Burden's Surplus Center (surpluscenter.com) offers two 5 ufd "motor run" capacitors:
and
They are very different in physical size.
Can anyone here explain why that might be true?
The voltage ratings are only 250 VAC and 330 VAC, not much of a difference....

The two capacitors are built with different dielectrics. The small one is probably a metalized film capacitor. The big one is an oil filler paper or film dielectric cap. The bigger one probably will handle higher current and higher over voltage before failure. The smaller one will probably self heal small dielectric breakdowns by vaporizing the very thin metalization around the arc hole.
Now, tell me again, how did Noah capture those rabbits? ;-D
