    Because it has a fixed value ?

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

    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.
