Check "Partsconnexion".
They have several sources of axial foil and film caps.
Expensive!  Intended market is DIY HiFi.

Don: Those devices were designed for the leads to remain basically parallel
to the ends of the devices. Bending them 90 degrees all the way to the case
stresses the outer dip and in some cases cracks it.  I don't know what such
cracks do to the moisture seals.

Sure, I can (and did) put a 90 degree bend in the lead away from the case to
make them work, but they aren't as well-supported as if they were true
axial-lead caps, and they look like what they are: the wrong part for the
application.

I don't know anyone still making real axial-lead foil-and-film caps.  If
someone knows a firm making them, point them out.

The comments from you and others on ESR for ceramic vs. foil caps were right
on the money, and I appreciate them.
