Rubycon series MHZ ?

[linuxguru]

Spotted a Rubycon MHZ on an Intel D865GBF (possibly installed on a previous recap). A search on Google reveals several listings on EBay claiming these to be Japanese-made ultra-low ESR capacitors, but no datasheet. A pic is attached - is this genuine Rubycon (maybe OEM only) or a counterfeit?

Looks legit. Is that PCMCS's eBay stuff? It seems he bought/buys overstocks and closeouts from the manufacturers. His Yahoo store is capselling.com .

Here's a older thread showing one on an Intel board:

Re: Rubycon series MHZ ?

Thanks - anybody got a datasheet of the Rubycon MHZ? It seems to be an ultra-low ESR aqueous cap with specs similar to a Nichicon HM - other D865GBF boards have a HM of the same value at the same location. The MHZ may well be a special-order series specifically built for Intel/Flextronics/Jabil/...

14 years later and I still am not finding a datasheet. I guess we were not suppose to have this information as of yet.

Reminds me of MFZ on XBox motherboards. But I thought I possibly saw one of those on a non-Microsoft motherboard.

Re: Rubycon series MHZ ?

Most Rubycons beginning with M and ending with Z are used for motherboards.

It's probably in the same line with MBZ, MCZ, but special ordered for specific manufacturers.

holy crap I looked up MCZ on google and my datasheet archive is the first link
