Abstract
A multilayer thin-film capacitor includes a first multilayer body and a second multilayer body spaced apart from each other in a vertical direction by a split layer. The second multilayer body is disposed on a lower surface of the first multilayer body, the first multilayer body constitutes a top capacitor, and the second body constitutes a bottom capacitor. First, second, and third external terminals may be disposed on an upper surface of the first multilayer body and be connected to internal electrode layers of the first and second multilayer bodies.
