    Someone posted this picture to a Bulgarian forum, I thought it
    would be of interest to this group.

    Can this be real?! Although why not, I hear there are plenty of
    fake pharmaceuticals, after all, so why not some fake caps...

  2. Why bother putting anything in it at all? If it was hollow, it would
    at least meet the voltage spec.

  4. Wow, new to me!
  5. I didn't think anyone would bother counterfeiting low value items, but
    that's apparently wrong.

    Counterfeit Cisco hardware:
    More links at bottom of page. I've gotten a few of these boards which
    actually work for a few days and then blow up.

    Counterfeit electrical products:

    You can inscribe "counterfeit any_product_you_can_think_of" and Google
    will find a warning, victim, or customs seizure. This looks like an
    interesting resource:

    Note that it is perfectly acceptable to sell inferior Made in China
    products, but not using established manufacturers names and
    trademarks, which is counterfeiting. Thus, a junk replacement no-name
    cell phone battery is acceptable, but the same battery with a label
    made to look like it was from a US manufacturer, is not.
  6. Well, at least the capacitor is protected from leak and explosion.
    I am just wondering if there is another smaller capacitor inside the

    I got some fake Analog Devices parts. It should have been an
    instrumentation amp, but got something else inside. All the stampings
    on the outside were official AD and AD confirmed the markings. We had
    a buyer who liked to buy from scalpers until I did a review of a
    purchase trail on my project.

    Curious! Google search doesn't find a company named "Master" as a
    capacitor maker, though Rybycon certainly is listed.

    Checked Digikey pricing; 100 piece, cost differential ~ $1.00US, for
    6,800uF 50WVDC 85C versus 2,200uF 35WVDC 85C. In production
    quantities, might expect $0.20US to $0.30US differential. Given non-
    zero costs to make fake shell, solder cap onto leads, close package,
    etc., doubt counterfeiter makes more than $0.01US each. Pretty low
    margins! Can't imagine anyone doing this in less than ~ 100,000 piece
    quantity. If photo isn't a hoax, gotta be a BUNCH of fake caps sold!

    I suspect that the scenario might have been that they had an order for 50V
    6,800uF caps and already had the 2,200uF caps lying around... or could acquire
    them for next to nothing (far less than the "new" price). Then they're
    probably making better than $0.10/ea, which is pretty respectable.

    It is weird though... and I like the one guy's suggestion that you should
    check to make sure you aren't just getting Russian dolls!
  11. Plenty of outgas vent space there...

  12. Not all the claims on that page are legit.

  13. Or maybe it is rubycon that had millions of bad caps from the bad cap on
    MOBO days that they wanted to recover a bit on, so they made a fake
    company shrink on, and used some of their standard cans, and had the caps
    marketed by someone they had an agreement with.
    All profit 'cause it doesn't even et into the books, and the bad caps
    were already written off as losses once.

    Triple bad.

    That must have ruffled some feathers.
