摘要： A bulk-acoustic wave resonator includes: a substrate; a lower electrode disposed on the substrate; a piezoelectric layer at least partially covering the lower electrode; and an upper electrode at least partially covering the piezoelectric layer. On a surface of the bulk-acoustic wave resonator, a centroid of an active area in which the lower electrode, the piezoelectric layer, and the upper electrode all overlap each other is aligned with a center of a rectangle defining an aspect ratio of the active area. The active area has a shape of a polygon symmetrical with respect to at least one axis passing through the center of the rectangle defining the aspect ratio. The aspect ratio is greater than or equal to 2 and less than or equal to 10.

摘要： A coil component includes a body and a coil portion disposed in the body and including first and second lead-out portions. Recesses are disposed along edges of one surface of the body, and expose the first and second lead-out portions to internal walls and lower surfaces of the recesses. First and second external electrodes are disposed in the recesses, and are connected to the first and second lead-out portions. A third external electrode is disposed in the recesses, and is connected to a connection electrode disposed on side surfaces of the body and on another surface of the body opposite to the one surface. An external insulating layer covers the connection electrode, and has an opening exposing at least a portion of the connection electrode. A shielding layers is disposed on the external insulating layer and in the opening and connects to the connection electrode.

摘要： A capacitor includes a plurality of cells each including a capacitance formation portion in which a plurality of trenches are positioned and a margin portion disposed around the capacitance formation portion. The cell includes three or more dielectric layers disposed in the capacitance formation portion and extending in the trenches, and three or more electrode layers sequentially stacked with dielectric layers interposed therebetween and extending in the trenches. At least first and second electrode layers have opposite polarities and each include a lead electrode extending from the capacitance formation portion to the margin portion. A lead electrode of the first electrode layer is disposed in a first region disposed to one side of a central portion of a cell, and a lead electrode of the second electrode layer is disposed in a second region disposed on another side of a central portion of the cell.
