Embodiment

[0111] Table 1 below shows changes in equivalent series resistance (ESR) according to changes in the aspect ratio (L / D) of the second conductor in the conductive resin layer of the multilayer ceramic capacitor.

[0114] It can be understood from the above table 1 that when the L / D is less than 1, the ESR is above 70Ω; however, when the L / D is above 1, the ESR is below 50Ω, which is significantly reduced.

[0115] Moreover, when L / D is 2 or more, ESR also falls significantly. Therefore, when the L / D is 2 or more, an ESR of 20mΩ or less is obtained.

[0116] As described above, according to exemplary embodiments of the present disclosure, there are provided a multilayer ceramic capacitor having reduced equivalent series resistance (ESR) when absorbing external impact and preventing ...

Abstract

There is provided a multilayer ceramic capacitor including: a ceramic body including dielectric layers and internal electrodes; electrode layers connected to the internal electrodes; and a conductive resin layer formed on the electrode layers and including a first conductor, a second conductor having a fiber shape, and a base resin. The multilayer ceramic capacitor provided by the invention may has reduced equivalent series resistance (ESR) when absorbing external impact and preventing permeation of an electroplate liquid.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2013-0109700 filed with the Korean Intellectual Property Office on September 12, 2013, the disclosure of which is hereby incorporated by reference into this application. technical field [0003] The present invention relates to a multilayer ceramic capacitor, a method of manufacturing the same, and a board for mounting the multilayer ceramic capacitor. Background technique [0004] Among ceramic electronic devices, a multilayer ceramic capacitor includes a plurality of stacked dielectric layers, internal electrodes arranged to face each other with a dielectric layer interposed therebetween, and external electrodes electrically connected to the internal electrodes. [0005] Multilayer ceramic capacitors have been widely used in mobile communication components, such as notebook computers, personal digital assistants (PDAs), mobile phones, etc., due to...
