SupeR-NovA said:the 104m capacitor means it's 0.1uF cap
the 471 it 0.47nF
use the formula:
first and second numbers* 10^third number*10^-12=capacitance
theres one problem with this formula if you do the cap that you claim is .1uf it comes out to be .00001 which is 10uF not .1uF and the .47nF cap will come out as 47nF or .000000047. So either you screwed up on the formula or you just aren't that smart no offense but giving bad information isn't a good thing since it could be the difference between a bad accident and a good circuit.SupeR-NovA said:the 104m capacitor means it's 0.1uF cap

Pain, the equation is correct.

Sorry to say this man but if the equation isn't wrong then your answer is take your calculater and find your answers then switch it to engineering notation. You'll come up with 10uf and 47nf.Ron H said:Pain, the equation is correct.

use the formula:
first and second numbers* 10^third number*10^-12=capacitance
104 = 10*(10^4)*(10^-12 )= 10^-7 = 0.1uF
Example 2:
471 = 47 *(10^1) * (10^-12) = 47*10^-11 = 470pF
One thing I'm still wondering about is the voltage rating. Take the 104M for example. It's a ceramic disk capacitor. Is there a way to determine the voltage rating ? Does the color of the cap help ?
Thanks, I guess I should have avoided the "big box 'o caps" at Radio Shack !
I'll go "shields up" if I use one in a circuit. I'm just starting out so will be mainly using 6V-12V. Anything over 9 and I'll make sure it has a stamp.

Painandsuffering said:ok 10*10^4=1,000,000 or 1M. Then you multiply this by 10^-12 and you get .00001 which is 10uF....!!! This is what my graphing calculator gets and what the scientific calculator on the computer gets and what about 3 other people here with me are getting so Your numbers are wrong man. Just trying to help the guy out so he doesn't mess up what he's trying to build with the caps.

Thank you, Tony. That was a typo. I edited my post to correct it.fat-tony said:
No such luck. Some of the capacitors have stamps (those large enough to fit the printing). Most just have the capacitance codes.Maybe the box o caps container has the voltage values listed?
