What is a filter capacitor?

A filter capacitor is a capacitor which filters out a certain frequency or range of frequencies from a circuit. Usually capacitors filter out very low frequency signals. These are signals that are very close to 0Hz in frequency value. These are also referred to as DC signals. How filter capacitors work is based on the principle of .

How does a capacitor filter a DC signal?

How does a capacitor work?

And this capacitor filters out the DC component so that only AC goes through. In the same way that capacitors can act as high-pass filters, to pass high frequencies and block DC, they can act as low-pass filters, to pass DC signals and block AC. Instead of placing the capacitor in series with the component, the capacitor will be placed in parallel.

What is a Y capacitor?

Y capacitors are often found in the input and output filters of these power supplies to minimize the noise conducted through the lines.
