Abstract

A multilayer electronic component includes a body including a dielectric layer and first to fourth internal electrode layers disposed alternately in a first direction with the dielectric layer interposed therebetween; and first and second external electrodes disposed on the third and fourth surfaces respectively, wherein the internal electrode layer includes an internal electrode and a dummy electrode spaced apart from each other with a spacing portion therebetween, and at least two of the spacing portions may include regions overlapping each other in the first direction and other regions do not overlapping each other.

Claims (30)

1 . A multilayer electronic component, comprising:

a body including a dielectric layer and first to fourth internal electrode layers disposed alternately in a first direction with the dielectric layer interposed therebetween, the body including first and second surfaces opposing each other in the first direction, third and fourth surfaces connected to the first and second surfaces and opposing each other in a second direction, and fifth and sixth surfaces connected to the first to fourth surfaces and opposing each other in a third direction; and

first and second external electrodes disposed on the third and fourth surfaces respectively,

wherein the first internal electrode layer includes a first internal electrode, and a first dummy electrode spaced apart from the first internal electrode with a first spacing portion therebetween, the second internal electrode layer includes a second internal electrode, and a second dummy electrode spaced apart from the second internal electrode with a second spacing portion therebetween, the third internal electrode layer includes a third internal electrode, and a third dummy electrode spaced apart from the third internal electrode with a third spacing portion therebetween, and the fourth internal electrode layer includes a fourth internal electrode, and a fourth dummy electrode spaced apart from the fourth internal electrode with the fourth spacing portion therebetween,

wherein the first external electrode is connected to the first internal electrode, the third internal electrode, the second dummy electrode and the fourth dummy electrode, and the second external electrode is connected to the second internal electrode, the fourth internal electrode, the first dummy electrode, and the third dummy electrode, and

wherein the first spacing portion includes a region overlapping the third spacing portion in the first direction and a region not overlapping the third spacing portion, and the second spacing portion includes a region overlapping the fourth spacing portion in the first direction and a region not overlapping the fourth spacing portion.

2 . The multilayer electronic component of claim 1 ,

wherein each of the first to fourth internal electrodes includes first and second sides opposing each other in the third direction, and

wherein a length of the first side of each of the first to fourth internal electrodes is different from a length of the second side of each of the first to fourth internal electrodes, respectively.

3 . The multilayer electronic component of claim 1 ,

wherein each of the first to fourth dummy electrodes includes first and second sides opposing each other in the third direction, and

wherein a length of the first side of each of the first to fourth dummy electrodes is different from a length of the second side of each of the first to fourth dummy electrodes.

4 . The multilayer electronic component of claim 1 , wherein each of the first to fourth spacing portions has a substantially parallelogrammatic shape.

5 . The multilayer electronic component of claim 1 , wherein a size, in the second direction, of each of the first to fourth spacing portions is substantially constant.

6 . The multilayer electronic component of claim 1 , wherein an average size, in the second direction, of each of the first to fourth spacing portions is 15 μm or more and 200 μm or less.

7 . The multilayer electronic component of claim 1 , wherein the first to fourth internal electrodes are spaced apart from the fifth and sixth surfaces.

8 . The multilayer electronic component of claim 1 , wherein the first to fourth dummy electrodes are spaced apart from at least one of the fifth and sixth surfaces.

9 . The multilayer electronic component of claim 1 , wherein the first to fourth dummy electrodes are in contact with a portion of one of the fifth and sixth surfaces.

10 . The multilayer electronic component of claim 9 , wherein the first and fourth dummy electrodes are disposed to be in contact with a portion of the first surface, and the second and third dummy electrodes are disposed to be in contact with a portion of the sixth surface.

11 . The multilayer electronic component of claim 10 ,

wherein the first and second external electrodes are disposed to be in contact with portions of the fifth and sixth surfaces, respectively,

wherein a size, in the second direction, of the first external electrode, in contact with a portion of the fifth surface, is larger than the size, in the second direction, of the fourth dummy electrode, in contact with a portion of the fifth surface,

wherein a size, in the second direction, of the first external electrode, in contact with a portion of the sixth surface, is larger than a size, in the second direction, of the second dummy electrode, in contact with a portion of the sixth surface,

wherein a size, in the second direction, of the second external electrode, in contact with a portion of the fifth surface, is larger than a size, in the second direction, of the first dummy electrode, in contact with a portion of the fifth surface, and

wherein a size, in the second direction, of the second external electrode, in contact with a portion of the sixth surface, is larger than a size, in the second direction, of the third dummy electrode, in contact with a portion of the sixth surface.

12 . The multilayer electronic component of claim 1 , wherein each of the first to fourth internal electrodes includes an interior angle satisfying θ 1 , each of the first to fourth dummy electrodes includes an interior angle satisfying θ 2 , and θ 1 and θ 2 are each 30° or more and 80° or less.
