Snap-In Aluminum Electrolytic Capacitors  
ALC42 Series, 105ºC  
Overview  
Applications  
KEMET's ALC42 Series of capacitors is a high CV snap-in  
version of the ALC40 Series range. Both feature the same high  
ripple currents and long-life characteristics as the ALC10 Series  
but can operate at higher temperatures.  
KEMET's ALC42 Series of capacitors is designed for applications  
where high reliability and compact sizes are important, such as  
switch mode power supplies (SMPS) and frequency converters.  
Benefits  
• Compact size  
• 2,000 hours at +105°C (VR, IR applied)  
• Excellent surge voltage capability  
• Optimized designs available upon request

Snap-In Aluminum Electrolytic Capacitors – ALC42 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 products are particularly stable and allow a shelf life in excess of three years at 40°C. See  
sectional specification under each product series for specific 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 specified limit. During re-aging a maximum charging current of twice the specified leakage current or 5 mA (whichever  
is greater) is suggested.  
Reliability  
The reliability of a component can be defined 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 define the level of stress involved (e.g. operating voltage, ripple current, temperature and time).  
Finally, the meaning of satisfactory performance must be defined 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% confidence 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 Definition  
Catastrophic Failure: short circuit, open circuit or safety vent operation  
Parametric Failure:  
• Change in capacitance > ±10%  
• Leakage current > specified limit  
• ESR > 2 x initial ESR value

MTBF  
The mean time between failures (MTBF) is simply the inverse of the failure rate.  
MTBF= 1/λ

operational life  
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.

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.

Snap-In Aluminum Electrolytic Capacitors – ALC42 Series, +105ºC  
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 upright or inclined to a horizontal position.  
Insulating Resistance  
≥ 100 MΩ at 100 VDC across insulating sleeve.  
Voltage Proof  
≥ 2,500 VDC across insulating sleeve.  
Safety Vent  
A safety vent for overpressure is featured on either the base (opposing end to the terminals) or the side of the can. This appears in the  
form of a grooved section on the surface of the can, which is a weakened area and designed to relieve build-up of internal pressure due  
to overstress or catastrophic failure.

Snap-In Aluminum Electrolytic Capacitors – ALC42 Series, +105ºC  
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.  
Extended cathode  
Anode foil  
Foil tabs  
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.  
Tissues  
Cathode foil  
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.  
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.
