Be 6.3uf 47v or be 47 uf 6.3v this is the question

Polarization is a limitation caused by the dielectric, not a wanted behavior. So, it doesn't matter.

correct

Hi Caius,

I'm not sure when >1uf ceramic smd caps were introduced. But that's probably recent.
Could be why Sharp does not use them (they does not exist at all in these era).
But even nowadays, I've never seen them in newer design.

Kinmami suggestion is valuable, and will work. I agree.

I'm just wondering if in long term, it could not cause more problems than fixing...

ceramics are largely used in mobile and portable devices nowdays because of own reliability and durability.
X5r or X7R series can support from -50C to +85C, at 1MHz with low loss.
