Best Capacitors For Audio: Types, Sizing, And Selection
For high-frequency signals (e.g., high-speed audio processing), look for capacitors with a low inductance (the tendency to store energy in a magnetic field). Another important consideration is the capacitance value. A general rule of thumb is to use capacitors with a value around 1-10 uF for decoupling audio signals. However, this can vary depending on the

How to Select High-Frequency Capacitors for RF Circuits
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).
How to choose the right capacitor for any application
Bypassing capacitor selection depends on your requirement specifications. Low-frequency applications can be served by (EMI) and high-frequency radio frequency interference (RFI). Should these capacitors fail, they are designed to fail in a safe mode, meaning their failure will not lead to personal injury nor equipment damage. Safety capacitors are also called

6 FAQs about [High Frequency Capacitor Selection]
How to choose a capacitor for high speed digital signalling?
With high speed digital signalling, capacitors should be selected such that they have ideal capacitive impedance up to the signal’s knee frequency (0.35 divided by the 10%-90% rise time). In other words, the self-resonant frequency should be greater than the knee frequency.
How to choose a capacitor for high frequency analog signals?
In other words, the self-resonant frequency should be greater than the knee frequency. With high frequency analog signals, any capacitors should be chosen such that the relevant frequencies in the system are lower than the self-resonant frequency.
What is the lowest rated frequency for a high frequency capacitor?
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:
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.
What happens if a capacitor reaches a high frequency?
At low frequency, the impedance provided by the capacitor is dominant, and your capacitor will exhibit close to ideal behavior. At sufficiently high frequency, the ESL value takes over, and the impedance starts to appear inductive. This produces an effect known as self-resonance at just the right frequency.
What is equivalent high frequency capacitor model?
Equivalent high frequency capacitor model. This means that the important characteristic distinguishing different capacitors for different frequency ranges is the capacitor’s self-resonant frequency. At this particular frequency, the capacitor will exhibit its minimum impedance and a very strong current response.
