Paulo Cesar, what is the number on top of the coil just to the right of it?


Sorry about my delay on the answers...

The number of the coil is 2R2.

I don't have time this passed weekend, I'm still looking for a supplier because is really hard to find a supplier of this components in my country (Mexico City).

On the other hand I discovered that also lacks the component FDFMA3N109. The description says: Integrated N-Channel PowerTrench® MOSFET and Schottky Diode.

And I don't know if this can also find on sale.


But the project about repair the iPhone sounds great, so do not desist as soon...


I appreciate your questions and answers oldturkey03 you keep abreast and any suggestions, i'm listen carefully.



Paulo Cesar, I just checked on and the part number for your component is FDFMA3N109TR-ND unit price is Unit Price 0.20400. If you need to, I can try and assist you with the purchase of the parts. Just email me, my email address is in my profile.
