Abstract
A three-terminal multilayer ceramic capacitor includes a capacitor including a ceramic layer, first and second internal electrodes, first and second end surface electrodes, and first and second side surface electrodes, and has a lengthwise dimension of about 1300 μm or more and about 1500 μm or less, a widthwise dimension of about 1000 μm or more and about 1200 μm or less, a heightwise dimension of about 570 μm or more and about 680 μm or less, and a capacitance of about 12 μF or more and about 32 μF or less. The first and second end surface electrodes, and the first and second side surface electrodes include a Ni underlying electrode layer and at least one plating electrode layer. The first and second end surface electrodes have a thickness of about 0.73% or more and about 3.00% or less relative to the lengthwise dimension.
