Ceramic Capacitor Sound Quality

In fact this isn t so.

Ceramic capacitor sound quality.

Polycarbonate capacitors are stable for use in audio oscillators. Stamler from reading circuit design texts one would think that a capacitor is just a capacitor and that different types are interchangeable in practical use. Compared to ceramic x7r characteristics and tantalum capacitors the distortion level is low and high sound quality of set is achieved. Ceramic capacitors are generally not recommended for use as ac coupling in audio.

It seems to me that an ordinary capacitor under dc bias would behave quite differently. The capacitor group consists mostly of 0 01 uf film types because of the availability of a 0 01 uf teflon capacitor i wanted to include in the tests thanks stefano. They are attractive because of the size cost and low esr. A ceramic capacitor is a fixed value capacitor where the ceramic material acts as the dielectric.

However if the microphone effect in a ceramic capacitor is primarily a piezoelectric phenomenon then maybe your idea would work. The geometry of the capacitor doesn t matter at all to the sound so you can use any capacitor that is 1 3 9uf 2 rated 100v or more and 3 non polarized. Thd measurement data pulse noise can be reduced when used in a digital amplifier s low pass filter. A silver mica and a ceramic are also included so that the line up contains an example of most of the possible choices one might consider for a crossover or riaa network.

Replacing passive components to improve sound quality. Ceramic capacitors have low resistive leakage and are stable over time. Ceramic capacitors are in the main microphonic but polyester caps are not. If you pick one that is also low esr it would better approximate a perfect l c circuit and so in theory that might sound better crisper or punchier as the capacitor.

In any case i doubt that the audio quality would be adequate. However when most ceramic capacitors are biased the capacitive rating can decrease by as much as 50. Capacitors differ drastically in engineering performance and their sonic impact varies too. Standard capacitors are perfectly acceptable for audio and will rarely if ever compromise sound quality unless used beyond their ratings or a completely inappropriate type is selected for the application such as a high tempco high k multilayer ceramic in a filter circuit.
