Hi Ren, You are right, a single digit is the value in picofarads, 2 would
translate into 2 picofarads. if there are 2 or 3 digits the last digit is
the multiplier. 151 would be 150 picofarad (15 with a multiplier of 10 to the
first power). 102 would be 1000 picofarad or .001 microfarad. Hope this
helps. 73 de Jack

Hello everyone,
I've been having a heck of a time trying to decipher the code on an
assortment of capacitors I purchased from Radio Shack for a Regen receiver I'm
homebrewing here at the house.
Not sure where to start....
I know that the first two numbers are the value and the third number is
the multiplier, but what do I do when they only have 1 or 2 numbers printed
on them?
Secondly and more importantly, how do I convert from picfarads to
microfarads. I tried using a convert program I found on the internet, but the
results just don't seem right at all.
The numbers printed on the caps I have are as follows:
1
7
10
15
68
103
151
221
561 Ceramic
561 Blue plastic
I know the numbers translate into picofarads (at least I think they do),
but again I'm not sure how to convert to microfarads.
If anyone could help me with this I would very much appreciate it.
Thank you and hope to see you all soon,
Ren
