Abstract

A multilayer chip capacitor includes a capacitor body including a first capacitor part and a second capacitor part, first and second external electrodes respectively formed on first and second longer side faces of the capacitor body, and third and fourth external electrodes respectively formed on first and second shorter side faces of the capacitor body. The first capacitor part includes first and second internal electrodes of opposite polarity, and the second capacitor part includes third and fourth internal electrodes of opposite polarity. The first to fourth internal electrodes each have one lead. The first to fourth external electrodes are respectively connected to the leads of the first to fourth internal electrodes. A series resonance frequency of the first capacitor part is different from that of the second capacitor part. Equivalent series resistance (ESR1) of the first capacitor part and the equivalent series resistance (ESR2) of the second capacitor part satisfy ERS1≧20 mΩ and 0.7(ESR1)≦ESR2≦1.3(ESR1).
