Warning : Fake large electrolytic on eBay !!

Some one else pointed this picture to me.
And I will share it with all of you.  :)




If you do not have a good DMM that reads 10.000mF or more, do not delay about getting one.

I've seen this picture before.  And each time I see it, I think, why
would you use a high quality Rubycon capacitor in a fake capacitor?
Why not use some other no-name cap?

Unless the Rubycon capacitor itself is a fake and there's a smaller
capacitor inside of it....

That's sounded funny,  but if you are correct, the one who did that, he must be some one who has lots of hate about electronics. LOL

The Rubycon likely came out of some used equipment, and has used most of its life already.

and you caution other people about sensational titles, this very picture has been around for a long time and was already discussed. I really thought you had found something new !

Why yes I would like to see a Matryoshka capacitor.  ;D

I don't understand how this could be profitable. Consider the time required to find old discarded large caps carefully disassemble them then solder in a small cap and put it all back together.

Easy - you pay Chinese wages and sell the dodgy caps for discount Western prices. You can pay unskilled labour less than US$1 a day in China.

The picture is obviously fake but what it symbolises is true: there are many counterfeit capacitors around which have much less capacitance than specified on the can.

No, you can't. But you can get ignorant comments on web forums for free!

I think the last time this was here, we decided it was probably like Russian dolls, with a capacitor inside a capacitor, and another inside that, and another... All the way down to a tiny 10pF. I suspect the capacitors are sourced from India or one of the African countries where scavengers strip down bulk containers of imported equipment and sell off the parts.

Lets stay on topic ... Please !!

As European I never had care if the American worker gets 1$ per hour or 100$.
And the wages part, has nothing to do with the product prices.

All that it matters are to be informed and careful,  personally I got fooled locally when I got a belt for my trouser,
from one of those Pakistanis who sell items on the street, it supposed to was an belt made by leather,
and it was common compressed paper with just the exterior to was looking like leather.

I payed 10EUR for it, that is 15$,  for the price I was expecting to was leather even the cheapest one,
, but paper ??   :)

LOL, you ask people to stay on topic and then write 3 paragraphs on a cardboard belt made in India.

actually all of them you name it, brandless or branded, cheap or expensive. even my eevblog tshirts :P. they all do look wear out after sometime of use. about the rubycon caps, i dont need a meter (mentioned in 1st post) to know if there's smaller caps inside or not, i can tell from its weight, i got many caps here the same size as posted, i got used already to how much they weigh. nahh, see?! oh wait.... 8)... i should get a uCurrent as a free gift for hitting 3K. and remember, its "on-topic", "usefull" and "sensible" one! "IMHO" :D

In the world of RC electronics, earlier this year fake Futaba GY-401 Gyros were discovered. They had cheap gyros inside them and a big nut to raise the weight just like in the Magical Hard Drives.

I don't know I've also seen pictures of counterfit TO-3 transistors even the cheap 2n3055.
I know but that doesn't change the fact that the image is fake.

I've seen this image many years ago. Here:

http://www.telemaster.ru/fuflo/

This site is about various fake components. Most of them are bought in Russia (Moscow market at Mitino). I suspect that these fake capacitors really existed but aren't from eBay. All other photos on this site are photos of components really bought by somebody.

The "expensive" Rubycon capacitor is most likely fake (rebranded) too. I've seen lots of them in Russia about ten years ago.

There exist even fake chicken eggs from China! Very hard to tell from outside and having something like coloured gelatine inside. Why faking them?.. They're cheap...
The difficult we do today; the impossible takes a little longer.

Gall thanks a million, about your reply, an reply direct from the source of the information.  :)

Thankfully there is no fake electronic spare parts in Greece, probably due the European rules,
makes every one more skeptic about doing such tricks, and another reason could be that Greece is a very small market for big scams,
about low cost items.
