For capacitors whose capacitance value exceeds 1000 F, the value
of DF(%) is increased 2% for every additional 1000 F.
The maximum ripple current at 105gC and 120 Hz for SEK capacitors
is shown in the Standard Rating Table. Maximum ripple current may
be adjusted by the multipliers in the following tables.
