The Compukit UK101 has several ceramic capacitors, all
marked 104Z 25V,
which judging by what I've found on the web so far makes them .1uF. My local
Maplins (sorry, that seems to be a swear word in some parts) only has 224Z
at 25V (I'd guess .2uF?) and 104Z at 50V, half the size.
What can I get away with? Or am I right in assuming I need to match exactly?
I am not up to date on capacitor markings, but I will say that it is
the capacitance that is important--that and the type of capacitor
(which implies inductance, leakage, and I am not sure whatelse).
The voltage is something you merely need to meet, exceeding it is OK.
Assuming everything else matches, I'd go with the "104Z at 50V".
