Shelf Life and Re-Ageing
• 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 +35ºC 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.
The capacitance, ESR and impedance of a capacitor will not change significantly after extended storage periods, however the
leakage current will very slowly increase.
If a capacitor is stored for a long period of time, the leakage current must be verified. If the leakage current is superior to the
value listed in this catalog, the capacitors must be reformed.
Re-age (Reforming) 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 fulfill
these legislative requirements. The only material of concern in our products has been lead (Pb), which has been removed
from all designs to fulfill 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.
Because of customer requirements, there may appear additional markings such as LF = Lead-free, or LFW = Lead-free wires
on the label.

Single-Ended Conductive Polymer Aluminum Solid Electrolytic Capacitors
A750 Series, 105°C
Installing
Conductive polymer aluminum solid electrolytic capacitors are prone to a change in leakage current due to thermal
stress during soldering. The leakage current may increase after soldering or reflow soldering. Therefore, do not use these
capacitors in circuits sensitive to leakage current.
• Do not use in a high resistance, high voltage circuit.
• Do not use in a coupling circuit.
• Do not use in a time constant circuit.
• Do not use in a circuits that are significantly affected by leakage current.
A general principle is that lower temperature operation results in a longer, useful life of the capacitor. For this reason, it
should be ensured that electrolytic capacitors are placed away from heat-emitting components. Adequate space should be
allowed between components for cooling air to circulate, especially when high ripple current loads are applied. In any case,
the maximum rated temperature must not be exceeded.
• Do not deform the case of capacitors or use capacitors with a deformed case.
• Verify that the connections of the capacitors are able to insert on the board without excessive mechanical force.
Excessive force during insertion, as well as after soldering may cause terminal damage and affect the electrical
performance.
• Ensure electrical insulation between the capacitor case, negative terminal, positive terminal and PCB.
• If the capacitors require mounting through additional means, the recommended mounting accessories shall be used.
• Verify the correct polarization of the capacitor on the board.
KEMET recommends, to ensure that the voltage across each capacitor does not exceed its rated voltage.
Temperature Stability Characteristics
Stable characteristics in a very low temperature range allows for less circuits in the design.
Due to a solid polymer electrolyte, conductive polymer electrolytic capacitors feature higher conductivity. This results
in a lower ESR which, coupled with high capacitance allows an aluminum polymer capacitor to replace several standard
electrolytic capacitors, reducing the number of components and maximizing board space.
The ESR of polymer capacitors is nearly constant within its operating temperature range, while the ESR of a standard
electrolytic capacitor noticeably changes with temperature.

Single-Ended Conductive Polymer Aluminum Solid Electrolytic Capacitors

Construction Data
Anode foil
Cathode foil
Foil tabs
The manufacturing process begins with the anode foil being
electrochemically etched to increase the surface area and
then ‘formed’ to produce the aluminum oxide layer. Both the
anode and cathode foils are then interleaved with absorbent
paper and wound into a cylinder. During the winding process,
aluminum tabs are attached to each foil to provide the
electrical contact.
Tissues
The deck, complete with terminals, is attached to the tabs
and then folded down to rest on top of the winding. The
complete winding is impregnated with a conductive polymer
electrolyte before being housed in a suitable container, usually
an aluminum can, and sealed. Throughout the process, all
materials inside the housing must be maintained at the
highest purity and be compatible with the electrolyte.

Winding
Weꢀding
Fꢀrꢁing
Each capacitor is aged and tested before being packed.
The purpose of aging is to repair any damage in the oxide
layer and thus reduce the leakage current to a very low level.
Aging is normally carried out at the rated temperature of the
capacitor and is accomplished by applying voltage to the
device while carefully controlling the supply current. The
process may take several hours to complete. Damage to the
oxide layer can occur due to variety of reasons:

ꢀꢁeaning
• Slitting of the anode foil after forming
• Attaching the tabs to the anode foil
• Minor mechanical damage caused during winding

