So how bad are OST motherboard caps?

Re: So how bad are OST motherboard caps?

Some of the solid caps used in those Rampage III Formula motherboard have a dark brown or black strip on one side of the top and are marked:

FP
07Cx
101
16

Does anybody know what brand this is?

Nichicon (formerly Fujitsu) Functional Polymer. I think Asus custom orders them with that funny color scheme.

Except Nichicon doesn't make any caps with an "FP" on them.

I don't know if Nichicon makes them, or just markets/distributes them, but Nichicon is definitely in the mix somewhere, and they definitely say FP on them.

Custom color printing definitely seems a possibility. The MSI board I ordered recently had blue FPCAP to match the blue PCB. I looked up whatever series it was, and the datasheet showed the caps with red printing.

I already did.
Your response is out of context.



You were deliberating replacing crap caps on boards you ALREADY HAVE.

DUH, it would have been better to do some research and buy better boards to start with.

With Abit gone your options are Supermicro, Intel, or experimentation because it's hit and miss by the specific model with all other brands.

What are you talking about? I haven't bought any boards yet. I'm going through the process of picking out a board.

I'm sorry, but I don't understand what I've done wrong...

I'm just saying...instead of buying a board with crap caps and recapping, I could just spend the extra few dollars for a good board with good caps to start off with.

FPCAP is a subsidiary of Nichicon. They are red. Regular Nichicon polys are black.

The only one I can find using that marking scheme is Lelon but their catalog isn't showing a series that would have those characters.

I'm almost positive that it would be FPCAP... All the other FPCAP series follow that marking scheme...

The last character on the second line indicates the series. However, I can't find a datasheet for an "x" series. And the brown color would be unusual, but FPCAP in unusual colors isn't unheard of as I've seen it occasionally.

FP = FPCAP
07Cx = Manufacturing code of some sort, "x" indicates the series
101 = 100uF (10 x 10^1)
16 = 16V

I googled some photos of the Rampage III board, and they definitely look like custom FPCAP, which are brown to match the PCB color.

FPCAP is usually reliable, so I'm not sure what to make of them blowing on the Rampage III when overclocking. Perhaps it's a weak point in the board design. Asus isn't always known for the best designs, after all...though that is one of their high end ones. Perhaps the custom series isn't as reliable. Perhaps severe overclocking exceeded the specs for the cap.

Problem with that is several brands are now calling their caps FPCAP.
But I found it...
Fujitsu changed their name [of their Poly company] to FPCAP -BRAND- in 2009,,, and the markings match.
[Presumably that was just before they sold out to Nichicon.]

Problem is they had 10 Series of FPCAP Radials and they didn't use a Series mark on any of them.

They do, they just don't make it clear...at least I think they do...

The last letter of the 2nd line is a series marker. Unfortunately, the only way I've found to match them up is by looking at the images of the caps in the datasheets.

RE series is "a"
R7 series is "b"
R5 series is "c"
...etc.

I've always found this to be the case whether matching up specs vs. can sizes to datasheets, or ordering new FPCAP from mouser and digikey. No matter what the other markings say, anytime I order R7 there's always a "b" there. Anytime I order R5, there's a "c" there.

Cryptic as the rest of the markings are, I'm 95% sure I figured this particular out.

Re: So how bad are OST motherboard caps?

Good eye!
That's a new one on me!

That deserves a reference table.
[L8 and S8 appear to be the same series, just different diameters.]

RE-NS a
RE-R7 b
RE-R5 c
RE-L8 d
RE-NU e
RE-NE f
RE-F8 h
RE-S8 h
RE-HT n
RE-E5 q

The other 3 characters must be a date or batch code of some kind.


I wonder if the FPCAP Brand/Company folded in the Nichicon buy out or if they are still around?
I assumed they folded but their site is current with the Copyright updated to 2011.
