2 Storage Life (continued)
3 Operation Life Expectancy
Design and specifi cations are subject to change without notice. Ask factory for technical specifi cations before purchase and/or use.
Storage may require reforming of the capacitor
to reduce leakage current below the specified
limit. This can be accomplished by applying
rated voltage in series with a 1000
a time period of 30 ~ 60 minutes.
Panasonic capacitors have a specified life at a
maximum
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.
Voltage derating also improves life expectancy
and reliability. The following equations are useful
for determining the life of a capacitor in the
application;
The capacitor is acceptable for use if the
capacitor leakage current is within the original
specified limit or the capacitor is reformed to
within the original specified limit.
Storage in high humidity conditions could cause
oxidation of the terminal plating which could
adversely affect solderability.

4 Circuit Design Considerations
Life Cycle of an Aluminum Electrolytic Capacitor
Use of the ripple current temperature multipliers
listed for each product series may limit life to the
value originally specified for maximum operating
temperature.
It is recommended that the ripple current heat
rise be limited to 15°C at lower ambient
temperatures to accomplish the maximum
operating life in the application.
End of life is defined by the occurrence of one of
the following;
Operating Temperature and Frequency
Aluminum electrolytic capacitor electrical
characteristics are normally specified at a
temperature of 20°C and a frequency of 120Hz.
NOTE: Electrical measurements are taken after
Capacitance change exceeds ±20% of the
initial measured value.
Dissipation Factor exceeds 200% of the initial
specified value.
Leakage Current exceeds the initial specified
value.
