Patent number: 11600441Abstract: A multilayer electronic component includes a body including dielectric layers and internal electrodes. The internal electrodes are exposed to fifth and sixth surfaces of the body, and first ends thereof are respectively exposed to third or fourth surfaces of the body. First and second side margin portions are respectively disposed on the fifth and sixth surfaces. The body includes an active portion, and upper and lower cover portions disposed respectively on a first surface and a second surface of the active portion in a first direction. The ratio of a dimension of the lower cover portion in the first direction C to a dimension of the first side margin portion in the third direction A, C/A?2.6, C/T is 0.080, where T is a dimension of the body in the first direction, and D<C where D is the dimension of the body in the first direction.Type: GrantFiled: April 5, 2021Date of Patent: March 7, 2023Assignee: SAMSUNG ELECTRO-MECHANICS CO., LTD.Inventors: Seung Min Kang, Ho Sam Choi, Jong Ho Lee, So Hyeon Hong
