X7R, X5R, C0G…: A Concise Guide to Ceramic Capacitor …

    Noisy Capacitors. If you design audio devices, or if you simply prefer quiet PCBs, you have another reason to choose C0G over X7R or X5R: Class 2 caps exhibit piezoelectric behavior that can cause them to function as both microphones (that will convert sound into electrical noise) and buzzers (that will convert AC signals into audible noise).

    Audio Capacitors - NP0/C0G or Film in Loud Enviornments. Ask Question Asked 1 year, 8 months ago. Active 1 year, 8 months ago. Viewed 697 times 3 \$\begingroup\$ I hear a lot of "audio-foolery" going around about capacitors and I have always steered clear of multiplayer ceramic caps because I was under the impression that they are microphonic. ...

BME C0G MLCCs: The High Capacitance Class-I Solution

    and high performance/price ratio, BME C0G MLCCs are starting to replace film capacitors in many applications. One such example is coupling and decoupling capacitors in audio devices, where low distortion and absence of microphonics are critical for high-fidelity sound quality. Another application is high performance bypass capacitors

Ceramic Capacitor: MLCC, X7R, C0G, Y5V... » Electronics …

    The ceramic capacitor gains its name from the fact that it uses ceramic materials for its dielectric. Within the ceramic capacitor family there are many forms of ceramic dielectric that are used: common types include C0G, NP0, X7R, Y5V, Z5U, although there are many more.

C0G (NP0) Dielectric | KYOCERA AVX

    C0G (NP0) ceramics offer one of the most stable capacitor dielectrics available. Capacitance change with temperature is 0 ±30ppm/°C which is less than ±0.3% C from -55°C to +125°C. Capacitance drift or hysteresis for C0G (NP0) ceramics is negligible at less than ±0.05% versus up to ±2% for films.

The problem with the ceramic capacitors is that the only dielectric accepted in signal path is NP0 (C0G) but the highest capacitance available for such capacitors is around 0.47uF at the moment. If you parallel two of them you should be fine. At 1uF the alternative would be film capacitor rather ...

Selecting capacitors to minimize distortion in audio ...

    Selecting capacitors to minimize distortion in audio applications Introduction The use of capacitors in an audio signal chain is often fraught with mysticism and little quantitative analysis to justify capacitor selection. With many capacitors costing more than the integrated circuits they serve, it is a chal-

Signal distortion from high-K ceramic capacitors - EDN

    C0G capacitors in 0805 packages were also tested and provide the exact same level of performance, and were removed from the graphs for simplicity. The increase in THD+N above the filter’s corner frequency is expected as the filter’s attenuation decreases the ratio of the signal’s amplitude to the noise floor.

Choosing capacitors for audio path - Q&A - SigmaDSP ...

    I would only use ceramic capacitors in the audio path where performance is not an issue, but size and cost are your higher priority. NP0 and C0G are the best of the ceramics, however I don't think you will find these types available in appropriate values. You will also see some references to film capacitors for use as AC coupling in audio.
