An interesting stat on electrolytic capacitor life expectancy:
Oh, and apparently they call it an "Output cap" in an SMPS - It's a "Filter cap" in a linear power supply (I'm no electrical engineer - I just like messing around with electronics).

(from: http://goo.gl/Kh3Dg)Electrolytic capacitors are typically rated for 1,000 to 5,000 hours of life at rated voltages and temperatures. That is less than one year !
