 7th March 2004, 02:56 PM #1 diyAudio Member     Join Date: Sep 2001 Location: Pickering, Canada Please help a lazy man ! I am trying to order some caps, but the values in the schematic does not match the on-line parts search values; can someone please check my cap conversion values. a/ 47nf = 4700pf = 0.47uf b/ 1mf = 1000uf Am I correct? Thanks, Chris
 7th March 2004, 03:00 PM #2 diyAudio Member     Join Date: Oct 2002 Location: England No 4700pf is 4.7nf. Remeber pf is 1000 times smaller then nano, so you move the decimal place three times to the left as if there was a dot after 4700.0 ei once 470.00 twice 47.000 thrice 4.7000. one milli farad? I never seen that one before, usually caps are rated in micro farad uF. But for the sake of argument, yes you are right. A milli is 1 thousand time a micro. Bah thats not right edit! You get 1000 micro for 1 milli __________________ What the hell are you screamin' for? Every five minutes there's a bomb or somethin'! I'm leavin! bzzzz!

If the schematic is correctly done, yes. Beware, though, that some
people actually write mF when they mean uF (ie. microFarads).

If you are unsure, maybe you could post the schematic so we
can check what function the cap has and what value is reasonable?

Thanks, I will go and make sure that it is 1mF or 1uf.
