Axial Aluminum Electrolytic Capacitors
PEG225 Series, +125ºC and +150ºC
Overview
KEMET's PEG225 is an electrolytic capacitor with outstanding
electrical performance. The device has a polarized all-welded
design, tinned copper wire leads, and a negative pole connected
to the case. The PEG225 winding is housed in a cylindrical
aluminum can with a high purity aluminum lid and high
quality rubber gasket. Low ESR is the result of a low resistive
electrolyte/paper system and an all-welded design. Thanks to its
mechanical robustness, the PEG225 is suitable for use in mobile
and aircraft installations with operation up to +150°C.
Applications
KEMET's PEG225 is a new generation of high performance axial
electrolytic capacitors. It is designed for automotive applications
with extremely high demands.

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., 100FIT = 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

Estimated field failure rate: ≤ 0.15 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
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.
