Abstract
A multilayer electronic component includes a ceramic body having stacked dielectric layers to form a first capacitor part and a second capacitor part, wherein the first capacitor has a constant capacitance, and the second capacitor part has a variable capacitance; a voltage control terminal formed on a lateral surface of the ceramic body; an input terminal disposed on another lateral surface of the ceramic body corresponding to the first capacitor part; and an output terminal disposed on the other lateral surface of the ceramic body corresponding to the second capacitor part separate from the input terminal.
