[AMRadio] Help with silver mica marking

[Rick Brashear]

GOT IT!  Google revealed my needs.  "J" is the tolerance and the "D" in "FD"
is the working voltage which in this case is 500 wvdc.

Thanks.
Rick


I have some 220 pf silver mica capacitors with the following markings:

CM05FD
221J03

I know the 221 means 22 X 10, but is the J the tolerance or voltage rating?
Been too long...

Thanks for all help..
Rick/K5IAR
