Hello, Im tired of paying for expensive universal capacitors to keep on truck. Can some of you guys with more experience recommend the most common size dual capacitors for residential condensing units to keep stocked on the truck ? It makes alot more sense to me to have these on the truck instead of making a trip to the parts supplier. thanks, Bob

Multiple capacitors placed in series and/or parallel do not behave in the same manner as resistors. Placing capacitors in parallel increases overall plate area, and thus increases capacitance, as indicated by Equation ref{8.4}. Therefore capacitors in parallel add in value, behaving like resistors in series.

slightly confused: capacitors from the same technology with different capacities but identical voltage rating typically have different volume. So, if two capacitors are comparable, but don't have the same capacity, they won't have the same volume. Or are you interpreting "size" differently?
For precise applications, a lower-tolerance capacitor should be chosen since a higher-tolerance capacitor is not appropriate. There are capacitors available with the same capacitance but varying amounts of tolerance. The capacitance value determines the physical size of the capacitor; as the capacitance rises, the size expands.
