0steveastrouk 11 years ago Its VERY hard to tell sometimes . ANy ideas who made the capacitor ? I would have said 22,000pF , 22nF or .022uF, but you put the "." in. There is a KIND of convention that capacitors which don't explicitly say "10uF" or "100n" are marked based on pF - years ago there was an attempt to use the resistor colour code to mark capacitors too, and surface mount caps are very occasionally marked in pF too. Sorry I can't be more specific.
