A capacitor is not a fuse. Unlike a fuse it is undocumented how a capacitor fails. What I mean to say is: - when a fuse fails, it breaks the circuit and the circuit it safe. - when a capacitor fails, it may either break the circuit or short it. To prevent a capacitor from failing you shouldn''t exceed its rating.
