KZG Fakes?

[Brian C]

Sometimes great capacitor like Chemicon, Robycon, nichicon or Sanyo can be fake capacitor. Recently I bought a P4 mobo ( Asustek P4P800-X ). The mobo is made in China, althogh the VRM capacitor is Chemicon KZG type, I wonder they are fake chemicon cap produced by local manufacture...

Why am I thinking so....

First... the capacitor are not in same height. ( Please see the picture )

Second .... the capacitor are not from the same batch ( please see the picture ).


How can a motherboard have few diff. batch no of same capacitor type. Next time I will avoid buying made in China mobo.

Not relevant to the capacitor showdown, split into its own thread.

Interesting indeed.

Re: KZG Fakes?

Where are you located and where did you get the board from? I've never noticed that with any other Chemicon caps....

Re: KZG Fakes?

They seem to be a slightly different color as well. The ones closest to the edge are a darker brown, the others are a lighter, more reddish color.

Also, the font seems a bit different (Width mainly). I'd venture that you've got some fakes there.

The date/lot code format on that row of mauve caps looks wrong. The two with
5(7)
7Y
look right. The caps with
5 6
S(3)
look wrong, specifically the row location of the character in parenthesis.

hmmm.
looks suspicious to me!
i would think anyone wanting to produce convincing fakes would at least make them all the same size and get the code format/font right!

Re: KZG Fakes?

Well... I am from Singapore and I purchase the mobo from a retail shop, after my old mobo spoilt... ( the VRM controller (Intersil HIP6301) burnt ). I replace the IC, but the protection transistor still pull pin 8 to GND.

Actually, there are countless of fake chemicon caps out there. If U visit chemicon website, u will see the "Buyer Beware" message.

I've quite a number of counterfeit cap sample (taken from PSU, mobo, TV). Will upload the photo for all.

I viewed this thread again --> https://www.badcaps.net/forum/showthread.php?t=2701

I compared with KZG pictures in Indonesia market here.

Re: KZG Fakes?

What's wrong with the caps in the picture (KZG pictures in Indonesia market) ?
Are they fake...
Can't tell from the code/marking..
The marking is 4(k) 5R. The meaning is:
4: Year 2004
(k): Chemicon Indonesia Factory
5: Month of May
R: Day 18
Pls refer to this thread for code interpretation: https://www.badcaps.net/forum/showthread.php?t=3072

There's been an earlier discussion of the differences between real and fake Chemi-cons, but the situation is complicated by outsourced manufacture (by Samyoung and others) of various series that look different from the original Japanese caps, but are nevertheless authorized and authentic (most of these have the wide-indentation tristar vents).

The only safe fallback is to stick to the Japanese-manufactured NCCs, which have a shiny aluminium surface, a thin indentation tristar vent, and a small v or triangle mark in the channel between the leads.

By that criterion, all the caps on that Asustek motherboard have wide-indentation vents, and are therefore suspect.
