You have any pictures of them? -
Re: NCC KY 6.3V 470uF
I located them on ebay.. Based on the data sheet they appear to be 330uF based on dimensions.. These are from egecku / pcmcs..

Re: NCC KY 6.3V 470uF
Although it's certainly possible that they are fake, this guy is well known for selling non counterfeit caps. More likely it's just a specialty size made for an OEM that didn't use them all.
It's actually pretty common. I have a nice stash of UCC KY 3300uf 6.3v in 10x30mm, that don't exist according to UCCs data sheet. They are quite genuine, identical in every way to the UCC KY 2200uf 10v
caps I got from Digikey, right down to the luster of the aluminum cans.Comment

The 3300uF 16V samxon RS caps don't appear in the datasheet, but they weren't fake. They were just a custom sizeI love putting bad caps and flat batteries in fire and watching them explode!!
No wonder it doesn't work! You installed the jumper wires backwards

Re: NCC KY 6.3V 470uF
The 10mm RS?
I figured this was the possibility.. Just odd I guess since the dimensions match 330uF.. I've never had badfakecaps from this seller so was curious..Comment

If you commit to the volume and pay the price (usually not horrible) "big boys" like Nichicon and UCC will do custom parts.PeteS in CA

Will it damage the macbook?... -
I decided to take one of the Rubycon capacitors out of a phat Xbox 360 with a Zephyr motherboard and noticed that all the Rubycon capacitors near the CPU were fake. The capacitors in question are Rubycon MFZ 680uf 6.3V and they all have a bullseye bottom, something not found in genuine Rubycon capacitors. None of them were leaking, they all have the K top, and the system has never been opened before. It appears Microsoft was using fake capacitors in the Xbox 360, or the Chinese facility where the console was manufactured in was using them and passing them off a genuine. Just thought I'd share... -

I have 50 Chinese constant current isolated LED drivers based on LC6685 IC. 35 drivers are working fine, but there is a slight flickering in the rest of the drivers.
I have checked the output with oscilloscope and found that there is a slight random voltage fluctuation.
Is it possible to get the datasheet of LC6685 IC?
Also highly appreciate if you could let me know what could go wrong....
