I need to access the gathered wisdom here ...
I am building a switched low pass filter for my full legal
160-10M solid state amp (1500W).
I have access to a number of free (from a friend) older surplus
Mica caps rated at 2,500V (a few are 3KV and 5KV).
I also stumbled across unionel.com where they have 1KV
Ceramic Disk caps for $0.32 each.
Questions:
1. Are the Micas likely to have drifted significantly in
value over time?
2. Is 2,500V a sufficient rating for this application?
3. Are series-stacked Ceramic Disk caps of the same value
(e.g. four 100pF caps for a 4KV rating) a good alternative
to achieve high power handling capacity?
4. Are Micas and Ceramics of the same capacitance, voltage
rating, and tolerance % equivalent components in this app?
