is it right value

hiii ....
I have question about value of capacitor
is a 0.027uf ciramic capacitor and value = 27000p (273)p
is it right??
0.082uf is it (82000) p 823 p
and
0.001uf 102p
and
0.0027uf
0.001uf
etc..

To convert microfarads to picofarads you use a factor of 1 million, or 10 to the sixth power. These days, many use nanofarads, which uses a factor of 1000. So a .01 microfarad capacitor is 10 nanofarads, or 10000 picofarads. Just move the decimal point the required number of places, using zeros to fill gaps (or removing leading zeros) where appropriate.

If you are going to use that circuit with an AC adaptor i would use a 12V adaptor and use another 7809 to the the 9V which should be much cleaner. IF you are going to use it with a 9 or 12V battery permanently that configuration is just fine.
 21st May 2010, 04:27 PM #5 JO12   diyAudio Member   Join Date: Mar 2010 I bought ceramic capacitor for 0.027uf written on capacitor (( 2E273K )) and another one for 0.082 (( 2G823K )) is it right and what dose 2E***K mean ceramic capacitor like this green one

 25th May 2010, 12:07 PM #10 kroto   diyAudio Member     Join Date: Jun 2009 Location: Bandung I've been seen an article on wikipedia about capacitor coding (also with color code). go search there, it may help you much. If I wasn't wrong, 2E for 250Vdc and K for tol'+/-10%. __________________
