  • Publication number: 20190279824
    Abstract: A multilayer capacitor in which acoustic noise is reduced has an area of overlap between internal electrodes in an active region of a lower portion of a capacitor body that is smaller than an area of overlap between internal electrodes in an active region of an upper portion of the capacitor body. The multilayer capacitor can be bonded to a board by relatively small solders such that the lower portion is adjacent the board. Deviations between areas of overlap of adjacent internal electrodes in the upper and lower portions of the active region are minimized to reduce piezoelectric deformation of the capacitor body.
