Multilayer capacitor having low equivalent series inductance and controlled equivalent series resistance |
摘要 |
In a capacitor body of a multilayer capacitor, one second capacitor portion is sandwiched between two first capacitor portions. An ESR is controlled by setting a width of lead portions of third and fourth internal electrodes disposed in the second capacitor portion to be less than that of lead portions of first and second internal electrodes disposed in the first capacitor portions and by changing ratios between the first and second capacitor portions in the width of the lead portions and in the number of stacked internal electrodes. In the first capacitor portions, current paths from the internal electrodes to an external terminal electrode are widely distributed so that the first capacitor portions have a relatively low ESL, and accordingly, the ESL of the entire multilayer capacitor is reduced. |
