PERFORMANCE CHARACTERISTICS
1.
Operating Temperature: capacitors are designed to
operate over the temperature range of -55 °C to
+85 °C with no derating.
6.
Dissipation Factor: the dissipation factor,
determined from the expression 2πfCR, shall not
exceed values listed in the Standard Ratings table.
1.1
Capacitors may be operated up to +125 °C with
voltage derating to two-thirds the +85 °C rating.
6.1
7.
Measurements shall be made by the bridge method
at, or referred to, a frequency of 1000 Hz and a
temperature of +25 °C.
+85 °C RATING
+125 °C RATING
Leakage Current: capacitors shall be stabilized at
the rated temperature for 30 min. Rated voltage shall
be applied to capacitors for 5 min using a steady
source of power (such as a regulated power supply)
with 1000 Ω 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.

DC Working Voltage: the DC working voltage is the
maximum operating voltage for continuous duty at
the rated temperature.

Surge Voltage Test: capacitors shall withstand the
surge voltage applied in series with a 33 Ω 5 %
resistor at the rate of 1.5 min on, 1.5 min off at
+85 °C, for 1000 successive test cycles.

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 VRMS at 1000 Hz at +25 °C.
If the AC voltage applied is less than 0.5 VRMS, no DC
bias is required. Measurement accuracy of the
bridge shall be within 2 %.
