Re: capacitors in series - pitfalls?
The quoted life of an electrolytic is at maximum ripple current and maximum temperature. The life doubles for each 10 degree drop in temperature. A 105C capacitor with a rated life of 2000 hours (83 days) has a life of over 14 years when run at 45C. In practice the life would be longer as the ripple current would normally be a lot less than the maximum.
