Default Re: capacitors in series - pitfalls?

It should not be assumed that the leakage current is a linear function of the voltage across the capacitor.
I was just about to make this point too...

I have found that paper capacitor leakage is more like exponential than linear.
Electrolytics behave a bit like zener diodes.

I think this explains why people get away series connection, but it does mean that one of the components will be stressed out somewhat while things balance up, so resistors are still a good idea in my opinion.
