Screw Terminal Aluminum Electrolytic Capacitors
PEH205, +125°C
Overview
Applications
KEMET's PEH205 Series of capacitors has a polarized
all-welded design, heavy duty screw terminals, extended
cathode construction, and safety vent. The sealing system
is designed for electrolyte leakage-free operation and a very
low gas-diffusion rate of electrolyte. Mechanical contact
between the winding and aluminium case allows excellent
heat transfer from the winding hot-spot to the ambient,
which means cooler operation and very high current ratings.
Typical applications for KEMET's PEH205 capacitor include
high temperature, high ripple current applications such as
welding equipment, industrial and automotive drives, and
high end professional power supplies.
Please note the PEH205 is housed in a bare can and does not feature
plastic insulation.
Benefits
• Long life, up to 8,000 hours at +125°C (VR , IR applied)
• High ripple current capability

Screw Terminal Aluminum Electrolytic Capacitors – PEH205, +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 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

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.

Screw Terminal Aluminum Electrolytic Capacitors – PEH205, +125°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.
Insulating Resistance
Please note the PEH205 is housed in a bare can and does not feature plastic insulation.
Clamp Fixing
Clips must be ordered separately.
Stud Fixing
Nylon cap nut must be ordered separately.
Maximum tightening torque:
M8 = 3 Nm
M12 = 8 Nm
Maximum chassis thickness = 5 mm
Screw Terminals
M5 x 10 according to DIN 41.248. Maximum tightening torque = 2.5 Nm. Must be ordered separately.
Recommended maximum connector thickness with delivered screw 4 mm. M6 thread upon request (65 and 75 mm

Screw Terminal Aluminum Electrolytic Capacitors – PEH205, +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.
Extended cathode
Anode foil
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 defined
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.
