Maximum voltage of ceramic disc caps

[atferrari]

I need several .1 uF disc caps to filter voltages around 33V.

From all I got, I found two, explicitly marked 50V. The rest is like those in the picture. The green one has 7 mm diam and it is some 3 mm thick, maximum. The other is 5 mm diam and less than 2 mm thick.

Any chances they are suitable?

Cannot smoke-test them. The sole available supply with 33V is the one being built.

I think that 50V is about the typical value for disk caps, so I think you will just have to try it. Either it works or not

If you are concerned about reliability, then I would just buy some capacitors with a known voltage rating. They are cheap.

What I did not like was to wait until Monday.

I think you will be safe, assuming this is a hobby level project and not a commercial order? 50v is standard for ceramic caps and 33v is very unlikely to ever hurt a ceramic cap.
