The GQM/GJM high-frequency ceramic capacitors are the best choice for high performance and high power RF designs requiring voltages up to 500V DC. These capacitors offer EIA sizes 0201, 0402, 0603, 0805, and the 1111 size with a capacitance range of 0.1pF to 100pF.
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.
These Murata High-Frequency Ceramic Capacitors feature low power consumption for mobile telecommunications, the GQM and GJM capacitors come with copper electrodes that allow for ultra-low ESR, high Q in the GHz frequencies, and high RF current handling capability.
First series resonance (FSR) and first parallel resonance (FPR): These are the lowest rated frequency value at which S11 and S21 are rated for the capacitor in question. Here are two excellent sets of high frequency capacitors that are ideal for applications in the GHz range:
KEMET’s HiQ CBR RF Capacitor Series features a copper electrode BME (Base Metal Electrode) system that offers ultra-low ESR and High Q in the VHF, UHF, and microwave frequency bands. Low ESR allows for higher RF currents which are ideal for various applications.
If you need discrete capacitors in a very high frequency board, then you need to account for these values in your circuit model. These values are determined by the following factors: The result is that the above curve is not necessarily observed once the components are placed on a real PCB.

Why does an inductor behave as a capacitor at high frequencies?
As the frequency increases, the impedance of the inductor increases while the impedance of the parasitic capacitor decreases, so at some high frequency the impedance of the capacitor is much lower than the impedance of the inductor, which means that your inductor behaves like a capacitor. The inductor also has its own resonance frequency.
