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 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 Aluminum Electrolytic Capacitors – ESU Series, +105ºC

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-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 +35ºC 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 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 – ESU Series, +105ºC

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

> 5 mm

> 40 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 veriﬁed. 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 V_R≤ 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)

Simpliﬁed 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

Capacitance Change vs. Temperature

(typical value)

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.

Impedance of an electrolytic capacitor results from a circuit formed by the following individual equivalent series

components:

ꢂ_e

ꢃ

C_o

C_e

C_o= Aluminum oxide capacitance (surface and thickness of the dielectric)

R_e= Resistance of electrolyte and paper mixture (other resistances not depending on the frequency are not considered: tabs,

plates, etc.)

C_e= 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/ωC_odecreases until it reaches the order of magnitude of

electrolyte resistance R_e(A)

• At even higher frequencies, resistance of the electrolyte predominates: Z = R_e(A - B)

• When the capacitor’s resonance frequency is reached (ω₀), capacitive and inductive reactance mutually cancel each other

1/ωC_e= 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 C_e≈ 0.01 C_o.

R_eis 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, R_emust be as little as possible. However, R_e

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 ﬂows 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 ﬂow when voltage is applied after prolonged storage.

Single-Ended Aluminum Electrolytic Capacitors – ESU Series, +105ºC

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:

V_F= Forming voltage

If this level is exceeded, a large quantity of heat and gas will be

generated and the capacitor could be damaged.

V_R= Rated Voltage

ꢁ_ꢂ

ꢁ_S

ꢁ_ꢃ

ꢁ

This level represents the top of the linear part of the curve.

V_S= Surge voltage

This lies between V_Rand V_F. The capacitor can be subjected to V_Sfor 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 speciﬁes maximum ripple current at the upper category temperature for each capacitor.

Expected Life Calculation

Expected life depends on operating temperature according

Single-Ended Aluminum Electrolytic Capacitors – ESU Series, +105ºC

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.

ꢀꢁiꢂ ꢃaꢄꢅ

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.

ꢀiꢁꢁꢂeꢁ

ꢀaꢁꢂꢃde ꢄꢃiꢅ

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.

Aging

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.
