Problems solved by technology

[0004] However, BLCCs are limited by the fact that the external electrodes are only formed on the mounting surface of the hexahedral body.
In particular, since the capacitor should be loaded only in the direction of the mounting surface on which the external electrodes are formed, the workability of the product and the convenience of use by consumers may be reduced.
In addition, compared with the MLCC according to the prior art, the soldering area is reduced so that the bonding strength between the capacitor and the circuit board on which the capacitor is mounted can be weakened

The first auxiliary external electrode and the second auxiliary external electrode are electrically connected to the first external electrode and the second external electrode, respectively, and cover a part of the surface of the main body connected to the one surface of the main body.

Description

[0001] This application claims priority to Korean Patent Application No. 10-2015-0151068 filed on October 29, 2015 at the Korean Intellectual Property Office and No. 10-2016-0021731 filed on February 24, 2016 at the Korean Intellectual Property Office rights, the disclosure of said Korean Patent Application is hereby incorporated by reference in its entirety. technical field [0002] The present disclosure relates to a capacitor and a method of manufacturing the capacitor. Background technique [0003] According to improvement in performance of miniaturized information technology (IT) products, demand for products having a small size while providing ultra-high capacitance has increased. Therefore, among existing multilayer ceramic capacitors (MLCCs), a bottom land ceramic capacitor (BLCC) in which external electrodes are formed on a mounting surface has been studied as a new type of capacitor. The external electrodes are formed on the mounting surface so that the area of ​​...
