Problems solved by technology

As a result, not only current fluctuations occur, but also the ESL hinders the charge and discharge of the multilayer capacitor, so the voltage fluctuation of the power supply tends to increase, making it unsuitable for the future increase in CPU speed.

Embodiment Construction

[0041] The multi-terminal type multilayer capacitor 10 as the multilayer capacitor of the first embodiment of the present invention is shown in FIGS. 1 to Figure 6 Shown. As shown in these figures, a rectangular parallelepiped laminated body that is a dielectric substrate 12 is used as the main body to constitute the multi-terminal type laminated capacitor 10 of this embodiment, wherein the rectangular parallelepiped laminated body is formed by stacking a plurality of laminated dielectric sheets, namely ceramics. The green sheet is obtained by sintering (in the text, "inside" refers to the side away from the top view, and "outside" refers to the side in front of the eye when viewed from the top).

[0042] in Figure 4 At a predetermined height position in the dielectric substrate 12 shown, a planar internal electrode 21 is arranged, and the internal electrode 22 has a lead portion 21A drawn from the innermost part of the internal electrode 22 on the left end in FIG. 1. In additio...

Abstract

A multilayer capacitor includes: a dielectric element; a pair of first internal conductors with same polarity disposed in the dielectric element to be adjacent to each other while being separated from each other by the dielectric layer; first leadout portions led out from the pair of first internal conductors respectively, one being provided for each of the first internal conductors; a pair of second internal conductors with same polarity disposed in the dielectric element to be adjacent to each other while being separated from each other by the dielectric layer; and second leadout portions led out from the pair of second internal conductors respectively, one being provided for each of the second internal conductors, wherein the first leadout portion and the second leadout portion led out respectively from the first internal conductor and the second internal conductor disposed adjacent to each other are led out to substantially the same positions in side faces facing each other of the dielectric element, respectively. Therefore, a multilayer capacitor capable of reducing equivalent series inductance to reduce voltage fluctuation of a power source of a CPU is obtained.

Description

Technical field [0001] The present invention relates to a multilayer capacitor with a reduced equivalent series inductance (ESL), and more particularly to a multilayer ceramic chip capacitor of a multi-terminal type capable of reducing the voltage fluctuation of a power supply for a CPU. Background technique [0002] In recent years, the CPU (main arithmetic processing device) used in the information processing device has increased its operating frequency and significantly increased its current consumption due to the increase in processing speed and high integration. Furthermore, in accordance with the aforementioned facts, there is a tendency for the operating voltage to decrease due to the decrease in power consumption. Therefore, in the power supply for supplying power to the CPU, a larger current fluctuation is generated at a faster rate, and it becomes very difficult to control the voltage fluctuation caused by the current fluctuation within the allowable value of the power ...
