[TowerTalk] ICE-419a Bandpass filter

[Mike Schelly]

The current stock #407 I just received has the DPPM series (1000pf) @2kv for
the "resonator" caps (in/out). The CDV30FJ102J03 may be a better choice for
RF though these are 1kv rated. ?¿?

Yes, I "misplaced" mine already in the chain. Regardless, change the
"series" mica(s)to the CDV16 series if a failure occurs...

I don't know how stable polypropylene would be at 14 MHz in a tuned circuit.

The ones I've used successfully in the past are the mica CD15, CD19, CDV16
and CDV19, all on page 838 of the Mouser catalog. Use Mouser.com search on
those terms, and more values will show up than are shown in the catalog.
