[sdiy] X7R, Y5V, Z5U characteristics

[Mattias Rickardsson]

Great little applet there, thanks!
Yes, X7R and similar caps are quite terrible in many ways when you
expect more or less ideal components. But C0G seem great, a totally
different thing. Has anyone had any problems worth mentioning using
C0G instead of precision film caps for timing purposes? I use them in
filters, oscillators... and there was much rejoicing.
