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 isrepresented 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 is a divisional application of an invention patent application with an application date of August 1, 2016, an application number of 201610620295.1, and an invention title of "dielectric composition and a multilayer ceramic capacitor comprising the same". 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 ...
