    摘要： A projection 23 is formed on a connecting terminal part 22 opposing to a side surface 16 of a ceramic electronic component main body 12 in a terminal member 19 by processing the metal plate which provides this terminal member 19. This projection 23 is made to project toward the side surface 16 of the ceramic electronic component main body 12. The interval more than the predetermined dimension is reliably formed between the connecting terminal part 22 and the side surface 16 of the ceramic electronic component main body 12 by the projection 23. This prevents the solder from reaching even to the ceramic electronic component main body 12.

    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： 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 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.
