surface mount device identification help requested

[midway]

Hey guys, i've got a Qlogic QLE2462 dual port 4Gb/s fc card that I'd
like to repair but it's missing a couple components. One looks to be
a surface mount inductor and has 1R0 on it. The other is a capacitor
of some sort but I don't have a way of knowing what its exact specs
are. I was able to repair a QLE2460 because it just had detached caps
that were still connected on one side but I'm not sure how or where to
order these components.

here are pics

The Inductor:

1R0 on a SMT inductor usually means xRy, where R = decimal point so 4R7 = 4.7, units in microhenries (uH). So thats probably a 1.0uH inductor.

The Capacitor:

Sorry no idea. If you know someone with a LC meter or capacitance meter you can desolder the known good one off the other card and measure it.

As to tolerances / current handling requirements, I don't know.

Can you look up the IC they're connected to - usually a cardmaker doesn't deviate too much from a reference design given by the IC manufacturer. The reference design schematic should give you a parts list down to the device manufacturer.

I usually buy my components from Digikey - you don't need any special account and they ship cheap/fast with USPS.

Good luck.

I was afraid I'd have to desolder the good one, but that should be relatively easy since I've gotten quite used to my heat gun now.
