Surface Mount Solid Polymer Aluminum Capacitors
A768 125°C
Overview
Applications
KEMET’s Surface Mount Solid Polymer Aluminum
Capacitors offer longer life and greater stability across a
wide range of temperatures. This highly conductive solid
polymer electrolyte eliminates the risk of drying out and,
due to its low ESR properties, is able to withstand higher
ripple currents during normal operation. This series is
ideally suited for automotive and industrial applications.
This series is AEC-Q200 qualified for voltages up to 63
V and upon request for 80 V. Anti-Vibration version is
available for 10 mm diameter. See Part Number system to
order AEC-Q200 qualified parts. If CV/Size is not available
please contact your local Sales Representative for more
information.
Typical applications include long life LED drivers,
professional power amplifiers, industrial power supplies,
DC/DC converters, voltage regulators, and decoupling.
For voltages ≤ 63 V, this series is used for automotive
powertrain.

Environmental Compliance
All Part Numbers in this datasheet are Reach and RoHS compliant, and Halogen-Free.
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 make 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.

Shelf Life & Re-Ageing
Shelf Life
Solderability is 12 months
The capacitance, ESR and impedance of a capacitor will not change significantly after extended storage periods, however the
leakage current will slowly increase.
• This series should not be stored in high temperatures or where there is a high level of humidity.
• The suitable storage condition is +5 to +35°C and less than 75% in relative humidity.
• Do not store in damp conditions such as water, saltwater spray or oil spray.
• Do not store in an environment full of hazardous gas (hydrogen sulphide, sulphurous acid gas, nitrous acid, chlorine gas,
ammonium, etc.)
•Do not store under exposure to ozone, ultraviolet rays or radiation.
If a capacitor has been stored for more than 12 months under these conditions and it shows increased leakage current,
then a treatment by voltage application is recommended. The Capacitor should be soldered within 7 days after unpack.
MSL Rating 2A
Re-age Procedure
Apply the rated DC voltage to the capacitor at 125°C for a period of 120 minutes through a 1 kΩ series resistor.

Surface Mount Solid Polymer Aluminum Capacitors
A768 125°C
Installing
Solid Polymer Aluminum 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, verify the suitability for use in circuits sensitive
to 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
table characteristics in a very low temperature range allows for less circuits in the design.
Due to a solid polymer electrolyte, Solid Polymer Aluminum 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.

Stability of ESR across Frequency Range
Due to a solid polymer electrolyte, the ESR curve of a solid polymer aluminum capacitor, is lower and more stable than that
of a standard electrolytic capacitor.

High Resistance to Ripple Current
As a result of a lower ESR, solid polymer aluminum capacitors are able to withstand higher ripple currents during
normal operation.

Re-Flow Soldering
The soldering conditions should be within the specified conditions below:
• Do not dip the capacitors body into the melted solder.
• Flux should only be applied to the capacitors terminals.
• Vapour heat transfer systems are not recommended. The system should be thermal, such as infra-red radiation or hot
blast.
• Observe the soldering conditions as shown below.
• Do not exceed these limits and avoid repeated reflowing.
