Effect of over voltage Operating the capacitor beyond permissible limits of over voltage will damage the capacitor. Some levels of over voltages are accepted only for a short duration but they reduce the life of the capacitor. Such levels must not occur for more than 200 times in the life time of a capacitor. Protection of capacitors

Capacitor manufacturers are quite helpful in printing the maximum voltage their caps will stand before they stop being capacitors. You generally can exceed that a little bit, a few percent, at the cost of capacitor lifetime. If you exceed it by 10s of percent, then you''ll find your capacitor lifetime becomes zero.
