Axial Aluminum Electrolytic Capacitors
PEG124, +105°C and +125°C
Overview
Applications
KEMET's PEG124 is an electrolytic capacitor with very longlife and outstanding electrical performance. The device has
a polarized all-welded design, tinned copper wire leads, a
negative pole connected to the case, and plastic insulation.
Long-life and very high reliability are achieved by dimensioning
of the capacitor, careful selection of materials/methods,
and discipline in quality control allowing operation up to
+125°C/+105°C.
KEMET's PEG124 is a high performance axial electrolytic
capacitor. Typical applications include smoothing, coupling/
decoupling and energy storage in telecommunication,
power supply system, data processing, process control
and measuring, where long life and high reliability are of
paramount importance.
The PEG124 winding is housed in a cylindrical aluminum can,
with a high purity aluminum lid and high quality rubber gasket.
The sealing system is designed for electrolyte leakage-free
operation and a very low gas-diffusion rate of electrolyte.
The low ESR is the result of a low resistive electrolyte/paper
system and an all-welded design.

Axial Aluminum Electrolytic Capacitors – PEG124, +105°C and +125°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 ten years
at 40°C. See sectional specification under each product series for specific data.
Failure Rate
Estimated field failure rate: ≤ 1.0 ppm (failures per year/produced number of capacitors per year).
The expected failure rate for this capacitor range is based on field experience for capacitors with structural similarity.
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.

Axial Aluminum Electrolytic Capacitors – PEG124, +105°C and +125°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 winding is assembled to the capacitor Al-can and to
the Al-lid. The can is filled with electrolyte and the winding
is impregnated during a vacuum treatment. The capacitor
is 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 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 carried out at elevated temperature and is accomplished by
applying voltage to the device while carefully controlling the
supply current. The process takes between 2 and 20 hours,
depending on voltage rating.
Damage to the oxide layer can occur due to a variety of
reasons:
• Slitting of the anode foil after forming
• Attaching the tabs to the anode foil
• Minor mechanical damage caused during winding
The following tests are applied for each individual capacitor.
Electrical:
• Leakage current
• Capacitance
• ESR
• Tan Delta
Mechanical/Visual:
• Pull strength test of wire terminals
• Print detail
• Box labels
• Packaging, including packed quantity

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 specifically disclaims – any warranty concerning suitability for a specific 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 specifically 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 filled
with filling 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, inflicted, 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.
