[R-390] storage question

[Barry Hauser]

Chances are the low temperatures won't hurt anything, but the changes in 
temperature at certain times of the year with the combination of high 
humidity may result in condensation.  With commercial gear (and some 
military) the moisure from condensation may contribute to surface corrosion.

I would suggest, if possible, sealing in plastic bags -- in dry 
conditions -- with some dessicant bags tossed in.  Not sure where to buy new 
ones, but the old ones from mil packing can be rejuvenated by drying slowly 
in an oven.  When sealed in with the equipment the dissicant will absorb out 
any residual moisture.

On the other hand, maybe excessively low humidity will dry out your 
capacitors ;-)
