  • Publication number: 20090201627
    Abstract: A multilayer capacitor array achieves a high ESR because terminal conductors to which internal electrodes in capacitance sections are connected in parallel are connected in series through internal electrodes in ESR control sections to external electrodes. Since in the multilayer capacitor array the internal electrodes extend as far as a boundary between capacitor element portions, electrostriction occurs in an entire laminate including a region near the boundary between the capacitor element portions, with application of a voltage from the outside. Therefore, concentration of stress due to electrostriction is avoided, so as to suppress occurrence of cracking or the like.

    Abstract: Methodologies and structures are disclosed for providing multilayer electronic devices having low inductance and high ratings, such as for capacitor devices for uses involving faster pulsing and higher currents. Plural layer devices are constructed for relatively lowered inductance by relatively altering typical orientation of capacitors such that their electrodes are placed into a vertical position relative to an associated circuit board. Optionally, individual leads may be formed so that the resulting structure can be used as an array. Internal electrodes may be arranged for reducing current loops for associated circuits on a circuit board, to correspondingly reduce the associated inductance of the circuit board mounted device. Leads associated with such devices may have added tab-like structures which serve to more precisely place the lead, to improve the lead to capacitor strength, and to promote lower resistance and inductance.

    Abstract: 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.

  • Patent number: 7492570
    Abstract: Systems and methods for reducing switching noise in an integrated circuit. In one embodiment, decoupling capacitors are connected to the integrated circuit from the underside of the substrate on which the integrated circuit die is manufactured. The decoupling capacitors are positioned with a higher concentration in the “hot spot” areas of the integrated circuit instead of being evenly distributed. In one embodiment, the decoupling capacitors and the corresponding hole(s) in a circuit board on which the integrated circuit is mounted are positioned so that the circuit board provides support for the central portion of the integrated circuit and thereby prevents the integrated circuit from flexing away from the heat sink/spreader. In one embodiment, the concentration of vias connecting the different ground planes and/or power planes within the integrated circuit is higher in hot spots than in other areas.
