Countermeasure Against Harmonic Noise in Power Line Using 3-Terminal Feed-Through Filters
A capacitor is the most basic electronic component for noise suppression in power lines of electronic equipment. A capacitor has a characteristic that, the higher the frequency, the easier the current passes through it, and when a power line is connected to the ground through a capacitor, high-frequency noise is bypassed to the ground and separated.
