Capacitor mounting structure, capacitor - mounted board, and wiring board for use in capacitor mounting

摘要

A capacitor mounting structure has four capacitors close-arranged so that the outline of the arrangement is almost rectangular. The capacitors are arranged so that an angle formed by the current vectors of each pair of adjacent capacitors is 90 degrees and that one end face in the length direction of each capacitor is directed in parallel to an inner side face of another adjacent capacitor.
