Embodiment Construction

[0014] Hereinafter, embodiments of the inventive concept will be described as follows with reference to the accompanying drawings.

[0015] However, inventive concepts 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.

[0016] Throughout the specification, it will be understood that when an element such as a layer, region or wafer (substrate) is referred to as being "on", "connected to" or "bonded to" another element When an element is referred to as an element, it may be directly "on," "connected to," or "coupled to" another element or other elements may be present 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 inte...

Abstract

A dielectric composition and a multilayer ceramic capacitor containing the same are provided. The dielectric composition contains an oxide of Ba and Ti as a main ingredient, and the main ingredient is represented by (Ba1-x)(Na, Ca)x)TiO3, wherein 0.005<=x<=0.035 and 0.994<(Ba1-x(Na, Ca)x) / Ti<1.003.

Description

[0001] This application claims the benefit of priority of Korean Patent Application No. 10-2015-0187166 filed on December 28, 2015 in the Korean Intellectual Property Office, the entire disclosure of which is hereby incorporated by reference. technical field [0002] The present disclosure relates to a new dielectric composition capable of satisfying X5R temperature characteristics, X7R temperature characteristics, and X8R temperature characteristics to improve reliability and a multilayer ceramic capacitor including the same. Background technique [0003] Recently, due to an increase in the size of a display device, an increase in the speed of a central processing unit (CPU) of a computer, etc., heat generation has become a significant problem in electronic devices. Therefore, X5R (operating temperature: -55°C-+85°C) multilayer ceramic capacitors, X7R (operating temperature: -55°C-+ 125°C) multilayer ceramic capacitors and X8R (operating temperature: -55°C to +150°C) multil...
