Multilayer chip capacitor

Abstract

A multilayer chip capacitor, which reduces ESL generated due to current flowing through external electrodes and assures an improved mechanical strength. The multilayer chip capacitor includes an upper dummy layer and a lower dummy layer; a plurality of internal electrodes interposed between the upper and lower dummy layers; and external electrodes connected to the internal electrodes, wherein the thickness of the lower dummy layer is smaller than the thickness of the upper dummy layer.

Description

[0001] related application [0002] This application claims priority from Korean Application No. 2005-5513 filed on January 20, 2005 and Korean Application No. 2004-16874 filed on February 28, 2005, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to a multilayer chip capacitor, and more particularly, to a multilayer chip capacitor having low equivalent series inductance (ESL) in high frequency circuits. Background technique [0004] In general, a multilayer chip capacitor has a small size, realizes a high capacitance, and is easy to mount on a substrate, and thus is widely used in various electronic devices. Multilayer chip capacitors are used as capacitive elements in high-frequency circuits, especially as decoupling capacitors arranged in power supply circuits of LSIs. In order to use a multilayer chip capacitor in a high frequency circuit, the multilayer chip capacitor must have a low ESL value. W...
