WIRING ELECTROLYTIC CAPACITORS IN SERIES
What are some reasons to connect capacitors in series?
On the alternate halves of the AC cycles, one or the other of the foil strips acts as a blocking diode, preventing reverse current from damaging the electrolyte of the other one. Essentially, a 10 microfarad AC capacitor behaves like two 20 microfarad DC capacitors in inverse series." \$\endgroup\$ – endolith Jun 18 '10 at 22:10I have only seen it done to increase voltage.

Electronics Components: Capacitors in Parallel and Series
Connect capacitors in series. Here is an example for three capacitors whose values are 100 μF, 220 μF, and 470 μF: As you can see, the final result is 59 μF. Unless your name happens to be Spock, you probably don’t care about the answer being so precise, so you can safely round it to an even 60 μF.
