6 FAQs about [Medium frequency DC filter capacitor]

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 .

Do capacitors filter a wide range of frequencies?

Pay attention to the SRF (as outlined in LvW's answer). This is true for caps, chokes, ferrites, etc. Because capacitors alone filter a wide range of frequencies. Graphs and effect for 1nF and 100nF are quiet close. (See answer below.) There isn't much difference in effect between 5 ohms and 0.1 ohms impedance as filtering is concerned.

Do ceramic capacitors filter better at higher frequencies?

If the capacitors were ideal, there would be no way that smaller value capacitors could filter better at higher frequencies. But every ceramic cap maintains a capacitor-like behavior up to some frequency. Then the parasitic inductance starts to assert itself and ultimately, at high frequencies, dominate the impedance characteristic.

What is a capacitive high-pass filter?

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. Usually, a 0.1µF ceramic capacitor, or value around that range, is placed after the signal that contains both DC and AC signals.

Can a capacitor be used as a low-pass filter?

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. The above is a high-frequency capacitive filter.

Why do we need a large capacitor for MMC?

The extensive use of sub-module (SM) capacitors causes heavier weight and higher cost, which hinders the further application of MMC. What is worse, the voltage fluctuation of the SM is in a reverse ratio with the operating frequency. Thus, a large capacitor is required to restrain the voltage ripple when operating at low frequencies.
