Gary:  While not straight to the point, I recall a thread talking about ... "1825 and larger
should not be used on FR4 due to the CTE missmatch on a ceramic part that large, however the
1812's should be OK. Yes we have also run a 2225 caps on FR4, but as a general DFM rule we
have tried to stick to below 1825 for use on FR4."
