Only caps used for filtering power supplies need to be in the millifarad 
range, and these will be quite large (the size of an AA battery or even 
larger).  Caps used for filtering low-level electronic signals, 
especially at high frequencies, are often in the picofarad range (and 
will range in size between the size of a grain of rice to that of a 
small tablet of aspirin).
