By controlling shapes of internal electrodes, when short-circuit occurs between the internal electrodes, a short-circuited portion may be opened by an overcurrent, to serve as a fuse. Also, by controlling shapes of internal electrodes, equivalent series inductance (ESL) at a high frequency may be reduced.

Multilayer electronic component

A multilayer electronic component includes a body including a first internal electrode and a second internal electrode alternately disposed in a first direction with a dielectric layer interposed therebetween, and including a first surface and a second surface opposing each other in the first direction, a third surface and a fourth surface opposing each other in a second direction, and a fifth surface and a sixth surface opposing each other in a third direction. A first external electrode is disposed on the third, fourth, fifth, and sixth surfaces. A second external electrode is disposed on one or more of the first and second surfaces, and a via electrode is exposed through a surface on which the second external electrode is disposed. A ratio W/L is 0.95 or more and 1.05 or less, where L is a length of the body and W is a width of the body.

A composite electronic component includes a capacitor structure including a dielectric layer, and a first internal electrode and a second internal electrode alternately arranged in a first direction, with the dielectric layer interposed therebetween; a fuse structure including a fuse and a fuse body; a common electrode disposed between one surface of the capacitor structure in a second direction, crossing the first direction, and one surface of the fuse structure in the second direction, and connected to the first internal electrode and the fuse; a first external electrode disposed on the other surface of the fuse structure in the second direction, and connected to the fuse; and a second external electrode disposed on the other surface of the capacitor structure in the second direction, and connected to the second internal electrode.
