Aluminum Electrolytic Capacitors
1 General Specifications
Capacitance
Nominal capacitance is specified at 120Hz
frequency and 20°C temperature. Unless
specified otherwise, standard capacitance
tolerance is ±20% of the nominal value.
Working Voltage
The maximum allowable sum of continuous DC
voltage plus peak ripple voltage which can be
applied to the capacitor.
Surge Voltage
The maximum transient voltage level allowed
for short periods of time without sustaining
permanent damage to the capacitor. Values are
listed in the standard product ratings.
Leakage Current
Shelf Life
Duration: 1000 hours
Ambient Temp.: Maximum specified
operating temperature
Applied Voltage: None
Post test requirements at +20°C:
Same as Endurance Test requirements above.
Measurements are to be performed after
applying DC working voltage for 30 minutes.
2 Life Expectancy
Panasonic capacitors have a specified life at a
maximum temperature and ripple current.
Typical life can be considerably longer based on
actual life test results performed by the factory.
This data can be provided to help the designer
estimate expected life. This information is given
with a 60% confidence level.
Capacitor life at lower temperatures follows
"The Doubling 10°C Rule" where life is doubled
for each 10°C reduction in operating
temperature. The following equation is useful for
determining the life of a capacitor in the
application;

CV
(µA) maximum after 5 minutes of
applying rated voltage. Capacitance is the
nominal value in µF, voltage in VDC.
Ripple Current
The standard product tables list ripple current
allowable limits at specified maximum operating
temperatures.
Correction factors for other temperatures and
frequencies are listed in the general sections for
the general product type.
Endurance (Life) Test
Duration: Specified hours of life
Ambient Temp.: Maximum specified
operating temperature
Applied Voltage: DC voltage with
maximum specified ripple

of the
applied DC voltage plus
the peak ripple voltage
should not exceed rated
working voltage)

It is recommended that the ripple current heat
rise be limited to 15°C at lower ambient
temperatures as higher temperature rises may
reduce operating life.

Life Cycle of an Aluminum Electrolytic Capacitor
3 Circuit Design Considerations
Operating Temperature and Frequency
Aluminum electrolytic capacitor electrical
characteristics are normally specified at a
temperature of 20°C and a frequency of 120Hz.
Electrical parameters are temperature and
frequency dependent as follows;
(1) Effects of operating temperature
At higher temperatures, capacitance and
leakage current increase while ESR
decreases.
At lower temperatures, capacitance and
leakage current will decrease while ESR
increases.
(2) Effects of frequency
Capacitance, impedance, and ESR will
decrease as frequency increases.
At lower frequencies, ripple current
generated temperature will rise due to
increasing ESR.
Reverse Voltage
DC capacitors have polarity which must be
verified before insertion.
Avoid use in circuits with changing or uncertain
polarity.
Ensure that allowable ripple currents super-
imposed on low DC bias voltages do not cause
reverse voltage conditions.
Normal DC leakage current variations among
capacitors can cause voltage differences. The
use of voltage dividing sharing resistors with
consideration to leakage currents can
compensate for voltage imbalances.
Electrical Precautions
Transient recovery voltage may be generated in
the capacitor due to dielectric absorption.
Typical voltage levels are less than 10% of the
rated capacitor voltage. If required, this voltage
can be discharged with a resistor.
The aluminum case of the capacitor has an
indeterminate resistance to the cathode
terminal. The vinyl sleeve on the capacitor is for
marking and identification purposes and is not
meant to electrically isolate the capacitor.
When designing circuits, consider worst
case capacitor failure modes such as open
or short circuits.
The effects of hot, electrically conductive,
combustible, electrolyte liquid or vapor
escaping from the safety vent should also
be considered.
4 Capacitor Mounting Considerations
Circuit Board Design
Avoid wiring pattern runs which pass between
the mounted capacitor and the circuit board.
When dipping into a solder bath, excessive
solder may collect under the capacitor by
capillary action and short circuit the anode and
cathode terminals.
