[R-390] capacitors and suppliers

Searching at Mouser, I took a representative value, 0.01uF, 630VDC-2KVDC, stocked only, and added "foil" to the search string.  This produced a couple of Wima FKP1 parts.  Changing "foil" to "FKP" yielded nine FKP1 and FKP4 parts, ranging from $0.76 to 2.69 .  The datasheets say they are film/foil.  If you are willing to go down to 400V, you can add one FKS2 part for $0.47 .

If you are 100% allergic to metallization, pass by the FKP4; they are foil/metalized film/foil/film.  That still leaves over half a dozen 0.01's.

Here are three more film/foil types that don't show up in the above search.

CDE type DMT
CDE type DPP
CDE type WMF

That last is even axial-lead, for you radial-haters.  All in stock, and nothing over about $3.

FWIW,
Dave Wise

PS - I left out Sprague type 715P since it is said to be on the way out, but they're still in stock.  About 1000 715P 600V, less than $3.  Casting a wider net, I see that some values are EOL status but not others.

All: The  note from Charles seems sound to me.  On the R-390A I did, I went
the all-OD route and regretted it almost instantly.  I had the experiences
that he cited.  Never had the courage to go into the RF deck, so mine is
still "incomplete" I guess.

The only places that seem to sell real film-and-foil caps, though, are some
rather esoteric hi-fi  places.  If there are better sources, I'm all eyes.
When I check manufacturer's websites (e.g. Vishay) I don't seem to find the
real film-and-foil caps still being manufactured as a product line.  I will
freely admit that my search has not been exhaustive.

Thanks,
