Help me identify a component from EAGLE schematic
What you see here, is not an exact specification of a component. It is more an indication to select a component. 

It reads: The (complex) impedance of this inductor shall be 33 Ohms at 100 MHz. You have to select an appropriate inductor.
Z = jωL is the formula to use. 

You should take care of some more things. As this seems to be a power line for an USB port, the inductor should bear a continuous DC current of at least 500 mA without giving smoke signals. As many devices draw more than that, better go for 1 A. To keep losses low, the real part of the Impedance (i.e. ohmic resistance) must be below 100 mΩ I guess. This is called the series resistance in the data sheets.
