摘要： In a band elimination filter, a plurality of capacitors are connected in parallel between first and second terminals of an electromagnetic noise source which generates voltage fluctuations in a connecting lead connected to the first terminal, with the capacitors being connected to the connecting lead at respectively corresponding branch points. For each capacitor, the total series inductance of a first circuit path is made less than that of a second circuit path, where the first circuit path extends from the corresponding branch point to the second terminal via the capacitor, and the second circuit path extends from that branch point to the first terminal of the electromagnetic noise source. A resistor is connected in series with at least one of the capacitors, for damping parallel resonance caused by inductance components of an adjacent pair of capacitors.
