摘要： A multilayer capacitor includes first and second internal electrodes that are opposed to each other so as to generate an electrostatic capacitance and have a capacitance generating portion functioning to generate the electrostatic capacitance, terminal connecting portions connected to corresponding external terminal electrodes, and extended portions connecting the capacitance generating portion to the terminal connecting portions. The extended portions are narrower than the capacitance generating portion and the terminal connecting portion and are curved in the direction of their thickness so as to provide a longer effective length. The multi-terminal capacitor is capable of increasing an ESR without adding a separate additional element.

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 ESL, 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. Furthermore, a combined ESR of the first capacitor portions is set to be less than or greater than a combined ESR of the second capacitor portion.

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.
