Default Fake Rubycon caps?

Looks like the ordinary rubycon (standard) caps:

Rubycon YXA, 2200uF 16v:




..except that the top and the bottom are more look like sanyo:






sanyo and rubycon in one body?




(i found them in an electric piano/organ made in china, iirc)

Exclamation Re: Fake Rubycon caps?

i feel tired. i feel empty. i feel angry. i was hoping too much for this cap, then it also turned out to be a counterfeit :






http://www.rubycon.co.jp/en/catalog/...inum/e_YXG.pdf



a counterfeit? wrong font? unmatched dimension with the datasheet?

i don't have an esr meter to test with...









frustated. i slice them with an axe. and look at the inside:

original YXF -> grey, juicy

suspicious YXG -> grey, juicy

original MBZ -> blue(!), dry

fake YXA -> dark

teapo -> dark

GSC -> white!

FC -> dark

jackon -> silver, juicy


still frustated.

Now that's dedication, I admire your curious spirit.

We've seen copies before (Rulycon) that tried to fake it, but these are really trying to come off as counterfeit ones.

Shouldn't people be looking into these sorts of things? Damn. This can't be good at all for Rubycon if it happens on a huge scale, and maybe they need to hear about it.

In a Tenma 72-10495 (Korad 3005D-2S rebadge), it had fake Rubycon USP series units (rated at 105C, whereas genuine units of this series are actually rated at 85C) for the input filter.
Although not fully shown, the fakes in the picture had varying vent styles.

Are those fakes? Bought new 2 or 3 years ago in local shop which mainly stock from tme.eu I suspect.

Readings:
SANYO (1500*6.3V) 0.13ohm 2.8% 840.7uF
Jamicon (1500*10V) 26pF
Other nonbulged Jamicon 0.03ohm 3.1% 1457uF

TME does not sell fakes, it is your re-distributor who most likely ripped you off. Buy direct next time. They also stock cheaper caps such as Elite...

The Sanyo caps are definitely fake, as they do NOT use a "T" vent. They use a "K" vent (different from Rubycon's, but still a K).

As for the Jamicon.... they may or may not be fake, though I think they are, as most Jamicon I've seen are black with blue printing. But either way, why would you even want to use Jamicon? They are not good at all. Only their DC fans are alright.

Ah, I see.
In that case, you're better off going to an e-recycling center and picking up some CRT TVs and monitors - preferably Sony and Panasonic as they use Japanese caps inside. Sure they are only general purpose 85C rated ones, but I trust them more than Jamicon.

They do, lol. But the caps are too small to matter.
