Did I just bought a fakecap ?
 
4 Attachment(s)
Today I bought... I mean friend of mine bought capacitors that I ordered, as the shop where i bought it is too far away from me, as he isn't understands anything in electronics, he just bought it as I ordered. At first shop on their page showed 1800uf 6.3V Sanyo caps, with generic picture and code SY-1800(which isn't correct). After little bit of search I found out that it was WG 8X20 capacitors(p.s found that out before buy). Ok, ordered, next day friend gives me package with those caps and some other caps that I ordered. But... This were NOT the Sanyo WG, these were Panasonic(Matsushita) FL caps, which are not for public, so I can't find any datasheet for them... by dimensions these were the same 8X20 caps also I cound't measure ESR or Capacitance, as I don't have needed tool for that. If you have Panasonic FL 1800uf 6.3V, that you are 100% sure are real, then send pictures here, also picture of mine caps are attached bellow(p.s i bought those for 0.41BYN/0.16$ a piece).

Я думаю, что ето поддельные конденсаторы. Цена слишком низкая, чтобь купить чтото нормалное. Я никогда бы етие конденсаторы не купил.
I think that these caps are just generic Chinese low end caps. The price is wayy too low for something decent. I wouldn't buy or use these caps for anything critical.

real, but very old.
FL was rare even when they made them - mostly only used on pc motherboartds.

Found out That logo isn't the same as on real panasonic(photo attached), i got mobo with real FL panasonics, logo is little bit diffrent, also color of this ones is black/white, while of fl which were used on mobo are black/orange. Also font with temp and series is too low on my opinion.

Согласен, тоже думаю что цена слишком низкая, но это был единственный вариант который подходил для моей материнки со вздутыми Rubycon MCZ

Agree, I'm thinking that price is too low too, but this is was only variant that would fit into my motherboard with bulged Rubycon MCZ

p.s these are photos of mine Asus P5B-VM where original caps are located but they are 3300uf 16V, forgot 'bout them, now I',m 50-75% sure that these caps are fake.

replace MBZ or MCZ with polymers

Eh, too late, this motherboard is crap mobo which costs 10$ max, and I already spent alot on it, so I'll just go with those caps, but which polymers you will recommend me then, it will be helpful in future for me :D

Also what can I say, is that our shops isn't selling caps more than 1500uf, and they cost 2.11 BYN/0.83$ each, and that alot for price of this mobo

i use cheap ali-express polymers.
even crap ones are better than the best electrolytics :)

Oh, for real ? I think I heard somewhere that some polymer caps are just normals with new sleeve :D Maybe you can give us a link to them?

Re: Did I just bought a fakecap ?
 
polymers dont have a sleeve, or a vent on top.

whoops written it little bit wrong, i meant that were some FAKE polymers on Ali so I'm tbh little bit afraid of them, but still, can you give the link to Ali for this caps

fake polymers? you mean fake maker or fake as in, they arent polymer??

That they aren't polymer

Re: Did I just bought a fakecap ?
 
i cant see it, they would need a cap factory and polymers are shorter so regular electrolytic guts cant be inserted into a polymer casing.

the only shit electrolytic that gets mistaken for a poly is the infamous FZ's

Well I think I'm talking about those FZ's then, but you that these guys can fake anything :D Maybe it's Just a rumors that I heard sometime ago, I hope so then.

there is no need to fake modern parts.
china is the worlds electronics factory - they have lots of "surplus" ;) from pcb production lines. :D

*Update*
Those caps didn't survived, maybe they are still working but they are bulged(Screen attached)...
They didn't survived because they got overheated(common problem on this ASUS P5B-VM board, saw another one for sale with same bulged caps, screen attached by the way), even original factory Rubycons MCZ didn't survived this one, so those caps wouldn't get even a chance either :( Also near are Kemet A758 caps which I bought from same seller, they are still good(0.67 BYN / 0.27 USD each btw), they replaced 3 bulged and one none bulged Evercon 330uF 6.3V which were installed from factory for some reason... So maybe you'll give me an advice which poly cap to use for this board, as I didn't found any 1800uF 6.3V poly cap on Ali.

Check the polarity of the capacitors: you installed them backwards.
Asus are crazy and uses the half circle on the PCB to designate the positive side.
See for example:

how wide are the 1800uf caps? 8mm or 10mm

they dont always do that - which is actually worse because you need to note the details before you pull the old caps - or go searching for pictures afterwards.

Funniest of all that K58 Kemet caps survived...

And the board worked for a long time... You know... 3 days...

xnRS 06-06-2021 06:32 AM

Re: Did I just bought a fakecap ?
 
So, after desoldering caps what I got is:
3 died panasonic(probably not) caps, each of them lost half 800 uF of their capacity(Finally got at least LCR-T4), and got high ESR
1 out of 4 Kemet caps died on desoldering, as one output lead desoldered(or what it has done) from the cap too. Other Kemet caps survived and still got good ESR in range from 0.07 to 0.11 and 360-380uF capacity

a polymer with 0.11ohms sounds so wrong!

they are 330uf 6.3v, will check the datasheet for these Kemet A758

So from datasheet it says ESR at 100 kHz 20C is 16 mΩ

0.016 is a lot less than 0.11 :)

best i'v found in 8mm so-far is 1000uf, but i'm still looking :)

I think this is would be hard one, as polymers are more wide and more low, so I found only 10mm 1800uf one...

stj 06-07-2021 05:24 AM

Re: Did I just bought a fakecap ?
 
1500uf will be fine, but i suspect we wont find more than 1200uf.

Of course they're fake.

I have never seen Panasonic FL sold to the masses that were genuine, nor are they even manufactured any longer.
