Why specifically multilayer ceramics?  You'd have much better luck 
looking for film capacitors and they'd probably be a much better fit for 
your purposes, too.  MLCC are mainly used for power supply bypassing 
where ESR is a main concern as well as high capacitance-to-volume ratio. 
  Due to the typically large temperature coefficient and voltage 
dependency of their capacitance they're useless for most anything else.

Maybe start with understanding why MLCC exist, what applications they 
are targeted at and how they're constructed?


You'd then maybe notice that high volumetric density and leaded 
components don't really come together and hence distributors don't stock 
that sort of thing unless someone orders a truckload anyway.  Also, when 
looking at the temperature, voltage and aging characteristics you'd 
perhaps find that a 1% tolerance isn't something that makes sense to 
specify, either.


(on the road :-)
