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..
