    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.

    摘要: In a capacitor body, a single second capacitor unit is interposed between two first capacitor units. The width direction dimension of each of extended portions of first and second internal electrodes included in the first capacitor unit is larger than the width direction dimension of each of extended portions of third and fourth internal electrodes included in the second capacitor unit. The area of each of the respective portions of a first opposed portion of the first internal electrode and a second opposed portion of the second internal electrode, the respective portions being opposed to each other, is smaller than the area of each of respective portions of opposed portions of the third and fourth internal electrodes, the respective portions being opposed to each other. Thus, a multilayer capacitor has a characteristic that is a combination of a low-ESL characteristic of the first capacitor unit and a high-ESR characteristic of the second capacitor.

    摘要: A multi-terminal monolithic ceramic capacitor arranged to reduce an equivalent series inductance and having an array structure is provided. A first same-polarity-connection conductor and a second same-polarity-connection conductor are provided inside a capacitor body so as to extend over at least two capacitors. The first same-polarity-connection conductor is electrically connected to a plurality of first external terminal electrodes, and the second same-polarity-connection conductor is connected to a plurality of second external terminal electrodes. In the monolithic ceramic capacitor which is mounted on a wiring substrate, the overall capacitance can be maintained even if an accident, such as cracking of a solder joint, occurs in one of the external terminal electrodes.

    摘要: A monolithic capacitor includes a main capacitor unit having first capacitor portions and a second capacitor portion arranged in a direction of lamination, with the first capacitor portion located towards at least one end in the direction of lamination, so that the first capacitor portion is located closer to a mounting surface than the second capacitor portion. The number of pairs of third and fourth lead-out portions for third and fourth internal electrodes in the second capacitor portion is less than the number of pairs of first and second lead-out portions for first and second internal electrodes in the first capacitor portion, so that the first capacitor portion contributes to decreasing ESL while the second capacitor portion contributes to increasing ESR.

    摘要: A layered capacitor includes a capacitor body that is divided into two first capacitor sections and a second capacitor section. The first capacitor sections are disposed at ends in a layer-stacking direction such that the second capacitor section is interposed between the first capacitor sections in the layer-stacking direction. The resonant frequency of the first capacitor sections is greater than that of the second capacitor section. The total number of third internal electrodes and fourth internal electrodes provided per dielectric layer included in the second capacitor section is less than the total number of first via conductors and second via conductors per dielectric layer included in the first capacitor sections. The ESR per dielectric layer included in the second capacitor section is greater than that per dielectric layer included in the first capacitor sections.
