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

I got a bit paranoid and measured all my big, lightweight caps.  ::)
Nothing like the smell of rosin core solder in the morning.

Are there any other dominicans on this forum?

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.

I don't know I've also seen pictures of counterfit TO-3 transistors even the cheap 2n3055.

No disrespect but it is true. Lots of sources here's just one recent one. Why do you think its cheaper to ship all raw materials there to have a product built then send it back.

ALERT: China's Manufacturing Sector Labor Cost Approaching US$1 Per Hour

http://blog.cu-bd.com/alert-chinas-manufacturing-sector-labor-cost-approaching-us1-per-hour/

They are starting to demand higher pay now but the lax environmental laws as well as worker health and safety laws which are pretty well nonexistent will still make it profitable to operate there for a while. It was the same in every country before the labour movements which is starting to happen in China so I wouldn't work myself up in a tizzy over it.
