output capacitance needed is calculated as:
Cout = -2---Ï-----Ã-----4---5---1--Ã-1----54---6---0-----Ã-----4---0-- = 22.1μF

The voltage rating on the capacitor needs to account for the
operation of the device before it hits the overvoltage protection
threshold. This is typically 105% of nominal value, which is
483 V. With the ripple voltage factored in, 22 μF of
capacitance rated at 500 V would suffice for this application.
