Is metal/alu-can type capacitor more rugged?
Is metal/alu-can type capacitor more rugged?
(OP)
How true is that a metal/aluminium type enclosure capacitor is more rugged as compared to a plastic can/enclosure, generally? I cannot find any reference on the Internet.
Thanks in advance.

Electrolytic capacitors (metal can type you refer to???) wear out over time - period. They are never fully sealed as they very slowly produce hydrogen from the breakdown of the electrolyte. Almost all of this type are DC only.
Plastic capacitors, if your are referring to rectangular film capacitors, can have extremely long lifetimes. Film capacitors are not polarized and handle AC currents as well as DC currents. Some types of film capacitors are self-healing when exposed to short overvoltage spikes.
Now, if your are talking about oval can capacitors like motor-start or motor-run capacitors, these are film capacitors, however they are made to be inexpensive, and do sometimes eventually fail.
