Abstract
A multilayer ceramic capacitor may include: a ceramic body; a first internal electrode is spaced apart from first and second end surfaces by a predetermined distance and includes first and second lead portions which are spaced apart from each other and exposed to a first main surface; and a second internal electrode is spaced apart from the first and second end surfaces by a predetermined distance and includes a third lead portion positioned between the first and second lead portions and exposed to the first main surface. The ceramic body may further include first and second dummy electrodes, a first dummy electrode being disposed on a dielectric layer on which the first internal electrode is disposed, and a second dummy electrode being disposed on a dielectric layer on which the second internal electrode is disposed.
Description
[0001] Cross References to Related Applications [0002] This application claims the benefit of Korean Patent Application No. 10-2014-0064328 filed with the Korean Intellectual Property Office on May 28, 2014, the contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to a multilayer ceramic capacitor and a board on which the multilayer ceramic capacitor is mounted. Background technique [0004] When the equivalent series inductance (ESL) in multilayer ceramic capacitors increases, the performance of electronic products degrades. In addition, due to the increasing miniaturization of high-capacitance electronic devices, the degree of degradation of electronic product performance increases relatively with the increase of ESL. [0005] Multilayer ceramic capacitors are effectively used as decoupling capacitors in high-frequency circuits such as power supply circuits in large-scale integration (LSI) systems, and the like. ...
