The STM32F407G-DISC1 board has an inductor L1 'fcm1608-0603' for power supplying purposes but the value does not appear, which is its value?

Because it has a fixed value ?

Some while ago, I would perhaps have said 'Google Is Your Friend'. Not so sure anymore ...

 ,

 ,

But not even in the attached document is the inductance mentioned, I have

searched everywhere but I have not found it.

That component is not used as an inductor. It's a ferrite bead and meant to suppress certain frequencies. If you don't care about passing EMC tests you can use a short instead.

Ok, understood. By the way, in the document several are rated for different

DC resistance and MAX current. The one on the board will be a medium one

according to the current consumed by the uC?
