Capacitor Conversion Table
« on: March 27, 2008, 03:05:18 PM »

OK, so I've got this handy little capacitor conversion table that I use when working with caps.  The table allows for quick conversion of cap values from pF to nF to uF, and vice versa.  It's also pretty helpful in helping to decode the little cap value code on each cap, i.e. a cap with the marking 223 is .022 uF.  I was wondering if anyone here would be interested in such a table to keep at their work area for easy reference.  I have the table in Excel and PDF formats.  I guess it would be easiest to somehow post it here so anyone who wanted a copy could have access to it.  Maybe even somehow post it to the Wiki.  It's a great tool and I'd be glad to share.

Reference material is alway welcome. I think the wiki would be an excellent place to park it.




FWIW: You can use Google to translate values between pF, mF and nF.

For instance, If you search for "250 picofarads in microfarads"

Google will return this...

"250 picofarads = 0.00025 microfarads"

Have you seen this? http://www.justradios.com/uFnFpF.html It doesn't tell the codes for caps but it's where I started. If you have any intress to share your chart, go a head every good info is welcome in here.

This page has the colour codes for poly caps listed (scroll way down). But there's a mistake on the page where it talks about reading three digit cap codes. It says:

Quote
So 100 would be 10pF multiplied by zero i.e. 10pF.

But 10 x 0 != 10, 10 x 0 = 0 !!! The third digit is a power of ten exponent. The code "100" actually reads 10 x 10^0 = 10 x 1 = 10. But the tables are correct.

I'm guilty of mis-reading units (ahem) but in my defense that was very late at night. Smiley Still, is the uF <-> nF <-> pF conversion awkward at first for Americans (or anyone else who didn't grow up with the metric system)? Once you remember the order the go in ( uF > nF > pF) it's just multiplying and dividing by 1000 to convert. Example: 47 uF is 47 x 1000 = 47,000 nF is 47 x 1000 x 1000 = 47, 000, 000 pF.

This thing's a bit handy sometimes:

And "number of horns on a unicorn"
Also once in a blue moon

I am building a replica of an old circuit that had a tropical fish with brown,black,yellow,white and red bands. What value is this as I plan on using orange drops. Thanks
