Hi Paul!
There are non-inductively wound ones specifically for the purpose. The
mfr. specs should show an ESR curve - the non-inductive ones are pretty
flat to their SRF.
I notice some of them come with one end tinted red (or sometimes black).
Does this indicate the non inductively-wound type?
Nope. That just indicates the "outside" foil - commonly goes to ground.
