[Lowfer] Interesting finding

[Stewart Nelson]

Hi Bill and all,

Check out polypropylene caps.  Excellent Q, high voltages and currents no
problem.  Also inexpensive.  Don't know if the temperature stability is
adequate for your needs, or if you can get small values.
See http://www.ascapacitor.com/PDF/polypropylene%20general%20information.PDF .

73,

Stewart
