Hi,

> blue ceramic marked: 224
Further to Paul's answer, there's more info on my resistor codes
information page (http://www.njohnson.co.uk/resvalues.html), including
what the letters for tolerance mean (in your case, "M" = 20%, "K" = 10%).
For what it's worth, I usually interpret them as "digit digit
no.of.zeroes". In the above, that would be:
> "10" and 4 zeroes => 100000 = 100,000pF = 100nF = 0.1uF, 20%
> "10" and 3 zeroes => 10000 = 10,000pF = 10nF = 0.01uF, 10%
> "22" and 4 zeroes => 220000 = 220,000pF = 220nF = 0.22uF
Hope this helps,
Neil
