Embodiment Construction

[0028] Hereinafter, embodiments of the present disclosure will be described as follows with reference to the accompanying drawings. This disclosure, however, may be embodied in many different forms and should not be construed as limited to the specific embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Therefore, the shapes and sizes of elements in the drawings may be exaggerated for clarity of description, and elements denoted by the same reference numerals are the same elements in the drawings.

[0029] Throughout the specification, unless otherwise explicitly stated, when a component is said to "comprise" or "comprise", it means that the component may also include other components, not exclude other components.

[0030] Hereinafter, when defining the direction of the capacitor body 110 to clearly illustrate the embodiments ...

Abstract

According to an embodiment of the present invention, provided is a multilayered ceramic capacitor. The multilayered ceramic capacitor includes: a body including a dielectric layer and first and secondinternal electrodes having different sizes, and including first and second sides facing each other in a layering direction of the first and second internal electrodes, third and fourth sides connected with the first and second sides and facing each other, and fifth and sixth sides connected with the first and second sides, connected with the third and fourth sides and facing each other; and firstand second external electrodes. When a longitudinal margin of the first internal electrode is defined as b and a transverse margin of the same is defined as d, and a longitudinal margin of the secondinternal electrode is defined as a and a transverse margin of the same is defined as c, the ratio (a / b) of the longitudinal margin (a) of the second internal electrode in contrast to the longitudinalmargin (b) of the first internal electrode is no less than 0.33 (but, a>0, b>0).

Description

[0001] This application claims the benefit of priority of Korean Patent Application No. 10-2019-0086398 filed with the Korean Intellectual Property Office on July 17, 2019, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0002] The present disclosure relates to a multilayer ceramic capacitor. Background technique [0003] A Multilayer Ceramic Capacitor MLCC is a passive component that controls electrical signals on a circuit. The main role of such multilayer ceramic capacitors is to accumulate charges in the electrodes, block direct current (DC) signals, and pass alternating current (AC) signals. That is, it can be seen that such multilayer ceramic capacitors play a role in stabilizing the operation of the IC by bypassing AC noise and removing it from the power line. [0004] When the electromagnetic distance of each layer is reduced, MLCC devices may have characteristic degradation due to a crosstalk phenomenon. [0005] In p...
