Nov 05, 2009· The 1st bought marked 221. Based on your table, that is a 0,22 nF (please correct me if i'm wrong). And the 2nd bought marked 10K and size bigger than the 1st, i assume that would be 10000pF=10nF. For the 10nF, wouldn't that be lot way to high to replace a 0,25nF. But both replacement size smaller than the real one, aka 0,25nF.
