DC Working Voltage: The DC working voltage is the
maximum operating voltage for continuous duty at the
rated temperature.
3.
Surge Voltage: The surge DC rating is the maximum
voltage to which the capacitors may be subjected
under any conditions, including transients and peak
ripple at the highest line voltage.
3.1
Surge Voltage Test: Capacitors shall withstand the
surge voltage applied in series with a 33 ohm ± 5%
resistor at the rate of one-half minute on, one-half
minute off, at + 85°C, for 1000 successive test cycles.

PERFORMANCE CHARACTERISTICS
and the leakage current shall meet the initial require-
ments; the capacitance shall not have changed
more than ± 10%.
4.
Capacitance Tolerance: The capacitance of all
capacitors shall be within the specified tolerance
limits of the normal rating.
4.1
Capacitance measurements shall be made by means
of polarized capacitance bridge. The polarizing
voltage shall be of such magnitude that there shall be
no reversal of polarity due to the AC component.
The maximum voltage applied to capacitors during
measurement shall be 2 volts rms at 120 Hz at
+ 25°C. If the AC voltage applied is less than one-
half volt rms, no DC bias is required. Accuracy of the
bridge shall be within ± 2%.
5.
Capacitance Change With Temperature: The
capacitance change with temperature shall not
exceed the following percentage of the capacitance
measured at + 25°C:
6.
Dissipation Factor: The dissipation factor,
determined from the expression 2πfRC, shall not
exceed values listed in the Standard Ratings Table.
6.1
Measurements shall be made by the bridge method
at, or referred to, a frequency of 120 Hz and a
temperature of + 25°C.
