Identifying badcaps in a Xbox360

Re: Identifying badcaps in a Xbox360

I emailed Rubycon about MFZ.
They said it was a custom ordered cap and they don't have any data sheets for them.

Re: Identifying badcaps in a Xbox360

Why, did you try the "oven trick"? Oven trick is good for components with no thin plastic AFTER you have removed the electrolyitcs. You don't wrap it with a scarf and tinfoil, you strip the board bare, unsolder the capacitors, and then reflow it in the oven.

I don't recommend this with a 360.

im soooooooo glad i found this forum, hopefully i can figure out why this xbox wont turn on now

Re: Identifying badcaps in a Xbox360

Thank you. I was also starting to second guess this, and was genuinely curious what MFZ really was. I wonder if they use precious metals inside the electrolyte to get it that low.

If someone can find out what is the VRM on the 360 and what isn't (I'm particularly interested in the Xenon), it could be modded. My Xenon, and othermodels also have polymer caps already on the VRM, but if there's a chance that there's a capacitor on the VRM that's not polymer, it has to be replaced with half the capacitance. And capacitors that are not in the VRM have to be replaced with full capacitance. The MFZs are 2700uF, so they can't be replaced unless they're on the VMR circuit, because there aren't any polymer capacitors at that high a level AFAIK.

Re: Identifying badcaps in a Xbox360

Sorry to bring up an old post, but I ran across this thread in a search. The Rubycon MFZ in question is not simply a lead-free MCZ replacement, MCZ is already RoHS compliant. MFZ is actually lower ESR (7mΩ for 2700uF @ 6.3v) than any MCZ. There is no MFZ datasheet, but if you scroll down to page 8 (or just search MFZ) in this document you'll see the ESR rating:



AFAIK, the only 'lytic that can touch those ESR numbers is Nichicon HZ. I'm certainly not saying MCZ won't work, just trying to share some info I spent a good deal of time tracking down. I ran across a couple of these MFZs on a Dell XPS mobo oddly enough.

Anyone done a full poly mod on a 360 yet?

Re: Identifying badcaps in a Xbox360

that's why i put recycled in quotes,
but what i mean is that domestic electronic waste just goes to the local tip, it's only industry that disposes of stuff through "proper channels"

that old tv you see by the side of the road wont get any closer to china that a local takaway.

Re: Identifying badcaps in a Xbox360

lead (and mercury, berilium etc) effect people who live near landfill sites and incinerators,
only a very small percentage of electronic waste gets "recycled" in china - most goes in the waste like everything else.

much of it is open burned or dumped on the ground.
"recycling" is the removal of parts that will bring a few cents each before the rest is dumped.look at some of the youtube vids.

Re: Identifying badcaps in a Xbox360

That is correct. I emailed Rubycon and asked.
Custom and no datasheet. <- That's what they said.
Also said they are out of production now.
.

As someone stated earlier, MFZ is just ROHS-compliant (lead free) MCZ. The entire xbox360 is lead free, due to retarded politics. I don't see how this affects any children other than those Chinese who put the xbox together in the factories, and those who take them apart in the scrap yards.

Miguel, go ahead and replace them with what you have. The MFZ is most likely only taller because of a special request from Microsoft, or to compensate for the absence of lead. What you should have done is replaced them with polymers since they are available at that spec I believe.

Re: Identifying badcaps in a Xbox360

Ok thanks guys,

In that case i'll try them out see how it goes.

Re: Identifying badcaps in a Xbox360

The larger can is either to lower ESR or improve heat dissipation.
Regardless, MCZ are known to work.

Re: Identifying badcaps in a Xbox360

afaik mfz is custom and no datasheet exists.

Re: Identifying badcaps in a Xbox360

afaik mfz is custom and no datasheet exists.
so try your mcz and check for ripple.if not good enough measure voltage and use polys.i bet mcz are good enough.

Re: Identifying badcaps in a Xbox360

The MFZ are 2700uf, this will not work.

But here is a picture of the Rubycon capacitors I am replacing

Hope this helps make sense

Re: Identifying badcaps in a Xbox360

The MFZ are 2700uf, this will not work. Also where did you get your Rubycon MCZ, not off eBay I hope. If you did, they're fake.

The MFZ I am replacing are 820uF.

I got the Rubycon MCZ from this site.

Re: Identifying badcaps in a Xbox360

What did you order and what are you replacing?

Hi mate,

I ordered the Rubycon MCZ series 820uF 6.3V.

They are to replace the current ones which are Rubycon MFZ and nichicon capacitors both 820uF and 6.3V. However the current ones are around 22-24mm in height and around 8mm in diameter.

The MCZ capacitors I recieved are only 12mm in height and the same diameter

Re: Identifying badcaps in a Xbox360

Hey guys,

I just received my replacement caps from badcaps.

However they are significantly smaller in size to the original damaged caps.
By significantly, I mean nearly half the size of the original ones.

The specs are same but is it suitable to replace the damaged capacitors?

Cheers
