6.2 The dissipation factor may be calculated from the
equivalent series resistance and capacitance values as
shown:
where:
DF = dissipation Factor in %
R = ESR in

f = frequency in Hz
At 120 Hz, the above equation becomes:

Note
Leakage current varies with applied voltage. See graph next
column for the appropriate adjustment factor

9.3 Capacitors are capable of withstanding life test at the
following conditions:
9.4 Following the life test, the capacitors shall be returned
