<p>PURPOSE:To provide an effective countermeasure for electromagnetic trouble by improving the frequency characteristics of a capacitor circuit. CONSTITUTION:A notched part A, having the width narrower than the size of the electrode of a chip capacitor C, is provided on a part of a wiring pattern, one side of the electrode of the capacitor is connected to the notched part A, and other side of the electrode is connected to the wiring pattern on the side of a GND. As a result, the current which flows by-passing the capacitor C can be cut, frequency characteristics can be improved, and the effective countermeasure for electromagnetic trouble can be obtained. Also, the same effect can be obtained by providing a cut-off part on the wiring pattern and by lap- jointing the electrode of the capacitor to the cut-off part. Besides, the same effect can be obtained by connecting the electrodes of the capacitor to both ends of the cut-off part and also by connecting the upper side of the electrodes of the capacitor using a short bar and the like.</p> |
