Aliexpress capacitors?
Good, bad, fake or pot luck?
I know, if they claim to be a name brand but are too cheap, most likely fake, but if not branded?

I wouldn't, I've seen many cases where the caps are rated for a lower voltage than what they print on the sleeve and will explode if exposed to voltage printed on the sleeve

Any reason not to order from DigiKey, Mouser, CPC Farnell, RS Components, or LCSC (for electrolytic cap brands on LCSC I choose Cornell Dubilier, Kemet, Kyocera AVX, NCC, Nichicon, Panasonic, Rubycon, Suncon [not Su'scon], Taiyo Yuden, TDK, Vishay Intertech. and Yageo) (for polymer, you can use just about anything on there with a datasheet). -

Fake Nichicon capacitors with an almost-perfect sleeve?
Same font, perfect logo, same size of the sleeve. The air vent looks okay. The diameter of the capacitors is correct per datasheet.
It truly looks like the real thing.
I doubt that you would distinguish it from a genuine one.. if it wasn't for the bung.
Shall we be afraid, at this point, that even the bung can be replicated?... -
Hi,
I have capacitors like this one in the photo. There are differences between other Elna series, I attach foto of Elna RE3. On this green capacitors series is not specified! Fake?... -
Hi, I have some 32 bits computer motherboards that need repair, as they fail to
power on.
Here are some examples :
(N.B. "capacitors" indicated here are electrolytic capacitors located in the onboard
switching supply area).
(N.B. #2 : I could not find a 3300 microF aluminum-polymer with a higher voltage
than 6.3 V.)
1 - Motherboard #1 : this is an Asrock K7VT2 (socket A) that still works well. To put it on test
I replaced capacitors with aluminum-polymer.
3300 microF/6.3 V. x 4 replaced by 3300 microF/6.3 V. (KYOCERA... -
hey all, iv got my favourite battery charger here which iv had for many years probably 15 years now or maybe even more. it still works good but thought id open it up to clean the dust out of it, lots of dust inside but now its clean and noticed 4 capacitors inside it and wondered if i should replace them.
it has inside:
2 x 47uf 16v caps 105c branded as Su'scon (lol sounds sus to me)
2 x 470uf 16v LZ105c branded as G.Luxon
not heard of these brands are they any good?
iv attached photos of the charger and the board inside for an idea on the type of... -
I did not have any 27uf @ 50 volt capacitors but one nice thing is that it has enough room for two capacitors in parallel a 22uf and a 4.7uf @ 50 volts 22 plus 4.7 equals 26.7uf which so very close to 27uf I will show some pictures of it sometime tomorrow
This is one of the shit est boards I seen in a very long time and it was the daughter board the traces just lifting off the board I had to use the capacitor leads to repair the the traces and the main board is not any better because I had to repair several traces for the daughter board to the main board
After all of...
