Even Intel used bad capacitors

  1. I was given an amp once, burnt cap in the PSU. 7 other caps were fine, and
    the voltage was like yours, very slightly exceeding the cap spec. While most
    survived, the failure was spectacular. It's worth uprating to limit the odds
    to nearly zero because if it does fail, it might take out more than itself.
     

  2. Prove it, Ass. Between marginal components, the ROHS hoax and crappy
    designers, like you, it doesn't stand a chance.

  3. Maybe true, maybe not. Consistency is better, but that just means makers can
    claim better specs for a design. If they can make money by narrowing the
    spec margin, they will. You still need to uprate, just not as much. And where
    there is call for several similar parts with slightly varied specs, it is
    sensible to uprate to one common spec and save with bulk buying.
     
  4. It's logically correct. If we forget margin-pushing exercises, you have two
    choices, lower, or higher. Running at lower voltage is obviously the better
    choice out of those two. Not just better, but taking the other choice can
    cause explosions.

    It also comes down to availability and whether an item is bulk produced or not.

    Speccing a bulk-buy component against a similar one that is not in popular usage
    will affect the price you'd pay.

    Buying 105 Deg C rated caps where 85 Deg C will do the job with a decent margin
    is not good purchase practice, but you may well find that 'your' component is
    cheaper in the 105 deg C version simply because there is a huge volume going to
    someone like LG or Samsung.
