Arduino MEGA2560 USB parts identification

The PDF version of the schematic shows:

Z1 and Z2 are CG0603MLC-05E. Google shows those to be Bourns ChipGuard MLC-series ESD protectors (varistor).

F1 is MF-MSMF050-5. Google says that's a Bourns PTC Resettable Fuse.

L1 is a BLM21 which is a 2012 size surface mount inductor. The schematic doesn't specify a value. Perhaps the design files do.
