I know *that* :) 

I was wondering if they were good for anything of volt-nut interest!

Specifically the hermetic sealing idea. I thought since they are not
encapsulated they might be free of humidity induced strain or some such.

Since then Frank posted the price which was less than I expected. Pity
about the tempco though. I guess they could be temperature stabilised?
