Abstract

The present invention provides a multi-layer ceramic capacitor comprising: a main body including a dielectric layer and first and second internal electrodes point-symmetrical to each other, and provided such that the corresponding dielectric layer is interposed between the first and second internal electrodes; first and second connection electrodes passing through the body in a direction perpendicular to the dielectric layer and connected to the first internal electrode; a third connection electrode and a fourth connection electrode passing through the body in a direction perpendicular to thedielectric layer and connected to the second internal electrode; first and second external electrodes provided on both outer surfaces of the main body and connected to the first and second connectionelectrodes; and third and fourth external electrodes spaced apart from the first and second external electrodes and connected to the third and fourth connection electrodes. Each of the first and second internal electrodes includes an electrode non-formation region.

Description

[0001] This application claims Korean Patent Application No. 10-2019-0081138 filed with the Korean Intellectual Property Office on July 5, 2019 and Korean Patent Application No. 10-2019-0080682 filed with the Korean Intellectual Property Office on July 4, 2019 The disclosure of this Korean patent application is hereby incorporated by reference in its entirety for the benefit of priority of the patent application. technical field [0002] The present disclosure relates to a multilayer ceramic capacitor. Background technique [0003] Recently, the use of electronic devices using multilayer ceramic capacitors (MLCCs) has rapidly increased. In particular, with the advent of the fifth generation (5G) communication era, smartphones require a larger number of capacitors and higher capacitance capacitors. On the other hand, since the mounting area of ​​passive components such as MLCCs and inductors has been reduced due to the miniaturization technology of group products, miniaturiz...
