Someone trying to fake Capxon... Priceless

Re: Fake primary capacitors

I know this is an old thread but wanted to share some...These caps came out of Coolmax, L&C, Sun Pro, and Logisys PSU's

Re: Fake primary capacitors

Wow, more fakery (is that even a word, btw?). I guess from now on, when I see primary caps from unknown Chinese manufacturer, I will just assume the capacitance is 1 level lower than what is printed on the sleeve. Even though it may not be the case for every cheap cap brand, I think it's a safe assumption regardless.

Re: Fake primary capacitors

That's a good assumption. Unfortunately it depends...Another 470uF HEC input cap that was black instead of blue was actually 470uF. And a CS cap that I figured would be fake was its actual value. I wish they were more consistent!!!

Re: Fake primary capacitors

Weird!

Or, WHAT THE HEC!

Even the fuhjyyu is overrated! :P

Re: Fake primary capacitors

The Fuhjyyu is actually within tolerance (barely...), so it isn't necessarily fraudulently labelled.

Yeah you're right. I measured the other one that ran along side it and it measured 433uF so I assumed they were really 470's I should have posted the picture of that one

Re: Fake primary capacitors

No-one would be dumb enough to fake a Fuhjyyu. Although, one could probably dress up a Fuhjyyu as a KZG and no-one would know the difference.

Re: Fake primary capacitors

People have to remember most manufacturers don't care about Fuhjyuu caps -- they use them because they're cheap. And I'll bet they're easier to fake as there's less vigilance over them. So if supplier X suddenly has a large supply of Fuhjuuu and the procurement manufacturer can get a raise by dropping the per-unit cost by 20 cents then you will see fake Fuhjyoo.

Re: Fake primary capacitors

I found these fake Rubycon snap-in units in two identical Chinese power supplies.
Officially, Rubycon USP only comes in 85C whereas these fakes (both USP series) were labelled 105C.

Haha well found!

Got any esr specs and capacitance specs for the fakes? (I.e., are they actually 100uF?)

Re: Fake primary capacitors

Those are some decent looking fakes. Also curious to know their actual capacitance

Notice the wacko vent shape on one of them!

Re: Fake primary capacitors

The JEE 330uF 200V primaries which came out of this trashed King World ATX-250W PSU measured at 202.8uF and 198.8uF respectively, both with an ESR of 0.07 ohms and a date code of 9828. No doubt they are 220s with a 330uF label, as they are still in tolerance of said capacitance.

Same again with Su'scon. The two 470uF 200V LXs I ripped from an L&C LC-230ATX were measured at 312.0uF and 319.9uF respectively; both 0.06 ohms ESR. As with the above caps, they are well within tolerance... of a 330uF capacitor. This PSU was also from 1998.

Yeah true! But they probably had plastic discs over them though?

Wow that's crazy, doesn't surprise me though from L&C

Re: Fake primary capacitors

That line through the side of the 'Mercedes' vent looks like they tried to turn it into a K shape to match what a Rubycon should have.

Re: Fake primary capacitors

They are still doing this. Cap was manufactured the first week of 2013.

Fake one LOL

KMG sleeves are supposed to be brown not black xD
