[sdiy] C0G capacitor size differences?

[Mattias Rickardsson]

Speaking of component imperfections,

do you know if C0G (NP0) ceramic SMT capacitors get better (more
ideal) with bigger sizes and/or with larger voltage ratings?

The far less ideal X7R ceramics have a much heavier voltage variation
in smaller packages and in lower voltage ratings, grab a pillow and
see the scary graphs here:
