Can someone please tell me the purpose of L1 and C5 in this schematic?

The connector is for SD memory.
The cap seems to be an over sized decoupling cap. But if I had to guess I would say the combo has do do with hot swapping of the SD memory chip.
Does it reduce voltage spikes on the chip when it is connected?
