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 world wide 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 lead free (LF) or lead-free wires (LFW) on the
label.

Test Method & Performance
Conditions Load Life Test Shelf Life Test
Temperature 85°C 85°C
Test Duration 2,000 hours 1,000 hours
Ripple Current Maximumripplecurrentspecifiedat120Hz85°CNo ripple current applied
Voltage The sum of DC voltage and the peak AC voltage
must not exceed the rated voltage of the capacitor. No voltage applied
Performance The following specifications will be satisfied when the capacitor is restored to 20°C:
Capacitance Change Within ±20% of the initial value
Dissipation Factor Doesnotexceed200%ofthespecifiedvalue
Leakage Current Doesnotexceedspecifiedvalue
Shelf Life
Thecapacitance,ESRandimpedanceofacapacitorwillnotchangesignificantlyafterextendedstorageperiods,however,
the leakage current will very slowly increase.
KEMET's E 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 aluminum electrolytic capacitors is +5 to +35°C and less than 75%
in relative humidity. KEMET's E aluminum electrolytic capacitors should not be stored in damp conditions such as water,
saltwater spray or oil spray. KEMET's E 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 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specifiedlimit.Duringre-agingamaximumchargingcurrentoftwicethespecifiedleakage
current or 5 mA, whichever is greater, is suggested.

Single-Ended Aluminum Electrolytic Capacitors – ESK, +85°C
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, or 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
• As a general principle, 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 the 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verifi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 a 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.

Impedance of an electrolytic capacitor is not a constant quantity that retains its value under all conditions; it changes
depending on frequency and temperature.
Impedance as a function of frequency (sinusoidal waveform) for a certain temperature can be represented as follows:

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flow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,forexample,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 a 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.
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:
I
VRVFV
VS
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.

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defined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
