Abstract
A multilayer capacitor includes a capacitor body including dielectric layers and internal electrodes alternately disposed with the dielectric layers interposed therebetween; and an external electrode disposed on the capacitor body to be connected to one or more of the internal electrodes. Porosity of ends of the internal electrodes is less than 50% on an interfacial surface between a margin of the capacitor body in a width direction the capacitor body and the internal electrodes.
Claims9
A multilayer capacitor, comprising:
- a capacitor body including dielectric layers and internal electrodes alternately disposed with the dielectric layers interposed therebetween;
- and
- an external electrode disposed on the capacitor body to be connected to one or more of the internal electrodes,
- wherein porosity of ends of the internal electrodes is 24% or more and less than 50% on an interfacial surface between a margin of the capacitor body in a width direction of the capacitor body and the internal electrodes.
A board on which a multilayer capacitor is mounted, the board comprising:
- a board having electrode pads on one surface of the board;
- and
- a multilayer capacitor having an external electrode connected to one of the electrode pads,
- wherein the multilayer capacitor includes a capacitor body including dielectric layers and internal electrodes alternately disposed with the dielectric layers interposed therebetween;
- and the external electrode disposed on the capacitor body to be connected to one or more of the internal electrodes, and porosity of ends of the internal electrodes is 24% or more and less than 50% on an interfacial surface between a margin of the capacitor body in a width direction of the capacitor body and the internal electrodes.
A multilayer capacitor, comprising:
- a capacitor body including dielectric layers and internal electrodes alternately disposed with the dielectric layers interposed therebetween, the capacitor body including first and second surfaces opposing each other in a thickness direction of the capacitor body, third and fourth surfaces opposing each other in a length direction of the capacitor body, and fifth and sixth surfaces opposing each other in a width of the capacitor body, and the internal electrodes including first internal electrodes extending from the first surface and the second internal electrodes extending from the second surface;
- and
- first and second external electrodes disposed on the third surface and the fourth surface to be connected to the first internal electrodes and the second internal electrodes, respectively,
- wherein in a width direction-thickness direction plane, a ratio of the number of internal electrodes each having a pore at an end thereof located at a side of one the fifth and sixth surfaces to the number of the internal electrodes is greater than 0 and less than 50%.
