Single-Ended Conductive Polymer Aluminum Solid Electrolytic Capacitors
A759 125°C
Shelf Life & Re-Ageing
The capacitance, ESR and impedance of a capacitor will not change signicantly after extended storage periods, however,
the leakage current will very slowly increase.
• KEMET's conductive polymer aluminum solid electrolytic capacitors should not be stored in high temperatures or where
there is a high level of humidity.
• The suitable storage condition for KEMET's conductive polymer aluminum solid electrolytic capacitors is +5° to +35°C
and less than 75% in relative humidity.
• KEMET's conductive polymer aluminum solid electrolytic capacitors should not be stored in damp conditions such as
water, saltwater spray or oil spray.
• KEMET's conductive polymer aluminum solid electrolytic capacitors should not be stored in an environment full of
hazardous gas (hydrogen sulphide, sulphurous acid gas, nitrous acid, chlorine gas, ammonium, etc.)
• KEMET's conductive polymer aluminum solid electrolytic capacitors should not be stored under exposure to ozone,
ultraviolet rays or radiation.
If a capacitor has been stored for more than 24 months under these conditions and it shows increased leakage current, then
a treatment by voltage application is recommended.
Re-Age Procedure
Apply the rated DC voltage to the capacitor at 105°C for a period of 120 minutes through a 1 kΩ series resistor.
Environmental Compliance
As an environmentally conscious company, KEMET is working continuously with improvements concerning the environmental
effects of both our capacitors and their production. In Europe (RoHS Directive) and in some other geographical areas like
China, legislation has been put in place to prevent the use of some hazardous materials, such as lead (Pb), in electronic
equipment. All products in this catalog are produced to help our customers' obligations to guarantee their products and fulll
these legislative requirements. The only material of concern in our products has been lead (Pb), which has been removed
from all designs to fulll the requirement of containing less than 0.1% of lead in any homogeneous material. KEMET will
closely follow any changes in legislation worldwide and makes any necessary changes in its products, whenever needed.
Some customer segments such as medical, military and automotive electronics may still require the use of lead in electrode
coatings. To clarify the situation and distinguish products from each other, a special symbol is used on the packaging labels
for RoHS compatible capacitors.
Due to customer requirements, there may appear additional markings such as LF = Lead-free or LFW = Lead-free wires on the
label.
