LIFETIME ! AT HIGH RIPPLE CURRENT. That's the ONLY reason.


I am wondering if these are showing up in audio equipment, for example, for
phantom power blocking.

That would depend on leakage current.


A more reliable cap would prevent cascading failures.

Coupling caps carry almost no current and the concept of cascading failures due
to cap failure died about 40 years ago.
