The value of the coupling capacitor depends on the frequency of the AC signal being passed through. Capacitors are reactive devices, meaning they offer different impedance (or resistance) to signals of different frequencies. To low-frequency signals, such as DC with a frequency of 0Hz, capacitors offer very high resistance.
Coupling capacitors are used in electronic circuits to pass the desired AC signal and block unwanted DC components. These unwanted DC signals come from electronic devices or preceding stages of an electronic circuit. In audio systems, DC components affect the quality of the desired signal by introducing noise.
Coupling capacitors allow AC components to pass while blocking DC components. Decoupling capacitors are used in electronic circuits as energy reservoirs to prevent quick voltage changes. Bypassing capacitors clean DC signals by shunting unwanted AC components to ground.
About High-Frequency Capacitors High-frequency capacitors are marketed as such due to their ability to retain ideal capacitive behavior up to very high frequencies. Capacitors will not exhibit ideal behavior up to the intended operating frequencies in RF systems, even if they are marketed as “high-frequency” or “RF” components.
In coupling applications, a capacitor blocks low frequency DC signals and allows high frequency AC signals to pass. To low frequency components, such as the DC signals, a capacitor exhibits high impedance, thereby blocking them. On the other hand, a capacitor exhibits low impedance to high frequency components.
