Help to identify tiny 4 pin chip on motherboard of iMac a1224
Hello i am trying to repair an Imac with lightning damage. The model number is A1224 which is a 20" screen model.
I would like to identify the chips circled in red.
I suspect these chips are leabelled by FL9400, R9400 and R9410 on the PCB and may be related to that Delta ethernet transformer LFE9287.
I have already found out that the other blown chips '0524P' are diode arrays manufactured by Bourns part number CDDFN10-0524P.
The overall location of these chips is just above + to the right of the right RAM slot see picture in step 9:
So far i think they might be some sort of common mode choke but i would love a link/part number so i can source replacements. It was lightning damage and i have tested PSU unsoldered mosfets, caps etc ad tested with multimeter and t is working to spec now i try to fix the motherboard.
thanks in advance.
Is this a good question?
