrodes disposed on the first and third surfaces opposing each other in a length direction of the ceramic body,
wherein one or more residual carbon removing path parts are formed to be protruded from both sides of the first and second internal electrodes in a width direction of the ceramic body, and exposed to the second and fourth surfaces opposing each other in a width direction thereof, respectively,

wherein the multilayer ceramic electronic component further comprises a margin part including epoxy to cover the second and fourth surfaces opposing each other in a width direction of the ceramic body to which the residual carbon removing path parts are exposed, and
wherein the residual carbon removing path parts are provided in plural, and the plurality of residual carbon removing path parts are spaced apart from each other by predetermined intervals on both sides of the first and second internal electrodes.

2. The multilayer ceramic electronic component of claim 1 , wherein the residual carbon removing path parts have a length smaller than those of the first and second internal electrodes in the length direction of the ceramic body.

3. The multilayer ceramic electronic component of claim 2 , wherein the residual carbon removing path parts exposed to the second surface and the residual carbon removing path parts exposed to the fourth surface are symmetrical with regard to each other in a cross-section of the ceramic body in width-length directions.

4. The multilayer ceramic electronic component of claim 1 , wherein the residual carbon removing path parts are respectively exposed to the second and fourth surfaces, and
the residual carbon removing path parts exposed to the second and fourth surfaces are disposed to be offset from each other in a cross-section of the ceramic body in width-length directions.

5. The multilayer ceramic electronic component of claim 1 , wherein the margin part includes nonconductive powder formed of any one selected from a group consisting of aluminum oxide and silicon oxide.

6. The multilayer ceramic electronic component of claim 1 , wherein the margin part has a width of 200 μm or less in the width direction of the ceramic body.

7. A multilayer ceramic electronic component, comprising:
a ceramic body including a dielectric layer and having first and third surfaces opposing each other in a length direction of the dielectric layer and second and fourth surfaces opposing each other in a width direction thereof;
a multilayer part including a first internal electrode and a second internal electrode disposed to oppose each other, while having the dielectric layer interposed therebetween in the ceramic body, and exposed to the first and third surfaces opposing each other in a length direction of the ceramic body, respectively; and
first and second external electrodes disposed on the first and third surfaces opposing each other in a length direction of the ceramic body,
wherein one or more residual carbon removing path parts are formed to be protruded from both sides of the first and second internal electrodes in a width direction of the ceramic body, and exposed to the second and fourth surfaces opposing each other in a width direction thereof, respectively,

wherein the multilayer ceramic electronic component further comprises a margin part including epoxy to cover the second and fourth surfaces opposing each other in a width direction of the ceramic body to which the residual carbon removing path parts are exposed, and
wherein the residual carbon removing path parts are formed on one of both sides of the first and second internal electrodes, and alternately exposed to the second and fourth surfaces according to an order in which the first and second internal electrodes are stacked.
