An alternative to these legacy Mica's are:

Cornell Dubilier (CDE):

MC (100 to 1,000V) (1 to 2,000 pF)
MCM (300 to 1,000V) (1 to 1,500 pf)
MCN (500V) (33 to 470 pF)
MIN (300V) (1 to 350 pF.)

All are surface mount

Available from Mouser and Digi-Key

I have had good results with these, and they
are MUCH smaller than the legacy ones.
