Re: Whats this?
very interesting. its a Fujitsu FPCAP ML series. Can find much info at all. Fujitsu say that low esr and esl enable the number of devices previously required to be reduced by 90%. reliability is 1000 hours at 85% humidity and 85oC.
so basically its a super low esr cap which replaces need for many caps.
is that from the Asus Rampage II Extreme?
what a sexy board that is.

Can imagine we will start seeing those on the backside of Mini ITX boards to save space in the future...
Also another reason why I still to Intel chipset motherboards as I've notice something strange through the years.... Intel chipset based boards don't have MLCCs or caps on the underside of the chipset but VIA, SiS, nVidia etc. have components on the underside of the chipset.Don't find love, let love find you. That's why its called falling in love, because you don't force yourself to fall, you just fall. - Anonymous

Re: Whats this?
On some older and junk boards yes, but these days with C2D and powerful Athlons X2's they do have SMD devices on back of the motherboards. That's proper design from need to have bypass capacitors extremely CLOSE to the chipsets to filter out noise.
Learn to handle boards carefully, please.

get used to mlcc under the chip in an effort to get them as close as possible to the core.thats also why there are mlcc on and under the cpu.

Re: Whats this?
It looks almost like a oscillator they use to have on old AT boards. I think then they were used for the cpu frequency somehow, all i know is that if you had a 50mhz oscillator (such as on my DSI 386 computer) that meant you could use up to a 25mhz processor. 66mhz oscillator=33mhz, etc...
Of coarse, if it was a oscillator, it would have a frequency rating printed on it.

Re: Whats this?
I agree. If it didn't have uF written you'd just dismiss it as one of those other non interest parts.
Nice to see so much space saved. Usually high performance caps are pretty big, atleast I've had trouble replacing some, most recently I've been replacing 25v 1000uF caps with equivalent high quality ones, but they're significantly taller, and therefore potential for unforeseen problems to occur. Particularly when putting things back together. Sometimes I just think maybe I'll pile up a few high uF MLCC their instead.Rubycon Rubycon Rubycon
