# Fake capacitors

It seems to me the cost of making a fake capacitor like this will cost the same or more as making a real capacitor. I have seen winding machines that make capacitors it would only take and extra 2 seconds to make a 6800uf vs 2200uf. It will take much longer to put a 2200uf inside a 6800uf case plus the cost of extra parts and extra labor how can the manufacture not be loosing money.

They make anything fake over there. Maybe the real capacitor was thrown away because it is defective?
What will happen when they begin selling their cars over here?

I've seen this picture posted many times but never heard of anyone actually seeing one. However, 18650 batteries are a definite problem.

#Metoo, and with that said, if someone was going to the trouble of faking a cap in order to make profit, would they really put a Rubycon in there?

They took good lessons from Americans.

Yep, this picture is from the web and has been around a long time.

I saw a youtube video on fake ICs.
What they showed is people heating up mother boards and banging then on the ground so the parts fell off. (smd) Or using a solder pot and pliers to remove parts.
Then a company gets the parts and re-tins the leads and re-burns the name back on the part. The leads are straightened . The parts look new but are old and have just gone through hell. It is also common for the new part number to show a new revision which is not true.

I once found a AAA battery inside a AA case. I don't remember where I got those batteries it may have been rechargables I bought on ebay or Walmart. Rechargable batteries that did not work as claimed, Eneloop batteries work great.

I used a Harbor Freight coupon to get a free bargain pack of AA batteries they are very light weight like balsa wood. They work but don't last long I cut 1 in 1/2 it was full of little white balls about 3/32" diameter. I never saw a battery built like that before.

I don't usually learn an item is trash until after I buy it and try it.

Probably a fake Rubycon .

actually, i've seen at least 3 or 4 of these. i don't know what distributor they had been bought from, but there were 3 or 4 of these in a part bin at a place i worked at. if you picked them up the right way you feel a slight vibration. if you hit them on the side with a screwdriver handle, you can hear the capacitor inside vibrating. i got curious and opened one up, and what i found was very similar to that picture. you have to keep in mind, a few cents worth of difference between the two caps might not seem like much. it's when they sell lots of a million or more caps to distributors or equipment manufacturers that the slight price difference makes sense.

Why do some people think there is nothing wrong with cheating someone else. It would never occur to me to do that. Bible says, love of money is the root of all evil.

More likely a used/scavenged rubycon installed in that contraption thingy and being sold as a new 6800uf.

Or possibly a staged pic...for whatever reason - maybe a relatively-modern amp project, designed to look old-skool?
Can't seem to find much info on that image, other than 'untitled.jpg'.

As far as I'm aware it was a VERY common scam, with Chinese crooks selling such capacitors for high priced audio construction and upgrades.

Are these the same people that bought oxygen free cables?

i think that originally came from badcaps.com, or from the diyaudio forum.

that's a whole other can of worms... i saw a comparison between teflon insulated, oxygen free, cryogenically de-stressed, pure silver wire, zero skin-effect (i'd like to know how they managed that one, because skin effect is essentially part of the physics of wire and cables) speaker cables versus a set of 6AWG battery cables, and there was NO measurable difference between the two in any way whatsoever. the only measurable difference, between the "fancy" cables and the battery cables was the price.... $300.00 per foot for the fancy cables and about$2.00 per foot for the battery cables.

But "they" could hear the difference.
