Case Polarity
Due to the presence of electrolyte in the capacitor, the aluminum can and stud mounting will essentially be at the same
polarity as the negative terminal. We recommend that the stud and can be insulated (see accessories for insulating nuts).
Terminations
Aluminum inserts with M5 threads as standard, maximum torque 2NM. Optional M6 threaded inserts have a maximum
torque 4NM. Maximum torque for stud mounting M8:4NM and M12:8NM.

Screw Terminal Aluminum Electrolytic Capacitors – ALS30/31 Series, +85°C
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 products are particularly stable and allow a shelf life in excess of three
years at 40°C. See sectional specication under each product series for specic data.
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.
Reliability
The reliability of a component can be dened as the probability that it will perform satisfactorily under a given set of
conditions for a given length of time.
In practice, it is impossible to predict with absolute certainty how any individual component will perform; thus, we must
utilize probability theory. It is also necessary to clearly dene the level of stress involved (e.g. operating voltage, ripple
current, temperature and time). Finally, the meaning of satisfactory performance must be dened by specifying a set of
conditions which determine the end of life of the component.
Reliability as a function of time, R(t), is normally expressed as: R(t)=e-λt
where R(t) is the probability that the component will perform satisfactorily for time t, and λ is the failure rate.
Failure Rate
The failure rate is the number of components failing per unit time. The failure rate of most electronic components follows
the characteristic pattern:
• Early failures are removed during the manufacturing process.
• The operational life is characterized by a constant failure rate.
• The wear out period is characterized by a rapidly increasing failure rate.
The failures in time (FIT) are given with a 60% condence level for the various type codes. By convention, FIT is expressed as
1 x 10-9 failures per hour. Failure rate is also expressed as a percentage of failures per 1,000 hours.
e.g., 100 FIT = 1 x 10-7 failures per hour = 0.01%/1,000 hours
End of Life Denition
Catastrophic Failure: short circuit, open circuit or safety vent operation
Parametric Failure:
• Change in capacitance > ±10%
• Leakage current > specied limit
• ESR > 2 x initial ESR value

The mean time between failures (MTBF) is simply the inverse of the failure rate.

Failure Rate
Time
The failure rate is derived from our periodic test results. The failure rate (λR) is, therefore, only given at test temperature for
life tests. An estimation is also given at 40°C. The expected failure rate for this capacitor range is based on our periodic test
results for capacitors with structural similarity. Failure rate is frequently quoted in FIT (Failures In Time) where 1 FIT = 1 x 10-9
failures per hour. Failure rate per hour includes both catastrophic and parametric failures.
Ta Failure Rate per Hour
85°C 250 FIT
40°C 12 FIT
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.

Screw Terminal Aluminum Electrolytic Capacitors – ALS30/31 Series, +85°C
Mechanical Data
Polarity and Reversed Voltage
Aluminium Electrolytic capacitors manufactured for use in DC applications contain an anode foil and a cathode foil. As such,
they are polarized devices and must be connected with the +ve to the anode foil and the -ve to the cathode foil. If this were
to be reversed then the electrolytic process that took place in forming the oxide layer on the anode would be recreated in
trying to form an oxide layer on the cathode. In forming the cathode foil in this way, heat would be generated and gas given
off within the capacitor, usually leading to catastrophic failure.
The cathode foil already possesses a thin stabilized oxide layer. This thin oxide layer is equivalent to a forming voltage
of approximately 2 V. As a result, the capacitor can withstand a voltage reversal of up to 2 V for short periods. Above this
voltage, the formation process will commence. Aluminium Electrolytic capacitors can also be manufactured for use in
intermittent AC applications by using two anode foils in place of one anode and one cathode.
Mounting Position
The capacitor can be mounted in any position as long as the safety vent can operate. It is possible for some electrolyte to be
expelled. As this is a conducting liquid, suitable precautions should be initiated by the system designer to avoid secondary
short circuits.
The capacitors are designed to be mounted in free air and are not suitable for submersion in liquid.
Low Inductance Version
A low inductance version of the ALS30/31 capacitors can be designed upon request, typically reducing the inductance by up
to 40% of the standard capacitor's inductance. It is available in 77 & 90 mm diameters.
Insulating Resistance
≥ 100 MΩ at 100 VDC across insulating sleeve. UL recognized sleeving is available for custom parts in this range, upon
request.
(UL No. E358957)
Voltage Proof
≥ 2,500 VDC across insulating sleeve
Safety Vent
A safety vent for overpressure is featured on terminal deck. This is in the form of a rubber plug designed to relieve build-up
of internal pressure due to overstress or catastrophic failure.

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.
