This was pulled from my microwave -- it was being flaky, replaced this filter with a new one, and found out that this board hadn't been the problem (it was the main controller board).  But...I couldn't return the board I didn't need.

This board with the fuse costs over $170!!  My loss is your gain -- this board was not at fault.

Make SURE this is the right board for your microwave.  The only model that I know for sure uses it is Thermador's MBES/01.
