Yep that’s an inductor which is usually part of dc/dc buck converter circuit (switching power supply). In your case it’s 10uH smd inductor (there was 100 stamped on it, at least that’s what i can see on holybro’s site), not sure which dimensions, you can measure, but i would presume 0630 size ( 773MM). If it’s part of 5V power supply, check if you get 5v on the pad next to it. I would still replace it before flying.
edit: hmm looks smaller than 0630 … i’ve measured usb connector which is 7.5mm so this is smaller… measure it, then we can see what size it is.
