How to Pick Audio Capacitors – Charrette & Beget

A typical ESR for a capacitor might be .1Ohm, whereas a low ESR model might be .01ohm.Low ESR seems to be a much touted feature for audio capacitors, especially Black Gates. Since resistance is not dependent on frequency, however, I don’t understand how ESR would have any effect on distortion in the audio signal, and I doubt you’re going to hear a difference …

The best capacitor types for audio circuits are polystyrene and polypropylene. Polystyrene is the first choice, but are only available in values up to .001 uF. Above that value, polypropylene is the type of choice, with nearly the same qualities of dissipation factor (DF) and dielectric absorption (DA) as polystyrene (these are the two capacitor “qualities” that most …

Polyester capacitors and electrolytic capacitors are some of the capacitors that give the lowest THD. In the case of Class II dielectric materials, X7R offers the best THD performance. Capacitors for use in audio equipment are commonly classified depending on the application they are used for.

For a +4 dBu sinusoidal signal, that's about 1.23 V peak, for a +14 dBu signal, about 3.9 V peak. The capacitance of class 2 capacitors, especially small SMD types (which are good at filtering RF interference due to their small parasitic inductance), can easily change by a few percent due to such a signal level.

There are two common topologies used in line filters: the X and Y capacitors. Due to risks of fire and injury in the case of malfunction, X and Y type capacitors are subject to additional safety regulations. X capacitor. X capacitors are connected across the line of an input. This topology can be seen in the schematic below:

Usually, a 0.1µF ceramic capacitor, or value around that range, is placed after the signal that contains both DC and AC signals. And this capacitor filters out the DC component so that only AC goes through. Filter Capacitor Circuit To Filter Out AC Signals

To start selecting the best capacitors for power supply filtering, you need to get into a capacitor datasheet and delve through some specifications. Some of the important specifications are as follows: Capacitor material: Your capacitor might be a ceramic, electrolytic, tantalum, polyester, or other material. This determines the useful capacitance range, as will as …
