The capacitance, ESR, and impedance of a capacitor will not change signicantly 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 specication under each product series for specic 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 specied limit. During re-aging, a maximum charging current of twice the specied leakage
current or 5 mA (whichever is greater) is suggested.
Reliability
The reliability of a component can be dened 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 dene the level of stress involved (e.g., operating voltage, ripple
current, temperature, and time.) Finally, the meaning of satisfactory performance must be dened 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 specic
application conditions. This can be found at: https://elc.kemet.com.

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 fulll these legislative requirements. The only material of
concern in our products has been lead (Pb), which has been removed from all designs to fulll 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.
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.
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.

All product speci cations, statements, information and data (collectively, the “Information”) in this datasheet are subject to change. The customer is responsible for
checking and verifying the extent to which the Information contained in this publication is applicable to an order at the time the order is placed. All Information given
herein is believed to be accurate and reliable, but it is presented without guarantee, warranty, or responsibility of any kind, expressed or implied.
Statements of suitability for certain applications are based on KEMET Electronics Corporation’s (“KEMET”) knowledge of typical operating conditions for such
applications, but are not intended to constitute – and KEMET speci cally disclaims – any warranty concerning suitability for a speci c customer application or use.
The Information is intended for use only by customers who have the requisite experience and capability to determine the correct products for their application. Any
technical advice inferred from this Information or otherwise provided by KEMET with reference to the use of KEMET’s products is given gratis, and KEMET assumes
no obligation or liability for the advice given or results obtained.
Although KEMET designs and manufactures its products to the most stringent quality and safety standards, given the current state of the art, isolated component
failures may still occur. Accordingly, customer applications which require a high degree of reliability or safety should employ suitable designs or other safeguards
(such as installation of protective circuitry or redundancies) in order to ensure that the failure of an electrical component does not result in a risk of personal injury
or property damage.
Although all product–related warnings, cautions and notes must be observed, the customer should not assume that all safety measures are indicated or that other
measures may not be required.
KEMET requires its products to be packaged and shipped on pallets. This is because KEMET’s products are speci cally designed to be packed onto pallets during
shipment. If for any reason, the products are removed from pallets by the shipping party and shipped to the end customer, then additional external protection is
required. In this instance, an external box with two carton layers and an upwards orientation sticker must be used by the shipping party, with the empty space lled
with lling material, and afterwards sealing the box. If this packing and packaging guideline is not followed by the shipping party, the shipping party, and not KEMET,
will be held responsible for any packaging, packing and/or product damages upon delivery of the products to the end customer. KEMET hereby disclaims any liability
for damages to the products or otherwise that have been, or threaten to be, infl icted, result from or are in any way related to the packaging, packing or damage by the
shipping party in contravention of the packing and packaging guidelines herein.
