[volt-nuts] Oven thermal insulation

[Frank Stellmach]

Hi Randy,


80°C and 'highest stability' is simply a contradiction in itself. 
Therefore, if you really go for highest stability, please run your 
voltage reference at < 60°C only, best would be 45°C!

In this case, ordinary styrofoam is suitable, higher temperatures 
require poly sulfone, like used on the HP3458A reference board, or the 
VALOX(TM) plastic which is used for the LM399.
