voltage - Which capacitor for DC blocking in audio ...
https://electronics.stackexchange.com/questions/182505/which-capacitor-for-dc-blocking-in-audio-applications
For audio applications (as opposed to decoupling) there really aren't any high frequency transients to deal with, so a capacitor with a self-resonant frequency well above the audio range should be sufficient. An electrolytic capacitor is of course polarized, and only useful if the DC+signal is always unipolar.

May 20, 2020. by Paul McGowan. For many, many years we blocked unwanted signals and voltages with capacitors in the signal path. These were appropriately named, blocking capacitors, bits and bobs of circuitry designed to keep everything from DC to turntable rumble out of our stereo reproduction chains. And then one day we focused all our efforts on removing …

Description: Inmet inner DC blocks have a capacitor in-series with the center conductor which prevents the flow of audio and direct current ( DC) frequencies while offering minimum interference to RF signals up to 50GHz. Similarly, outer DC blocks have a. Frequency Range: 0.1000 to 4 GHz. Impedance: 75 Ohm.

For blocking DC signal in audio applications, we usually use 20 ( H z) as our cut-off frequency. So the value of your capacitor depends on the second circuit's input impedance. Assuming the impedance is hi Continue Reading Related Answer Oscar Desmonteix , …

block DC current and pass AC current. This makes capacitors a fundamental building block in Radio Frequency (RF) and microwave systems. They are often used to create filters, generate DC protection, and to create bypass networks. Often designers use rules of thumb or approximate equations to link capacitor values to final RF performance.

I have tried an audio amplifier circuit where the 220 uF capacitor connected via the output to the speaker, it worked well. The dc blocking capacitor in the FM transmitter is 330 nF and also worked fine. bananasiong Hero999 Banned Apr 26, 2007 #8 Here's the formula for capacitor impedance: [latex]X_C = {1 \over 2 \pi FC} [/latex]
