Making an Stampg20 card


I'm making my own stamp adaptor for and Stamp9g20 SBC. I need to make an Ethernet connector, to do so I'm using as a base documentation the schematics from the Stamp adaptor provided in the starterkit. In these schematics the ethernet circuit uses one coil (the one marked as L1) which have no value and only it's described as "SMD-Ferrit". Anyone can help me an figure out the value?

Thanks a lot
