capacitor uF values question
Yes, you can put a bunch of 220uF caps in PARALLEL to get a higher value of capacitance.  You also have to pay attention to the voltage rating of the caps, polarity, and potentially things like the ESR, dielectric, and self resonant frequency, depending on the application.
Some ceramic capacitors in particular will derate with applied DC bias, so it's important to understand not only the value of capacitance, but the characteristics of the cap as well.
So if chosen correctly according to the requirements of the application, it's possible.
