for design by companies such as HP, and on the Voyager spacecraft, that didn't allow electrolytics except where absolutely necessary. And the other sort were cheaper and crap - they suddenly died after 10 to 20 years.</span></div>

so they don't die after 10 years, but the aging process of aluminium electrolytics is now well understood and it's much easier to design a product to last a long time.</span></div>

I had found that one as it happens, but I concluded it must be the<br>
wrong one, because Mike wrote "TI paper examining how you can use X7Rs<br>
in most critical audio pathways" while the article says "For<br>
high-performance applications, use C0G/NP0 capacitors when available<br>
and film capacitors when practical" -- so I figured he was talking<br>
about something else. But maybe I'm being stupid about it.<br>
<br>
Mike -- can you enlighten me?<br>