Product Safety
THESE NOTES SHOULD BE READ IN CONJUNCTION WITH THE PRODUCT DATA SHEET. FAILURE TO OBSERVE THE RATINGS
AND THE INFORMATION ON THIS SHEET MAY RESULT IN A SAFETY HAZARD.
Warning
When potential lethal voltages e.g. 30 VAC (RMS) or 60 VDC are applied to the terminals of this product, the use of a
hazard warning label is recommended.
1. Electrolyte
Conductive polymer aluminum solid electrolytic capacitors contain polymers (electrolytes) which can be hazardous.
1.1 Safety Precautions
In the event of gas venting, avoid contact and inhalation. Wash the affected area with hot water. Use rubber gloves to avoid
skin contact. Any contact with the eyes should be liberally irrigated with water and medical advice sought.
2. Intrinsic Properties
2.1 Operating
DC capacitors are polar devices and will operate safely only if correctly connected. Reversing the connections will result
in high leakage currents which could subsequently cause short circuit failure and possibly explosion and fire. Correctly
polarized operation may result in the above failure modes if:
• The surge voltage is exceeded
• The ambient temperature is too high
• Excessive ripple currents are applied
2.2 Non-Operating
Excessive torque or soldering heat may affect the performance of the capacitor or damage the sealing. Electric shock may
result if capacitors are not discharged.
3. Disposal
Aluminum electrolytic capacitors are consignable waste under the Special Waste Regulations 1996 (Statutory Instrument
1996 No 972), which complies with the EC Hazardous Waste Directive – Directive 91/689/EEC. The electrolyte should
therefore be treated as a hazardous waste and advice should be sought from the local office of the Environmental Agency
regarding its disposal.
Due to the construction of an aluminum electrolytic capacitors, high temperature incineration may cause the component to
explode due to build-up of internal pressure. In addition, incineration may also cause the emission of noxious fumes.
KEMET strongly recommends that if there are any doubts regarding the disposal of conductive polymer aluminum solid
electrolytic capacitors, that advice be sought from the local regulating authority.
In addition, KEMET would like to request that users of aluminum electrolytic capacitors respect the needs of the environment
and, wherever possible, recover as much of the materials as possible, i.e. aluminum.

Product Safety cont'd
4. Unsafe Use
Most failures are of a passive nature and do not represent a safety hazard. A hazard may, however, arise if this failure causes
a dangerous malfunction of the equipment in which the capacitor is employed. Circuits should be designed to fail safe under
the normal modes of failure.
The usual failure mode is an increase in leakage current or short circuit. Other possible modes are decrease of capacitance,
increase in dissipation factor (and impedance) or an open circuit. Capacitors should be used in a well-ventilated enclosure or
cabinet.
5. Mounting
Care should be taken when mounting by clamp, that any safety vent in the can is not covered.
6. Fumigation
In many countries throughout the world it is now common practice to fumigate shipments of products in order to control
insect infestation, particularly when wooden packaging is used. Currently, methyl bromide is widely used as a fumigant,
which can penetrate cardboard packing and polymer bags and, therefore, come into direct contact with equipment or
components contained within.
If aluminum electrolytic capacitors become exposed to methyl bromide then corrosion may occur, depending upon the
concentration and exposure time to the chemical.
This failure mode can affect all types of KEMET aluminum electrolytic capacitors. Methyl bromide can penetrate the seals of
aluminum electrolytic capacitors and cause internal corrosion of the anode connection, resulting in the component becoming
open circuit. The rate of corrosion will depend upon the level of exposure to methyl bromide as well as the subsequent
operating conditions, such as voltage and temperature. It may take months or, in some cases, several years before the
component becomes open circuit.
7. Dielectric Absorption
A phenomenon known as dielectric absorption can cause aluminum electrolytic capacitors to recharge themselves. The
phenomenon is well known but impossible to predict with any great accuracy, so potentially any electrolytic product could be
affected. Thus, a capacitor that has been charged and then completely discharged will appear to recharge itself if left open
circuit; this will manifest itself as a small voltage across the terminals of the capacitor. Generally, the voltages seen are less
than 20 VDC. However, higher voltages have on occasion been reported.
In order to avoid any problems caused by this voltage, KEMET recommends that capacitors be discharged before connecting
to the terminals.
