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.
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.
1. Frequency characteristics of capacitors The impedance Z of an ideal capacitor (Fig. 1) is shown by formula (1), where ω is the angular frequency and C is the electrostatic capacitance of the capacitor.
Capacitors get the most attention because of their high-frequency characteristics in determining PDN impedance, as well as their use in RF filter circuits. However, parasitics in the pad and trace placement for these components always modify the component rating.
While pouring over texts with explanations of various aspects is one approach to overcoming this hurdle, such texts rarely include an explanation of the high-frequency characteristics of inductors and capacitors, which are basic electric circuit elements.
In addition to the actual capacitance value, there is a short list of specifications to look at when selecting capacitors for high-frequency systems. Case size: Smaller case sizes tend to have higher self-resonance, and they can access smaller capacitance values (see below).
