Radial Crown Aluminum Electrolytic Capacitors
PEH227, +125°C & +150°C
Overview
Applications
These electrolytic capacitors contain a radial crown,
which allows them to be mounted in a standing position.
They feature Ultra-High CV with an outstanding electrical
performance and high energy storage capability, a
polarized, all-welded design, tinned copper wire leads,
and a negative pole connected to the case. The winding
is housed in a cylindrical aluminium can with a high purity
aluminium lid and a high quality rubber gasket. Low ESR
is a result of a low resistive electrolyte/paper system
and an all-welded design. Thanks to its mechanical
robustness, these capacitors are suitable for use in mobile
and aircraft installations, with operation up to +150°C.
KEMET automotive grade capacitors meet the demanding
Automotive Electronics Council's AEC–Q200 qualification
requirements.
The KEMET PEH227 is a new generation of Ultra-High
CV radial crown electrolytic capacitors. It is designed for
automotive applications with extremely high demands.

Radial Crown Aluminum Electrolytic Capacitors – PEH227, +125°C & +150°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 for specific data.
Failure Rate
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.
As Per PEG Equivalents
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.

Radial Crown Aluminum Electrolytic Capacitors – PEH227, +125°C & +150°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

(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

KEMET requires its products to be packaged and shipped on pallets. This is because KEMET’s products are specifi 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 fi lled
with fi 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,
