Hi Matt,

We use almost all ceramic caps for smaller values.  The package sizes I 
have used are 0603 and 1206.  And we have used values as high as 10 uF 
in special situations.  The only down side is the obvious... the bigger 
the capacitance, the lower the rated voltage in a given package size.  
If you are dealing with small voltages then this doesn't really matter.  
But we like to de-rate any capacitor's rated voltage by 50% in any
