LEAKAGE AS A FUNCTION OF VOLTAGE
AND TEMPERATURE
For example, percent dissipation factor of a 30 µF, 6 V
capacitor, which has a maximum ESR of 3.4 Ω at
+ 25 °C and 120 Hz, would be calculated as shown:
Leakage Current: Measurements shall be made at
the applicable rated working voltage at + 25 °C ± 5 °C
through application of a steady source of power, such
as a regulated power supply. The total resistance in
series with each capacitor shall be between 1000 Ω
and 10 000 Ω. The voltage shall be applied to the
capacitor for 5 minutes before making the leakage
current measurement.
The maximum leakage current for any capacitor shall
not exceed the value in microamperes listed in the
Standard and Extended Ratings Table for each
capacitor.
Note: leakage current varies with applied voltage. See graph
below for the appropriate adjustment factor.
Low Temperature Impedance: The impedance of
any capacitor at - 55 °C at 120 Hz, shall not exceed the
values given in the Standard and Extended Ratings
tables.

Life Test: Capacitors are capable of withstanding a
2000 h life test at a temperature of + 85 °C or + 125 °C
at the applicable rated DC working voltage.
High Frequency Vibration: Capacitors shall with
stand vibration from 10 Hz to 2000 Hz at 20 g when
tested.
Lead Pull Test: Capacitors shall withstand a lead
tensile stress of 3 pounds (13.2 N) for 30 s, applied
axially.
Marking: Capacitors shall be marked with Sprague
and/or the Sprague trademark 2, the Sprague type
(138D);
tolerance shall be coded, using the list shown in How
to Order); rated DC working voltage at + 85 °C; the
standard EIA date code of manufacture.
Ripple Current: All capacitors will withstand rms
ripple currents as listed for each capacitor.
The rms ripple current rating is independent of
temperature
limitations:
current must be multiplied by the factors shown:
shall not exceed the DC working voltage of the
capacitor.
applied DC voltage shall not allow a voltage reversal.
Customary cleaning solvents used in the electronics
industry at present will not affect Type 138D
capacitors. However, the use of ultrasonic cleaning
techniques
circumstances.
Apparent Capacitance: Note that in timing circuit
applications, the circuit designer must take into
account two important variables which affect any
electrolytic capacitor. These are the internal leakage
resistance
absorption, which will depend on the elapsed time
since the capacitor was last energized. In applications
where electrolytic capacitors are subjected to DC
energy, or in effect, extremely low frequencies, the
value of the apparent capacitance will be somewhat
higher than that which is measured at 120 Hz.
No Reverse Voltage: The application of reverse
voltage to these capacitors will cause internal damage.
The resulting damage will lead to immediate or
delayed failure of the unit. This will take the form of a
catastrophic short circuit with possible expulsion of the
electrolyte.
