Help with identifying SMD comp - 4R7 011S

Hey guys,

I'm trying to repair my 2010 15" macbook pro as a project and need help identifying a particular component.

As above circled in yellow: 4R7 011S

From my understanding, its an inductor 4.7uH, of series 011. Thing is I cant seem to find the same component on element 14 or rs-online.

Isit really an inductor? do Inductors have 3 leads?

Bonus Question: Is this broken component somehow related to the RAM slots? I'm getting 3 tones during startup.

Thanks in advance to respond-ees.

Nicholas Chan, that is reference designator L7030 and it is a fixed inductor 4.7UH-10.2A listed as FDA1254F-SM but since it is Apple, it's a bit hard to find. Yes it does have 3 connections, it is part of the PBus Supply & Battery Charger circuit

Sweet. Thanks OldTurkey.

Just to make it complete and for future reference, I found the component "FDA1254" from the Japanese manufacturer 'Toko' >

THough there are 3 pins, the upper 3rd pin according to the spec sheet is a no connection dummy pin.
