[time-nuts] Hermetic tantalum capacitors

[John Moran, Scawby Design]

When I was a lad designing telecom kit that had a minimum design life of 20 years, we used Sprague tantalum cased glass sealed capacitors that were treated like gold dust.

Sprague has now been subsumed into Vishay and they still do the same devices, stocked by Mouser and Digikey at reasonable prices, so long as you don’t go for the aerospace versions.
