SRF & PRF for RF Capacitors — Johanson Technology
At the PRF, the transmission impedance goes relatively high, and the capacitor is virtually useless around this frequency. There is an industry "trick" to effectively extend the usable frequency range in this application. That is to mount the capacitor in a vertical position so that the capacitor terminations both still meet the pads where it''s mounted, and so the width of …

Capacitor''s self-resonance
The self-resonance of a capacitor imposes the frequency limit where it acts as a true capacitive reactance to the circuit.

If the tuning circuit has a high Q, it will have a small bandwidth, so signals from other stations at frequencies even slightly different from the resonant frequency encounter a high impedance and are not passed by the circuit. Cell phones work in a similar fashion, communicating with signals of around 1 GHz that are tuned by an inductor-capacitor circuit. One of the most common …
