I have discovered that I have a burnt component on my Arduino Mega2560 board.

The part is L1 BLM21, SMD EMI Suppression Ferrite Bead.

I have tried to get a more descript reference but can not find what to replace the burnt one with.

On the RS Components site there is a wide range to choose from.

Any suggestions.

A ferrite is a ferrite. You are dealing only with size and shape for your application. Measure the one you have and find the one that matches and you should be ok. Ferrites however don't have power passing through them, so it sounds like the burnt component is adjacent to the ferrite?
