[R-390] r-390A capacitor question?

[David Wise]

I'm behind the times.

X7U is rated for bigger temperature extremes than Z5U but the same capacitance tolerance, meaning it *may* be more stable but no guarantee on that.

A casual search yielded half a million hits, about four times as many as Z5U, the ubiquitous junky cap of my youth.  Looks like it has replaced it.

Hi

It's a valid dielectric these days.
