Re: Mica losses
Good EXTENDED FOIL mica capacitors can have Q's of well
over 1000 at 1 MHz. Not sure where your loss data came from, but
doesn't sound right to me. My copy (4th edition here at home) of the
ITT Reference Data for Radio Engineers gives the dissipation factor
of ruby mica as 0.0006 at 1 kHz, and 0.0003 at 1 MHz. I have used
lots of silvered mica (should have same loss) in filter applications
where, for all practical purposes, they performed as if lossless.
