LAMINATED CAPACITOR, WIRING BOARD, DECOUPLING CIRCUIT, AND HIGH-FREQUENCY CIRCUIT

摘要

PROBLEM TO BE SOLVED: To provide a preferable mounting structure for a laminated capacitor having low ESL, when it is used as a decoupling capacitor to be connected to a power circuit for an MPU chip of an MPU. SOLUTION: A laminated capacitor 41 is stored in a cavity 66 formd in a wiring board 62. The laminated capacitor 41 is provided with a plurality of first external terminal electrodes 49, connected to first inner electrodes 44 via a plurality of first through conductors 46 and a plurality of second external terminal electrodes 41 connected to second inner electrodes 45 via a plurality of second through-conductors 47. The first external terminal electrodes 49 are installed on a first principal plane 48 of the body 43 of the capacitor to be connected to hot-side via hole conductors 70 for a power supply inside the wiring board 62, and the second external terminal electrodes 51 are installed on a second principal plane 50, to be ground-connected directly to a mother board 67.
