Quick answer no, that is why they have different "ratings" and types.
I tried figuring out why I'm getting the behaviour on Wikipedia and other places but I don't really know anything about circuitry. I've built a circuit following a diagram. I can find problems in circuits IE cold solders, and more recently blown capacitors. So I have recently come into a new project. Fixing a 22" widescreen monitor. The original owner said they heard a "pop" that they thought was a message coming in via facebook. I immediately thought it was a blown capacitor but I don't know anything. So they gave it to me.
Anyway, enough background. I took the thing apart and checked for obvious signs of damaged circuitry. I found a capacitor that had one cold solder lookin solder. There is also a white stuff that seems to be on all the capacitors that was severely cracked. The guy at "The Source", think Radio Shack, said it was some sort of paste. So I took to Google and figured out a way to test the capacitors with a multimeter. Using the ohmmeter I would see a gradual increase until it overloads whatever setting it's on. For the capacitors of the exact same rating and voltage, in the circuit - 220 μf 25v 105 deg. C - it takes about 2-3 seconds to overload 200kohm setting. I bought a "variety pack" of capacitors at the source because they don't sell singles anymore. I looked through the packs till I found one of the same rating, 220μf 25v 105 deg. C. After I found one, I put it back into the circuit, using the PBC board markings to make sure I put positive and negative in the right holes. I turned it on and I got nothing. I took it back apart and tested the capacitor. This is where things were weird for me. It takes about 10-15 seconds to overload 200k ohm setting on my multimeter.
The capacitor is the same height as the original but it is much fatter. I would say about 2x the circumferance. OR about 1.3 to 1.5 the radius. [EDIT]It looks that way but it's circumferance is about 20% larger on the new one now that I've measured it.[/EDIT] Does this have an effect on the overall circuit? Would a soldering iron heating up the capacitor have an effect on the capacitors ability to function?
I would say yes if it reaches 105 deg. C but like I said, I know nothing. I'm a programmer by trade... more of a learn as you go type hobbyist. Maybe I should use a heat-sink when connecting the capacitor. I checked all the other capacitors, they all behave the same, overloading quickly.

IMAG0065.JPG is the circuit board with a green - and + where the - and + terminals should go.
IMAG0067.JPG is the two capacitors. the black one(top) is the one that will not show any resistance when hooked up to the miltimeter, the brown one(bottom) is the new one that takes too long to charge. You can see the "white stuff" I was talking about on the black one.

There are two more capacitors with "mushroomed" caps that I'm going to replace. I hope that's the end of it.
