Hello, good afternoon.
I have received a FUNWORLD 4S-1A REV 1.0 motherboard with several damages by hits.
One of the hit has broken the D45H2A transistor and possibly the inductor connected to this transistor has also been damaged.
The inductor has some cracks and is possibly not damaged since it provides continuity with the multimeter but I want to buy new ones and I have problems identifying the iductance value with the color codes.
The third band has a golden color that I think is not real.
I wanted to ask you two questions:
1.- Is the inductor really damaged even though it has cracks at one of the ends?
2.- What value does inductance have?
Thank you very much for your help and regards.
