In fact I really meant series, since it makes the electrolytes non-polarized
(if you connect eg. the + - poles together and - - poles to the circuit). It
halves the capacity, but it is still much cheaper to buy two 47 uF
capacitors than eg. one 20 uF polystyrene. However, the electrical
properties are not nearly as good as with 'normal' capacitors.
