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.

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： In a multilayer capacitor including a capacitor body, first capacitor portions and a second capacitor portion are arranged in the direction of lamination. While a resonant frequency of the first capacitor portions is set to be greater than a resonant frequency of the second capacitor portion so that the first capacitor portions contribute to low impedance, an ESR per layer of the second capacitor portion is set to be greater than an ESR per layer of the first capacitor portions so that the second capacitor portion contributes to high ESR. Further, a combined ESR of the first capacitor portions is set to be substantially equal to a combined ESR of the second capacitor portion.

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.
