AI Customer ServiceAbout 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.
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.
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).
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.
At higher frequencies, reactance is smaller, so the capacitor charges and discharges rapidly. In DC circuits, capacitors block current due to infinite reactance. But in AC circuits, capacitors pass current easily at high enough frequencies. The voltage and current are out of phase in an AC capacitance circuit.
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.
