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 .
A capacitor is used to filter out the DC signal. This can be done by connecting the capacitor in series in the circuit. The following circuit is the capacitive high-pass filter. In this, signals like DC or low frequency will be blocked.
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.
Generally, a capacitor filters out the signals which have a low frequency. The frequency value of these signals is near to 0Hz, these are also known as DC signals. So this capacitor is used to filter unwanted frequencies.
A filter circuit is a device that is used to remove the A.C components of the rectified output but allows the D.C components to reach the load. A filter circuit is in general a combination of inductor (L) and Capacitor (C) called an LC filter circuit. A capacitor allows A.C only and an inductor allows D.C only to pass.
A capacitor allows A.C only and an inductor allows D.C only to pass. So a suitable L and C network can effectively filter out the A.C component from the rectified wave. A filter circuit consists of passive circuit elements i.e., inductors, capacitors, resistors, and their combination.
