O_holter, romm temperature is around 20degC. It is hard to tell what is lifespan of the cap since different companies put different numbers. I would assume >50 years in 20degC. Capacitor will fail only if you leave it unpowered for many years. Cold capacitor has lower ESR.
Safety of Older Electronics
Some electronics never die. They just get moved to secondary, tertiary, etc. systems. In my case, I have two old receivers connected to televisions. I'm guessing one is 25 and the other 30 years old. The remote sensors are on all the time and occasionally one forgets to turn the receivers off. They can be replaced with relatively inexpensive amplifiers for how they're used, but I thought if it ain't broke don't fix it. At least until recently when I've started to wonder if continuing to use them is a smart idea even though there is nothing apparently wrong with them. I'm thinking in terms of a damaging (catastrophic?) failure particularly when the receiver is unattended. I'd appreciate input whether one should continue to use older equipment that can be inexpensively replaced.
