Product review (3 stars): Your really buying a 370V Capicator (not a 440V), but it can work fine for most Air Conditioners.
This capacitor is smaller than manufacture replacement. I receive an email from seller trying to explain with a non-technical analogy between a 440V and 370V (a weak reasoning between a Farrari and escort vehicle). They were not obviously technical.

What it comes down to is that V=IR  (Volts = Current X Resistance). Volts and Current are always constant, so you only have Resistance to adjust..... which is the difference between the 440V and 370V.

Thus, I received a 440V (labeled) with the size of a 370V size Resistance.  It is working fine.

Most Air conditionairs require 250V minimum, so a 370V Capacitor will work.  (The just need to correct their Ad)
