    Cap Identification help on LG plasma

    Hello all, first time poster, probably not the last, I am having trouble identifying some caps on a power board for an LG MU-42PM11. I have an old board with original cap, and a new board with replaced caps, which are a bit smaller. They are SMD aluminum around the 5-7mm range. They are 1/3 covered on top with black the old ones have the markings S0073, 33, 25F. The new ones have the markings 33, 25S., 8Z2. Now I think I am safe in assuming that these are 33uF and 25V, but that all I've come up with. Wasn't sure if anyone would be able to identify manufacturer and tolerance levels? Thanks in advance.

      As I know it is, ha. Problem is, is that I can't get a good picture with works camera, even though it's a 10MP. I'm not sure if this will work, but we'll see. This is what it looks exactly... besides the text

        I know what SMD electrolytic caps look like. The only possible way of identifying the brand of caps is by a good quality picture of the actual caps in question. Manufacturer's logos are an important clue. A 10 MP camera should be more than adequate for the job. Here is a picture of a pc board taken with a 5.1MP camera. Use a tripod to steady the camera, make sure you have plenty of light, and turn the camera flash off.

          Alright, well I am pretty sure there are no other markings on it. I'll see about taking 2 boards home tonight and getting some pictures. There isn't sufficient lighting here. Thanks for your help

            Here is a pic of the new capacitor

              doesn't look right.

              The old cap is much larger. I rather bump to 100uF 25V which is in that size as old. Or just solder in a low ESR radial electrolytic 100uF 25V instead with legs bent out and cut to size to sit on the pads and standing up. Plenty of room there.

              I have a vendetta against those SMD electrolytic caps of these types except polymers.

              Cheers, Wizard

                Alright, my next question would be, tolerance. The people attempting to help me at digikey/mouser have said that the F stands for ~1% tol. I am new to the capacitor field, so I am guessing a 10-20% is okay to slap in there?

                  Also, got one of the old ones off the board, it measures, 6cm, so would that not be 30mm (diameter.) Wish they had a digital caliper up here
