Anyone have an idea of the current rating for a .47uh inductor on a 7950?

[Bobs Yerunkle]

I broke an inductor off the card removing heat sinks from an aftermarket cooler.  
It isn't a difficult repair if I can find the right part.

Card: Sapphire Radeon HD 7950 21196-00-20G

The broken inductor from the card says
0.47uh
1211BR

The 1211BR part has been no help on the googles.

There are a number of inductors with a similar size and inductance at Digikey but I have no idea of what the current rating should be.

The part I am referring to is circled in red in this photo:

If anyone has a clue re: the inductor or a dead 7970 reference board they want to part with please let me know.

Much obliged.

Is the coil good or is it torn / cut? You can ask someone to re-solder it.

Unfortunately it cracked into two pieces.

Are inductors like capacitors, where you can use a larger current rating component without issue?  Just so long as you get the right microHenrey value??

Yes, I would think so.

Hey on this note

My GPU power cables come with 16v capacitors on them, when I make new cables, is it ok if I put higher voltage ones on there?  They would be the exact same kind except for the voltage

Would this offer any benefit or not really?

The reason I ask is because I'm doing it anyway and they are all the same price, so while I am at it, if it's alright why not just throw larger ones on there.

I don't know for sure, but it's probably this little guy:

This was the direction I was heading. I'll give it a go.

Are you going to use the pencil tip on a temp controlled solder iron?  I really hate working on lead-free components.  I usually end up removing all the solder I can and lowering my temps and going with 60/40 solder.  Is it through hole or surface mount?  The other bitch will be finding something that lines up correctly.  At least through hole you can bend the leads..

Another option might be to call Sapphire and ask them what the component is (perhaps a mouser or digikey part number, or at least the manufacturer and the current rating).   You'd be surprised how far a little honesty and upfrontedness can get you with these GPU manufacturers.  When I called Powercolor, the guy was practically floored that I fessed up to breaking the fan blades.  I was like "Yeah, I broke the fan blades moving some cables around in my computer while it was on, can I buy a new one?"  He said most kids call up and make up some lame story to blame them and get a free part.  He seemed to appreciate my honesty.  Granted, it wasn't a board component but a fan in my case... but maybe they'll offer you an exchange credit or something?

It's worth a shot.

Lot of months have passed but I finally got around to it so here is an update just for closure...

Replaced the broken part with this one: INDUCTOR POWER .47UH 14A SMD http://www.digikey.com/product-detail/en/IHLP2020CZERR47M11/541-1231-6-ND/2025171

I basically just grabbed the highest amp rating I could find in the same size.
The repair is still new but have been running tests for a couple hours and it mines and stress tests fine.

(I also contacted Sapphire at one point and they wouldn't tell me anything since it was 'proprietary' information.)
