I was looking for replacements to recap an SE/30 motherboard, and noticed that Panasonic has announced new type (Conductive Polymer Hybrid Aluminum Electrolytic Capacitor) of electrolytic capacitors that are supposed to be longer-life and higher reliability due to a different design. They are not out on the market yet. There were some comments made in other threads about tantalum caps having the disadvantage of having catastrophic failures. Any thoughts out there?

Also, does anyone happen to have the physical dimensions in mm of the larger axial electrolytic capacitors?
