How do I read capacitor value

[thecritic]

I don't know how to read the capacitor values of ceramic capacitors that looks like this
**broken link removed**
Values I see are
a. 22
b. 100 AEC
c. 22
d. 102 AEC

etc.

When you get two digits like '22', normally it's in the pF range. Thus, you would then have 22pF.

When you have three digits like '102', you can find out how many µF's it is by counting back six digits. The third digit is the multiplier. Thus:

102 = 1,000 → 0.001000 → 0.001µF, or 1nF.

You can search google for tutorials on this.

Thanks for that.
But what I confuses me most is 22 and 22.
A bigger (relatively) cap has 22 while a tiny one has 22. Do both mean 22pF?

As far as I know, I believe that is correct. I'm sure the difference in size is due to voltage ratings.
