Does anyone know the specs for the Inductors on this Mainboard?

I need to replace the inductor on the mainboard as I believe it is bad, keeps making a loud buzzing noise when plugged into power.

The inductor in question is the large one right next to the SSD connector.

The numbers on the inductor are:




Can anyone tell me what these numbers mean so I can find a replacement? I'm thinking the 4R7 means 4.7uH but I can't be sure. Any help would be appreciated.

dingofest, that is correct the 4R7 is 4.7uH. the "R" is like a decimal point. 226 should be the first two digits are the value and the third the multiplier. Now it gets interesting. The 226 would be:


X - First digit

Y - Second digit

Z - Power of ten

226 would be 22,000,000 = 22 x 10^6 (1000000)

Y69 is an anomaly to me, make sure that those are inductors
