Problems solved by technology

When a short circuit occurs in an MLCC or a high voltage is applied to an MLCC, the electric field concentrates on the vulnerable parts of the multiple dielectric layers, resulting in a High Voltage Stress (HVS) failure in which burn marks remain

Embodiment Construction

[0026] Hereinafter, embodiments of the present disclosure will be described below with reference to the accompanying drawings.

[0027] However, this disclosure 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.

[0028] Throughout the specification, it will be understood that when an element such as a layer, region or substrate is referred to as being "on," "connected to," or "coupled to" another element , it may be directly "on" another element, "connected to" or "coupled to" another element, or there may be other elements intervening therebetween. In contrast, when an element is referred to as being “directly on,” “directly connected to” or “directly coupled to” another element, there may be no intervening elements or layers prese...

Abstract

The invention discloses a multi-layered ceramic capacitor and a board for mounting the same. The multi-layered ceramic capacitor comprises a main body and a first external electrode, a second external electrode and a third external electrode, wherein, a main body is formed by stacking multiple dielectric layers and multiple first internal electrodes and multiple second electrodes in the width direction of the main body; each of the first internal electrodes and the second electrodes comprises an outtake exposed from an installation surface of the main body separately, wherein, the first external electrode to the third external electrode are arranged on the installation surface of the main body to be connected to each outtake; and a step compensation pattern is formed on the part of the outtake of the main body and is exposed from the installation surface of the main body.

Description

[0001] This application claims the benefit of priority from Korean Patent Application No. 10-2015-0180343 filed in the Korean Intellectual Property Office on December 16, 2015, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0002] The present disclosure relates to a multilayer ceramic capacitor (MLCC) and a board for mounting the multilayer ceramic capacitor. Background technique [0003] MLCCs have advantages such as relatively small size, high capacitance, and easy mounting. [0004] Such MLCCs can be mounted on circuit boards of various electronic products such as image display devices including liquid crystal displays (LCDs) and plasma display panels (PDPs), computers, smartphones, and mobile phones to charge and discharge the MLCCs . [0005] Such an MLCC includes a body portion in which a plurality of dielectric layers and internal electrodes are laminated. Here, a stepped portion may be generated at an edge portion of ...
