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.

Radial Aluminum Electrolytic Capacitors – ESK Series, +85ºC
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.
• 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 mm 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)
Capacitance is measured by applying an alternate voltage of ≤ 0.5 V at a frequency of 120 or 100 Hz and 20°C.
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.

Radial Aluminum Electrolytic Capacitors – ESK Series, +85ºC
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.
C =
1
C = Capacitance (F)
2π fZ
f = Frequency (Hz)
Z = Impedance (Ω)
Dissipation Factor tan δ (DF)
Dissipation Factor tan δ is the ratio between the active and reactive power for a sinusoidal waveform voltage. It can be thought of as a
measurement of the gap between an actual and ideal capacitor.
reactive

Tan δ is measured with the same set-up used for the series capacitance ESC.
tan δ = ω x ESC x ESR where:
ESC = Equivalent Series Capacitance
ESR = Equivalent Series Resistance
Equivalent Series Inductance (ESL)
Self inductance or Equivalent Series Inductance results from the terminal conguration and internal design of the capacitor.

Radial Aluminum Electrolytic Capacitors – ESK Series, +85ºC
Equivalent Series Resistance (ESR)
Equivalent Series Resistance is the resistive component of the equivalent series circuit. ESR value depends on frequency and
temperature and is related to the tan δ by the following equation:
ESR = Equivalent Series Resistance (Ω)
ESR =
tan δ
tan δ = Dissipation Factor
2πf ESC
ESC = Equivalent Series Capacitance (F)
f = Frequency (Hz)
Tolerance limits of the rated capacitance must be taken into account when calculating this value.
Impedance (Z)
Impedance of an electrolytic capacitor results from a circuit formed by the following individual equivalent series components:
C
o
R
e
L
C
e
CoReL
Ce
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, plates,
etc.)
Ce = Electrolyte soaked paper capacitance
L = Inductive reactance of the capacitor winding and terminals
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:

• 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.
Impedance as a function of frequency (sinusoidal waveform) for different temperature values can be represented as follows (typical
values):

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 ow even after a DC voltage has been
applied for long periods. This current is called leakage current.
A high leakage current 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 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.

Radial Aluminum Electrolytic Capacitors – ESK Series, +85ºC
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.
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.

Radial Aluminum Electrolytic Capacitors – ESK Series, +85ºC
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.

Radial Aluminum Electrolytic Capacitors – ESK Series, +85ºC
Construction
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.
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.
