I'm in the midst of repairing a Hi-8 camcorder (Sony CCD-TR-805e) and
have found (most likely) some capacitors to be damaged around the CCD
area.

They are all SMD type capacitors. Small silver "cans" with a thick black
marking at one side of the top. I assume this marks the negative
polarity, right?

On the top the values are written, but to be 100% sure I get the right
replacements I want some confirmation on this. Here's what's written on
the top of each capacitor and what I think it means. Is my assumption
correct?


Marking What I assume it to be
------------------------------------------------
C
1
50 1uF/50V ?


C
4.7
25 4.7uF/25V ?


F
10
16 10uF/16V ?


G2
47
4V 47uF/4V ?


D
3.3
35 3.3uF/35V ?


Note the "D", "F", "G2" and "C" lettering! This is what confuses me, not
being sure if it has anything to do with the value, the company that
made it or something entirely different.

I just found a photo of the type of capacitors that need replacement:

http://www.elfa.se/elfa/produkter/en/1666.htm
(they look like the smallest one in the photo).

I'm also wondering what kind of capacitor I should be looking for as
there are so many types to choose from. I assume that I probably need a
precision, high quality type since it's for the image part of the video
camera. There are low-impedance capacitors,dry aluminium electrolytics
and a bunch of others to choose from at different temperature ratings.
Here's a complete selection (look for the ones symbolized with a "Y" in
a black box, which denotes surface-mounted types):

I really just want something that is reliable and will last a long time
as I'll be taking my camcorder on a long trip abroad and can't afford to
have it fail on me.

Yes, I think you are right on the values and voltage of the caps. I would try to get the same type to replace them. I have seen that type capacior in some catalog, but can't remember whose catalog,
sorry.

The fact that these failed would lead me to look for
a different type, one that will last longer.
And not leak. (if that is the failure)

Yes, exactly. But I don't know much about technical specs for components
and the differences between them, so I need help here telling me what to
buy as replacements.
I can handle the rest myself.

I have not done much video work lately, however
what I have done leads me to the proability that if
you have to use surface mount capacitors the best
type replacements would be Panasonic HA, HB or
HP the last is non-polar, the first two are polarized.
Personally I would replace with KG type if possiable
these are not surface mount and I have no idea how
the circuits will respond to this but for audio, no
problem, they have worked perfectly replacing every
leaking surface mount capacitor and several others
that I have done. (and thats quite a lot)
