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 fulll
these legislative requirements. The only material of concern in our products has been lead (Pb), which has been removed
from all designs to fulll the requirement of containing less than 0.1% of lead in any homogeneous material. KEMET will
closely follow any changes in legislation world wide 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.

Capacitance Change Within ±20% of the initial value
Dissipation Factor Does not exceed 200% of the specied value
Leakage Current Does not exceed specied value
Shelf Life
The capacitance, ESR and impedance of a capacitor will not change signicantly after extended storage periods, however the
leakage current will very slowly increase.
KEMET's E-series aluminum 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 E-series aluminum electrolytic capacitors is +5 to +35°C and less than 75% in
relative humidity.
KEMET's E-series aluminum electrolytic capacitors should not be stored in damp conditions such as water, saltwater spray or
oil spray.
KEMET's E-series aluminum 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 E-series aluminum electrolytic capacitors should not be stored under exposure to ozone, ultraviolet rays or
radiation.
If a capacitor has been stored for more than 18 months under these conditions and it shows increased leakage current,
then a treatment by voltage application is recommended.
Re-age (Reforming) Procedure
Apply the rated voltage to the capacitor at room temperature for a period of one hour, or until the leakage current has fallen
to a steady value below the specied limit. During re-aging a maximum charging current of twice the specied leakage
current or 5 mA (whichever is greater) is suggested.

Mounting Positions (Safety Vent)
In operation, electrolytic capacitors will always conduct a leakage current which causes electrolysis. The oxygen produced by
electrolysis will regenerate the dielectric layer but, at the same time, the hydrogen released may cause the internal pressure
of the capacitor to increase. The overpressure vent (safety vent) ensures that the gas can escape when the pressure reaches
a certain value. All mounting positions must allow the safety vent to work properly.
Installing
• A general principle is that lower-use temperatures result 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, particularly when high ripple current loads are applied. In any
case, the maximum category 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.
• 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.
• Verify that the space around the pressure relief device is according to the following guideline:
Case Diameter Space Around Safety Vent
≤ 16 mm > 2 mm
> 16 to ≤ 40 mm > 3 mm
> 40 mm > 5 mm
It is recommended that capacitors always be mounted with the safety device uppermost or in the upper part of the capacitor.
• If the capacitors are stored for a long time, the leakage current must be veri ed. If the leakage current is superior to the
value listed in this catalog, the capacitors must be reformed. In this case, they can be reformed by application of the rated
voltage through a series resistor approximately 1 kΩ for capacitors with VR ≤ 160 V (5 W resistor) and 10 kΩ for the other
rated voltages.
• In the case of capacitors connected in series, a suitable voltage sharing must be used.
In the case of balancing resistors, the approximate resistance value can be calculated as: R = 60/C
KEMET recommends, nevertheless, to ensure that the voltage across each capacitor does not exceed its rated voltage.

Application and Operation Guidelines
Electrical Ratings:
Capacitance (ESC)
Simplifi ed equivalent circuit diagram of an electrolytic capacitor
The capacitive component of the equivalent series circuit (Equivalent Series Capacitance ESC) is determined by applying an
alternate voltage of ≤ 0.5 V at a frequency of 120 or 100 Hz and 20°C (IEC 384-1, 384-4).
Temperature Dependence of the Capacitance
Capacitance of an electrolytic capacitor depends upon
temperature: with decreasing temperature the viscosity
of the electrolyte increases, thereby reducing its
conductivity.
Capacitance will decrease if temperature decreases.
Furthermore, temperature drifts cause armature
dilatation and, therefore, capacitance changes (up to 20%
depending on the series considered, from 0 to 80°C). This
phenomenon is more evident for electrolytic capacitors
than for other types.
Frequency Dependence of the Capacitance
Effective capacitance value is derived from the impedance
curve, as long as impedance is still in the range where the
capacitance component is dominant.

