Any Amp with I2S inputs?

a capacitor value of 0.68 μF - 0.47 μF - rated for 35V-50V see Chapter 5.5.

If you don't want surprises, don't use ceramic capacitors at the low-pass filter output. Use film capacitors, for example with MKP2 dielectric.

Sorry @cobby , I just noticed your answer.

Would you be able to give me a bit more detail on what you mean ?

I am preparing to place the order for manufacturing and I believe almost all capacitors were switched to Ceramic as you advised by JLPCB:

sorry for my late reply also, i guess you have the amp new in your hands.
according your list youre fine i guess, as most values are too big for COG anyway, X7R, X5R is good.
In the Audio path film caps or cog ceramics are to prefer of course, not sure if you have the space on the board for film.

Not yet ! Ahah
I have received quite a few feedbacks on the PCB design and I will incorporate the different feedbacks before going for manufacturing, so I will take yours into account too !

if your boards needs to stay small ceramics are maybe the only way to go.
film ones can become quite big easily and theyre mostly trough hole.
film and cog ceramics are way more stable then X7R and worse X5R.
it always depends on what theyre used for.
for the dc blocking caps one could basically take large value ceramics, even theyre not as stable, the value make them work in a region you dont bother anyway.
if there are 10uF used, may go for 22uF or even 100uF.
its not high end but it should measure well due to the high value.
on the output LC filter it matters the most to use quality, if you can fit a film cap there, the 1uF?, it would be good for sure.
if there is no space go for the biggest X7R ceramic you can fit with the highest voltage rating ill say.
