Abstract:
1. A multilayer capacitor comprising: a capacitor body having a layered structure including a plurality of laminated dielectric layers; wherein the capacitor body includes first and second capacitor portions; the first capacitor portion includes at least one pair of first and second internal electrodes opposing each other with a predetermined one of the dielectric layers interposed therebetween to define a capacitance; the second capacitor portion includes at least one pair of third and fourth internal electrodes opposing each other with a predetermined one of the dielectric layers interposed therebetween to define a capacitance; a resonant frequency of the first capacitor portion is greater than a resonant frequency of the second capacitor portion; an equivalent series resistance per layer provided by one pair of the third and fourth internal electrodes and an intervening one of the dielectric layers included in the second capacitor portion is greater than an equivalent series resistance per layer provided by one pair of the first and second internal electrodes and an intervening one of the dielectric layers included in the first capacitor portion; and a combined equivalent series resistance provided by all of the first and second internal electrodes and the intervening dielectric layers included in the first capacitor portion is substantially equal to a combined equivalent series resistance provided by all of the third and fourth internal electrodes and the intervening dielectric layers included in the second capacitor portion.