Co = Aluminum oxide capacitance (surface and thickness of the dielectric)
Re = Resistance of electrolyte and paper mixture (other resistances not depending on the frequency are not considered: tabs,

Impedance of an electrolytic capacitor is not a constant quantity that retains its value under all conditions; it changes
depending on frequency and temperature.

• Capacitive reactance predominates at low frequencies
• With increasing frequency, capacitive reactance Xc = 1/ωCo decreases until it reaches the order of magnitude of
electrolyte resistance Re(A)
• At even higher frequencies, resistance of the electrolyte predominates: Z = Re (A - B)
• When the capacitor’s resonance frequency is reached (ω0), capacitive and inductive reactance mutually cancel each other
1/ωCe = ωL, ω0 = C√1/LCe
• Above this frequency, inductive reactance of the winding and its terminals (XL = Z = ωL) becomes effective and leads to
an increase in impedance
Generally speaking, it can be estimated that Ce ≈ 0.01 Co.

Re is the most temperature-dependent component of an electrolytic capacitor equivalent circuit. Electrolyte resistivity will
decrease if temperature rises.
In order to obtain a low impedance value throughout the temperature range, Re must be as little as possible. However, Re
values that are too low indicate a very aggressive electrolyte, resulting in a shorter life of the electrolytic capacitor at high
temperatures. A compromise must be reached.
Leakage Current (LC)
Due to the aluminum oxide layer that serves as a dielectric, a small current will continue to fl ow even after a DC voltage has
been applied for long periods. This current is called leakage current.
A high leakage current fl ows after applying voltage to the capacitor then decreases in a few minutes, e.g., after prolonged
storage without any applied voltage. In the course of continuous operation, the leakage current will decrease and reach an
almost constant value.
After a voltage-free storage the oxide layer may deteriorate, especially at high temperature. Since there are no leakage
currents to transport oxygen ions to the anode, the oxide layer is not regenerated. The result is that a higher than normal
leakage current will fl ow when voltage is applied after prolonged storage.

Single-Ended Aluminum Electrolytic Capacitors – ESG Series, +105°C
Leakage Current (LC) cont’d
As the oxide layer is regenerated in use, the leakage current will
gradually decrease to its normal level.
The relationship between the leakage current and voltage applied
at constant temperature can be shown schematically as follows:
Where:
VF = Forming voltage
If this level is exceeded, a large quantity of heat and gas will be
generated and the capacitor could be damaged.
VR = Rated Voltage
This level represents the top of the linear part of the curve.
VS = Surge voltage
This lies between VR and VF. The capacitor can be subjected to VS for short periods only.
Electrolytic capacitors are subjected to a reforming process before acceptance testing. The purpose of this preconditioning
is to ensure that the same initial conditions are maintained when comparing different products.
Ripple Current (RC)
The maximum ripple current value depends on:
• Ambient temperature
• Surface area of the capacitor (heat dissipation area)
tan δ or ESR
• Frequency
The capacitor’s life depends on the thermal stress.
Frequency Dependence of the Ripple Current
ESR and, thus, the tan δ depend on the frequency of the applied voltage. This indicates that the allowed ripple current is also
a function of the frequency.
Temperature Dependence of the Ripple Current
The data sheet speci es maximum ripple current at the upper category temperature for each capacitor.
Expected Life Calculation
Expected life depends on operating temperature according
to the following formula: L = Lo x 2 (To-T)/10
Where:
L: Expected life
Lo: Load life at maximum permissible operating
temperature
T: Actual operating temperature
To: Maximum permissible operating temperature
This formula is applicable between 40°C and To.

Construction Data
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.
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 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.
Each capacitor is aged and tested before being sleeved and 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:
• Slitting of the anode foil after forming
• Attaching the tabs to the anode foil
• Minor mechanical damage caused during winding
A sample from each batch is taken by the quality department after
completion of the production process. This sample size is controlled
by the use of recognized sampling tables de ned in BS 6001.
The following tests are applied and may be varied at the request
of the customer. In this case the batch, or special procedure, will
determine the course of action.

• Leakage current
• Capacitance
• ESR
• Impedance
• Tan Delta
