Operating Temperature: Capacitors are designed to
operate over the temperature range - 55°C to + 85°C.
Capacitors may be operated to + 125°C with
voltage derating to two-thirds the + 85°C rating.
DC Working Voltage: The DC working voltage is the
maximum operating voltage for continuous duty at the
rated temperature.
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.
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.
Following the surge voltage test, the dissipation
factor and the leakage current shall meet the initial
requirements; the capacitance shall not have changed
more than ± 10%.
Capacitance Tolerance: The capacitance of all
capacitors shall be within the specified tolerance
limits of the normal rating.
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%.
Capacitance Change With Temperature: The
capacitance change with temperature shall not exceed
the following percentage of the capacitance measured
at + 25°C:

TYPICAL LEAKAGE CURRENT FACTOR RANGE
Dissipation Factor: The dissipation factor,
determined from the expression 2πfRC, shall not
exceed values listed in the Standard Ratings Table.
Measurements shall be made by the bridge method
at, or referred to, a frequency of 120 Hz and a
temperature of + 25°C.
Leakage Current: Capacitors shall be stabilized at
the rated temperature for 30 minutes. Rated voltage
shall be applied to capacitors for 5 minutes using a
steady source of power (such as a regulated power
supply) with 1000 ohm resistor connected in series
with the capacitor under test to limit the charging
current. Leakage current shall then be measured.
Note that the leakage current varies with
temperature and applied voltage. See graph below
for the appropriate adjustment factor.
