transfer function, the LC filter has each frequency called “pole” and “zero point” as shown in the equations below. The zero point depends on the ESR of the capacitor. Since polymer capacitors have low ESR, using them as input and output smoothing capacitors can downsize power supply units.
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 .
Because capacitors are reactive elements, they can be used in analog electronic filters. The reason for this is that, as mentioned in the article about impedance and reactance, a capacitor's impedance is a function of frequency. This means that a capacitor's effect on a signal is frequency-dependent, which is a useful trait in filter construction.
We use a capacitor to filter out the DC signal. We do this by placing the capacitor in series. In this configuration, which is the circuit you see below, this is a capacitive high-pass filter. Low frequency, or DC, signals will be blocked.
In the switching power supply, the filter capacitor is extremely critical. The correct selection of filter capacitors, particularly the output filter capacitor, is a subject that all engineering and technical staff are worried about.

In the power rectifier circuit, the filter capacitor is utilized to filter out AC components and make the output DC smoother. To improve the operating effect of the filter capacitor in precision circuits, a combination of parallel capacitor circuits is frequently utilized at this time.
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.
