Press-Fit Aluminum Electrolytic Capacitors
ALF70, +85°C
Overview
Applications
The KEMET ALF70 Press-Fit capacitors eliminate the
need for solder, and therefore, the associated production
and quality issues. They are the next evolution of snapin capacitors, providing reliable electrical contact and
the same vibration performance as soldered snap-in
terminals. The ALF70 High CV Press-Fit capacitors offer
high performance and reliability in a wide range of case
sizes and voltage ratings (up to 630 V), featuring high
ripple currents and long-life performance. Volumetric
efficiency ensures the maximum capacitance capability in
a smaller size.
Typical applications for the ALF70 capacitor include
inverters, frequency converters, motor drives, motor
control, UPS systems, smoothing, energy storage,
alternative energy, charging stations, traction, demanding
power supplies (SMPS), welding, and HVAC.
Benefits

Press-Fit Aluminum Electrolytic Capacitors – ALF70, +85°C
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. Therefore, 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.
KEMET provides an online life calculator that can be used to predict hours of life for a given part number in specific
application conditions. This can be found at: https://elc.kemet.com.
End of Life Definition
Catastrophic failure: short circuit, open circuit or safety vent operation
Parametric Failure:
• Change in capacitance > ±15%
• Leakage current > initial specified limit
• ESR > 3X ESR Limit

Press-Fit Aluminum Electrolytic Capacitors – ALF70, +85°C
Environmental Compliance
All Part Numbers in this datasheet are Reach and RoHS compliant and Halogen-Free.
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 such as 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 worldwide 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.

Press-Fit Aluminum Electrolytic Capacitors – ALF70, +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 upright or inclined to a horizontal position. Special attention for the safety vent coverage,
which this ensures that internal gas generated can escape when the pressure reaches a certain value due to overstress or
catastrophic failure. All mounting positions must allow the safety vent to work properly.
Insulating Resistance
≥ 100 MΩ at 100 VDC across insulating sleeve.
Voltage Proof
≥ 3,500 VDC across insulating sleeve.
≥ 2,500 VAC across insulating sleeve.
Safety Vent
For diameters up to 40 mm, the safety vent for overpressure is featured on the base (opposing end to the terminals), and for
diameters 45 mm or higher, the safety vent is featured in the side of the can. This is a weakened area in the bottom of the
can that is designed to relieve build-up of internal pressure due to overstress or catastrophic failure.

Press-Fit Aluminum Electrolytic Capacitors – ALF70, +85°C
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 defi 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.
