Publication number: 20250218689Abstract: A multilayer electronic component includes a body including a plurality of dielectric layers, internal electrodes, and a reinforcing pattern and an external electrode on the body. The internal electrodes are disposed alternately with the dielectric layer therebetween in the first direction. The reinforcing pattern is disposed on surfaces of a capacitance formation portion in the first direction. The reinforcing pattern contacts a surface of the body in a second direction. The reinforcing pattern includes four parts in a third direction from one end to the other end in the third direction. A length of the reinforcing pattern at a ¼ point in the second direction is greater than a length thereof at a ½ point in the second direction and a length thereof at a ¾ point in the second direction is greater than the length thereof at the ½ point in the second direction.Type: ApplicationFiled: December 23, 2024Publication date: July 3, 2025Applicant: SAMSUNG ELECTRO-MECHANICS CO., LTD.Inventors: Jung Wun HWANG, Chae Dong LEE
