What is a high frequency capacitor?
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.
Which high-frequency ceramic capacitor is best for high power RF design?

What type of capacitors have a high stability?
These capacitors are usually ceramics, and some ceramic dielectrics like NP0/C0G have very high stability. Self-resonant frequency or ESL: These values might be specified on a design curve or provided directly in the datasheet. They could also be determined from an impedance curve.
Why are high-stability capacitors important in high-speed RF applications?
While high-stability capacitors are valuable in many instances, they shine in high-speed RF applications. As capacitors tend to leak more energy at high frequencies, preventing loss to the environment is energy efficient and prevents heat-related aging of components and the substrate. Capacitors fill a wide variety of roles across a circuit.

1.2: Passive components at high frequency
At low frequency, the inductor behaviour dominates as it has the lowest reactance, while at high frequency, the capacitor dominates. Thus, an inductor will show capacitive behavior at high frequencies. Figure (PageIndex{7}): A non-ideal inductor has both a capacitive and a resistive component. Note that for an ideal inductor (R_s = 0 ...

Lecture 8
Remember that the impedance of a capacitor is inversely proportional to frequency. Therefore at low frequency, a capacitor appears as open-circuit. At high frequency, it appears as short-circuit. Using the principle of voltage divider, this circuit will give you a low output at high frequency (XCis small), and does not

High Frequency Passive Components
Inductors and capacitors are often described in terms of the (1) inductance/capacitance at a particular frequency, (2) quality factor and (3) self-resonant frequency (SRF). The inductance/capacitance varies due to the non-ideal behavior of the component. For instance, the intrinsic inductance may vary with frequency due to non-uniform current

How do smaller capacitors filter out higher frequencies than …
If practical capacitors were purely capacitive, then indeed, a larger capacitor would do an even better (or at least "as good") job of filtering high frequencies as a smaller value one.. But capacitors are not purely capacitive; ones we can practically build are also unfortunately inductive, and at some frequency the inductive behavior dominates over the capacitive one, …
