Abstract
A composite electronic component may include: an input terminal receiving power which has been converted by a power management unit; a power smoothing unit including a capacitor including a ceramic body in which a plurality of dielectric layers and internal electrodes are stacked such that the internal electrodes are disposed to face each other with the dielectric layer interposed therebetween and an inductor including a magnetic body including a coil part and a magnet, and smoothing power; and an output terminal supplying the smoothed power. The inductor may suppress an alternating current (AC) component of supplied power and the capacitor may reduce ripples in the supplied power.
