yes that was my point I have never seen any 0603 capacitors marked
while 99.9% of 0603 resistors I have seen have been marked.
Some are, and some are not. It usually costs more to purchase reels
of marked SMD capacitors and not all are installed right side up, if
they are marked. I worked in electronic manufacturing for a number of
years, and saw them come in both ways. We always tried to get marked
parts, but sometimes they were unavailable in time so we had to go to a
second or third source. The markings are faint at best. I read them
through a stereo microscope and some required a small drop of IPA to
make the marking visible.
So why are capacitors less likely to be marked than resistors?
There must be a good story there.
Most 0603 resistors I see are marked. 3 digits are easy to read.
I sometimes have to work a bit with letters on the 1% parts. (That's
after getting out a magnifying glass. My eyes don't focus up close
any more.)
I don't remember seeing any 0603 caps with markings.
