Surface mount cap

[Mjolinor]

I have a need to replace a capacitor, value 22,000pfd 1206 package 200v 10%

I have a book of TDK samples but no data sheets and can't find the info on
the TDK site, physical size isn't a problem but I would think 200 volts is.
I don't have much experience of the working voltage of these surface mount
devices but 200 volt seems high to me for the size so, question, does the
1206 just refer to physical dimensions or does that specify the voltage as
well. I have 2012 in the right value but it is much smaller and I have 1608
which is a microscope job to even see it, will either of these do?

Those numbers just refer to the size of the capacitor, in 0.01s of an
inch. A 1206 part is .120 x .060 inches. 2012 would be .2 x .12 -
huge as SMD capacitors go. 1608 is .16 x .08.
