Hello CCD World,

We are using preamplifiers next to the CCD inside the dewar´s for 10 jears. 
We had never problems with outgassing components. The temperature of the PCB 
is between -60C and -80C. For small values we use NPO and COG capacitors. 
You can operate these even at 10K (Radioastronomical Application). Larger 
capacitors are of the type MKT. (Tantal is also possible)
A simple check is: Measure the capacitance while you dip the C in LN2.
