    Possibly fake or just strange UCC caps ?

    Hi,

    Just bought these from a local online supplier. Do you think they are fake ?

    In the 1000uF x 10V KY I would trust, but the 820uF KZM seem suspect to me. Of course, I was disappointed, as the store sells the good brands ( Rubycon, Nichicon, UCC, Panasonic ) and the prices are not bad, although the price per order is still a little high.


    I could not get good light for the bung to appear, but it is a bulls eye pattern, not the two halves like the 1000uF x 10V KY.

      Yeah, those KZM look fake, the vent is different, the color is a shade off, and see how far the uf is away from the number? And the UCC logo looks a little off too. Seems like too many oddities to be real. Did you test their capacitance?

          The color is a little different, like they were on the sun for some time.

          Yes, what I noticed were the different vent, the bung and the separation between the u and the F.

          Sad. Well, I won´t be buying from that store again , also. I first thought about complaining to them, but I think they will just shrug and say they buy from the "best suppliers", and that the caps are from a "different factory" or "different batch ", "different model " .. Maybe I still will complain, but one doesn´t feel much at ease fighting with these online places that ask too much personal information when doing a sale....like with the telephonic companies, some charges may appear in a CC, and then one has to waste a lot of time and patience solving those "computer errors".

          Yes, they measured about 920 - 940 uF, while the 1000uF KY would measure something between 990 - 1017 uF. I think I will just keep those fake ones for using in junk atx psus. Too bad Farnell charges US$ 40 just for shipping here...

              The capacitance may be fine, but the question is the ESR and longevity? Probably not. The bung could be whatever supplier was cheapest on the day. Since they couldn't get the "mercedes" vent right they don't look to be trying to hard, just trying to fool the average customer?

                  Yeah, I think so. Most people around the city that I have talked to just buy 105C caps, whatever the brand, and use them. Difference between brands and ESR is an alien concept to them .. : (

                          Seasonic B12 BC-550 – barely 2 years old and with BAD CAPS already!
                          by momaka
                          I know I've been a little scarce lately (like the last 2-3 years), but I'm still here and still doing my thing with fixing PSUs.

                          For today's considerations, I have a Seasonic B12 BC-550 [A551bcafh] 550 Watt ATX power supply for you (click on links for full size images).

                          https://www.badcaps.net/filedata/fetch?id=3591772

                          It's a modern ATX unit with fixed (non-modular) cables and an 80-plus bronze certificate. Here's the label:

                          Heathkit IO-4205 Power Supply Caps
                          by eryjus
                          Hello,

                          First, I am a complete noob with high voltage stuff. I'm learning, but I need help by someone looking over my shoulder.

                          I recently came into posession of a Heathkit IO-4205 5MHz Dual Trace Oscilloscope. The documentation is copyright 1978. I'm told it works.

                          I opened it up to check the caps before I applied power, and found the following black caps and wanted to know what they were. They are on the power supply board. I was able to read the name and model and came up with, "Nytronics 162J-1, 0.1uF, 20% tolerance, 2000VDC."
                          ...

                          Identifying caps on an old Zoom 9000
                          by Paxman_Swede
                          Hello!

                          I have two projects on my work bench. One is a friends dead JBL Xtreme speaker with a blown voltage regulator and corresponding bulged and shorted cap. That cap has clear markings so I know what replacement I need for it.

                          The other project however is a whole different deal. It's a Zoom 9000 guitar effect from the 90th that has developed a devil hound howl when there is no input from the guitar. I'm guessing caps problem. So, since I don't really use this effect anymore I thought it would be a perfect project to learn on.

                          I have studied the board and...

                          Fake Caps in Xbox 360
                          by Galraedia
                          I decided to take one of the Rubycon capacitors out of a phat Xbox 360 with a Zephyr motherboard and noticed that all the Rubycon capacitors near the CPU were fake. The capacitors in question are Rubycon MFZ 680uf 6.3V and they all have a bullseye bottom, something not found in genuine Rubycon capacitors. None of them were leaking, they all have the K top, and the system has never been opened before. It appears Microsoft was using fake capacitors in the Xbox 360, or the Chinese facility where the console was manufactured in was using them and passing them off a genuine. Just thought I'd share...

                          Help with switching power supply caps
                          by captain150
                          I'm trying to repair two old VCRs, they both have bad caps. One has leaky ones, the other would barely run until I subbed in some caps from another power supply I had laying around (though they are the wrong values). This vcr works for an hour or two, but then the power supply starts whining and the picture gets lines in it. I didn't replace all the secondary caps, so another voltage might still be problematic, or the values I used are too far off.
                          I've been on mouser and digikey but the options are a bit overwhelming. I just need some new ones that will work. They don't need to be top quality,...
