8. SMD Fuse for USB Input Protection

Aarav is designing a USB-powered embedded board. The board draws up to 2A from a 5V USB input. 

To protect the board from overcurrent and short circuit, he needs an SMD board-mount fuse at the input. 

Considering standard fuse derating practice, the fuse should be rated above the normal operating current so it does not nuisance-blow under normal load. 

The fuse should be fast-acting to quickly disconnect during a fault. 

He wants a compact 1206 SMD package for PCB mounting. 

The company's approved vendor list (AVL) specifies Littelfuse for circuit protection components, so the part must be selected from Littelfuse on DigiKey. 

Help him select a suitable board-mount SMD fuse from Littelfuse on DigiKey.
