  • Publication number: 20250218689
    Abstract: 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.

  • Publication number: 20250104923
    Abstract: A multilayer electronic component includes a body including a dielectric layer and an internal electrode disposed on the dielectric layer, an external electrode including a base electrode layer connected to the internal electrode, and an interface layer disposed between an end of the dielectric layer and the base electrode layer. The interface layer includes a first glass containing Ba, Zn, and Si. The base electrode layer includes a second glass containing Ba and Si. When an average molar ratio (Ba/Si) of Ba to Si contained in the first glass is M1 and an average molar ratio (Ba/Si) of Ba to Si contained in the second glass is M2, M1 and M2 satisfy M1/M2?1.5.
