Missing capacitor near HDD cable connection on logic board

I have recently rebuilt a Macbook Pro A1286. When I got to the point of installing a HDD, I noticed a missing capacitor, very close to the HDD connector on the logic board. I can include a picture, and if I can determine the value of it, I believe I am capable of resoldering it on. Any help pointing me in the right direction is very much appreciated!

There are 22 machines in the A1286 line. Please give us the last thee numbers of your serial number so we can identify which one you have. Also posting a photo would really help.


I'm not sure how to attach an image, though I have one. I do not have the serial number as I am at work, but it is an early 2009 2.4Gghz 15 incher.


Serial number is- W891602XC6DZA


I'm having a bit of trouble finding a DLP11S rated at 90 Ohms. Is Digikey the place to hunt? And by the way, you are THE MAN!! I had little hope of finding this particular part. ifixit RULES!!

Andrew, double check your serial number. anyhow, what you are missing is not a capacitor but a Common Mode Choke Coil 90-OHM-100M DLP11S. Check here for the datasheet. It is part of the SATA connectors and SATA HDD circuit. Hope this helps, good luck.
