Chinese Counterfeit Capacitors

[mobyd]

Warning :
Just got some caps on fleabay and something didn't seem quite right so did a bit of (20/20 hindsight) research and found..
1: Nippon Chemicon don't make a 100uF 450 volt KMG cap
(the biggest at that voltage level in KMG is 47uF)
2: The KMG range is wire ended, not snap-in

An externally hosted image should be here but it was not working when we last tested it.

Wow. I have seen the transistor fakes but not the caps.

That is incredible.

You gotta be kidding me. Is that photo for real??

You gotta be kidding.. is that the first time you see that pic?

I have even recommended people use this method, when refurbishing old gear, to keep the original look...

I must confess, it is the first time I've seen that pic.

For re-furbishing old gear, yeah great idea no probs there. But to put a 35 volt 2200uF cap in a 50v 6800uF? or have I mistaken the photo as a fake rather than a restoration?

Guys
Do you think that the Chinese counterfeiters are stupid enough to put a Rubycon capacitor inside a fake ? A cheap Asian capacitor, perhaps. I saw this photo a little while back.
Perhaps it started life as an April 1 prank ?

I think I've seen original Chemicon KMG or KMH 4700uF/50v snap-ins, so I'm not sure that's conclusive. However, there are several other indicators, including bad fonts, that indicate that the pic shown in the OP is that of a counterfeit.

Only a fake Rubycon !!!

Perhaps it's like a Russian doll ? Inside is a fake Black Gate.

There is another indicator not obvious from the picture - the text "negative black" printed on the plastic sleeve, yet neither rivet has a trace of black paint. I hope there are no Chinese counterfeiters reading this gathering hints on how to make more convincing looking fakes

Why would a person counterfeit a Nippon Chemicon cap, because of its low monetary value and unpopularity amongst DIYers?

The most common counterfeits are Elna for Audio, Cerafines........
