I've got these caps from my local distributor.
I'd like to know they're reals Nichicon HZ or fakes?
please help me identify them.

I have several bags of HZ's and their printing looks more copper colored than yours.

When compared side-by-side to Pana FM's, the FM's are brass/gold and the HZ's are copper.

Could be the lighting/flash.

Seems they're 4 years old too. Date code on mine is H0918

Here's a quick pic from some of mine.

EDIT: FC - FM - SE - HZ

These could be possible real HZ.


If I use these HZ 1000/16V caps to replace those others crap brand caps 2200/10V on PSUs, would be better or worst?

Usually it is not recommended to replace caps and reduce their capacity.
For what I have read on Badcaps it is better to replace with same size or greater size (+ 20%~30%).
If I were you, I would not udersize the caps, probably I would use 1500/1800uF not half of the original capacity.

Consider by Yourself . See attaches (not my pictures).
These amber coloured ones are all fakes that passed my hands, i replace them pronto, iff occur. The original HZ series, as You may see on the PDF too by the BW gradient, has the traditional grey-on-black colour.

The ones in your pics are HN not HZ. That's an iMac G5 mainboard.

Those are not fakes. Those -were- a known bad cap along with the HM series. Seems that Nichicon got caught in the bad electrolyte mess back then.

Excuse me, i wasn't enough punctual at searching.
So any of these amber-coloured Nichies aren't going well. They have sometimes much worse graphics on-printed, and the vent hole isn't as well-made (you can see these on high res images easily) as on other ones. I am still unsuire if they are real nichies, as the series are present, but none of them has these issues on the exterior design. Has Nichicon any white papers about this?

None that I've seen, but PCBONEZ has done more resource information than I. He may shed some light.

For better or worse, buying from an *Authorized Nichicon* reseller (according to their website, is the best bet. ANY cap, as we have come to see, has the possibility to be forged.
