What are the Decoupling capacitors? How to select Decoupling / Bypass capacitors?

I forgot a lot of this stuff from my undergrad. Thanks for such a great refresher!

[@FoolishEngineer]

You're so welcome!

I've always had trouble with electronics and they don't teach everything in the class, so I have to rely on KZbin videos to help me out. This one definitely solved some confusions and misunderstandings! THANKS A LOT!!!

[@electroquests]

Awesome video, I didn't know that the dynamic loads caused current spikes even if the input is pure DC, although it may seem obvious, we forget such minor but important details while dealing with projects where the requirements are stringent (For ex: Instrumentation), I'd say it's a trap for beginners and hobbyists, keep making such videos, they are very helpful!

You can get this graph in the datasheet of any capacitors before selecting.

I saw on my home stereo main board, between the tone control IC (it is TDA7442 by ST) and the audio amplifier IC (it is TDA7297, also by ST), there is elco connecting between the two +ve & the -ve placed near the audio amplifier TDA7297 IC, both on the Right input (R-IN) & the Left input (L-IN). What are such capacitors used for AC? As we know, audio is AC signal. For DC, we may understand as your explanation.

[@mohammadk9144]

Great Explanation. at 7:52 how do i know or how do i measure the frequency of noise?

[@amadouabdoulayedieng8987]

By doing a FFT (fast fourier transform) on an oscilloscope or any signal treatment tools you can identify the parasites frequencies. Though my answer maybe very late 😂

[@mohammadk9144]

I always wondered why do we add both electrolytic and ceramic capacitors at the same tyme as bypass capacitors, even though the net capacitance wasn't much changed. I only thought in terms of capacitance value and not the different properties of these two different types of capacitors . But well, i got the answer now. Thank you Foolish Engineer.

Thank you so much for this video, great animations. How can I calculate the value of the decoupling capacitor? Does it need to be in resonance with the noise frequency?

[@FoolishEngineer]

You will have to measure the frequency of the noise and accordingly, you will have to select a capacitor which has very low ESR at that particular frequency. But this is a very tedious process, you can read the datasheet of the component which you are using they might have suggested the Decaps for their chip

there are no calculations as such. you need to select caps based on the noise in your system.
