Since you don't know what component it is, how did you come to the conclusion that it is burnt?

You can see it with your blind eye. My friend!

It's a ferrite bead. It is used for noise suppression. It looks like the 5V TVS diode didn't do its job, or perhaps something on the 5V rail has developed a short. Measure the resistance between ground and each end of the component.
