Ceramic Capacitor Sound Quality

Compared to ceramic x7r characteristics and tantalum capacitors the distortion level is low and high sound quality of set is achieved.

Ceramic capacitor sound quality.

Polycarbonate capacitors are stable for use in audio oscillators. Ceramic capacitors are in the main microphonic but polyester caps are not. High current impulse loads or high ripple currents can generate audible acoustic sound coming from the capacitor but discharges the capacitor and stresses the. Capacitors differ drastically in engineering performance and their sonic impact varies too.

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. Ceramic capacitors have low resistive leakage and are stable over time. Replacing passive components to improve sound quality. 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.

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. 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. The quality factor is defined as the reciprocal of the dissipation factor. However when most ceramic capacitors are biased the capacitive rating can decrease by as much as 50.

They are attractive because of the size cost and low esr. There are many factors but in a guitar application just about any modern capacitor works well. Thd measurement data pulse noise can be reduced when used in a digital amplifier s low pass filter. In any case i doubt that the audio quality would be adequate.

In fact this isn t so. A ceramic capacitor is a fixed value capacitor where the ceramic material acts as the dielectric. Ceramic capacitors are generally not recommended for use as ac coupling in audio. However if the microphone effect in a ceramic capacitor is primarily a piezoelectric phenomenon then maybe your idea would work.
