Can a capacitor be used to target multiple frequencies?

You can of course use multiple values to target multiple frequencies by placing a capacitor in parallel with other ones. You will see these all of the time near the supply voltage pins of chips. Usually a value of 0.1 uF can be found, or the datasheet of the chip will specify the ideal value.

What are the frequency characteristics of a capacitor?

Frequency characteristics of an ideal capacitor In actual capacitors (Fig. 3), however, there is some resistance (ESR) from loss due to dielectric substances, electrodes or other components in addition to the capacity component C and some parasitic inductance (ESL) due to electrodes, leads and other components.

What are the frequency characteristics of capacitor impedance?

In the capacitive characteristic region, the larger the capacitance, the lower is the impedance. Moreover, the smaller the capacitance, the higher is the resonance frequency, and the lower is the impedance in the inductive characteristic region. Our explanation of the frequency characteristics of capacitor impedance may be summarized as follows.

How many uF capacitor should I use?

In the power supply of Audio circuits, it is better to use a 2200 uF or 4700 uF capacitor since the ripples may create hum in the circuit. Leakage current is another problem in capacitors. Some of the charges will leak, even if the capacitor is charging.
