Welcome to the World
of Electronic Components and Modules
Film capacitors are used in a wide range of designs in many sectors. AC film
capacitors are particularly suitable for the operation of asynchronous electric
motors and electric compressors. They are wound from two layers of metalized
film that form the electrodes. They are self-healing and have a particularly low
dissipation factor thanks to the use of polypropylene as the dielectric.
As motor run capacitors, they assure smooth and energy-saving operation of
the electric motors used in applications such as refrigerators, freezers, electric
compressors, washers, dryers, dishwashers, air-conditioning equipment, ventila-
tors, pumps, electric lawn mowers, electric doors and drives.
This brochure presents the MotorCap P2 aluminum can capacitors series
B32330/B32332 of EPCOS. The use of MotorCap capacitors increases the
energy efficiency of motors and compressors by up to 12 percent. They also
significantly improve the torque response of the motor (or compressor). This is
important for motors and compressors in continuous operation. MotorCap
capacitors are addressed particularly to manufacturers of air conditioners, wash-
ing machines, dryers, compressors for refrigerators and freezers, but also of
general electric motors for a variety of applications. MotorCapTM capacitors
conform to the highest safety standards (UL, VDE, TÜV, CQC).

Important Notes
The following applies to all products named in this
publication:
1. Some parts of this publication contain statements
about the suitability of our products for certain
areas of application. These statements are based on
our knowledge of typical requirements that are often
placed on our products in the areas of application con-
cerned. We nevertheless expressly point out that such
statements cannot be regarded as binding state-
ments about the suitability of our products for a
particular customer application. As a rule, EPCOS is
either unfamiliar with individual customer applications
or less familiar with them than the customers them-
selves. For these reasons, it is always ultimately in-
cumbent on the customer to check and decide
whether an EPCOS product with the properties de-
scribed in the product specification is suitable for use
in a particular customer application.
2. We also point out that in individual cases, a mal-
function of electronic components or failure
before the end of their usual service life cannot be
completely ruled out in the current state of
the art, even if they are operated as specified. In
customer applications requiring a very high level of
operational safety and especially in customer applica-
tions in which the malfunction or failure of an electronic
component could endanger human life or health (e.g.
in accident prevention or life-saving systems), it must
therefore be ensured by means of suitable design of
the customer application or other action taken by the
customer (e.g. installation of protective circuitry or
redundancy) that no injury or damage is sustained by
third parties in the event of malfunction or failure of an
electronic component.
3. The warnings, cautions and product-specific notes
must be observed.
4. In order to satisfy certain technical requirements, some
of the products described in this publication may
contain substances subject to restrictions in cer-
tain jurisdictions (e.g. because they are classed
as hazardous). Useful information on this will be
found in our Material Data Sheets on the Internet
(www.epcos.com/material). Should you have any more
detailed questions, please contact our sales offices.
5. We constantly strive to improve our products. Conse-
quently, the products described in this publication
may change from time to time. The same is true of
the corresponding product specifications. Please
check therefore to what extent product descriptions
and specifications contained in this publication are still
applicable before or when you place an order.
We also reserve the right to discontinue production
and delivery of products. Consequently, we cannot
guarantee that all products named in this publication
will always be available.
The aforementioned does not apply in the case of
individual agreements deviating from the foregoing for
customer-specific products.
6. Unless otherwise agreed in individual contracts, all
orders are subject to the current version of the
“General Terms of Delivery for Products and
Services in the Electrical Industry” published by
the German Electrical and Electronics Industry
Association (ZVEI).

MotorCap P2 Aluminum Can
Self-healing technology
An electric breakdown is possible as
the result of thermal or electric over-
load or at the end of service life. This
results in a small arc that evaporates
the metalization in the region of the
breakdown in a matter of microsec-
onds. The gas pressure caused at
this spot by the high temperature
blows the metal vapour away of the
breakdown region. This means that a
non-conducting isolation region free
of metalization is formed here. During
and after the breakdown the capaci-
tor is fully functional. The reduction in
capacitance caused by self-healing
is less than 100 pF, i.e. of an order
that can only be verified by a preci-
sion measuring instrument.

MotorCapTM P2 aluminum can protection via overpressure disconnection device
max. 16
Overpressure protection with a
break-action mechanism:
Electronic components do not
have unlimited life expectancies. This
applies to self-healing capacitors, too.
Motor run capacitors of the series
B32330/B32332 are conventionally
constructed as aluminum cans with
class P2 safety protection. They are
fitted with a disconnector that re-
sponds only to overpressure. Numer-
ous electric breakdowns over time or
as result of thermal or electric over-
load result in the formation of gas,
which can cause the pressure to rise
inside the capacitor case. This pro-
duces a change in length due to the
curvature of the lid or stretching of the
expansion bead. Expansion beyond a
certain degree will separate the inter-
nal wires and disconnect the capaci-
tor from the line. This disconnection
takes place at a defined position
(notch) after a total baffle expansion of
0.3 to 1.6 mm, depending on the size
of the capacitor.

General
Applications
The MotorCap P2 aluminum can
capacitor is simply plugged into the
auxiliary winding of the motor or
compressor and can remain perma-
nently connected there. MotorCap
P2 aluminum can capacitors are
designed for continuous operation.
The MotorCap P2 aluminum can
was optimized for use in the follow-
ing applications, but may be used
equally well for general drive motors.
Refrigerators and freezers
Electrical compressors
Washers and dryers
Dishwashers
Air conditioners
Requirements of IEC 60335-1
Domestic appliances are subject to
the IEC 60335-1 standard. If a motor
run capacitor is used in a domestic
appliance that is subject to this
standard, there may be additional
requirements on the capacitor.
These refer essentially to the
materials used as well as to the
creepage and clearance distances.
This approval in general is for the
complete capacitor assembly and
not for individual raw materials only.
The materials as well as the creep-
age and clearance distances se-
lected for the EPCOS MotorCap P2
aluminum can make it ideal for use in
domestic appliances.

General
Cautions and Warnings
The MotorCap P2 aluminum can should be operated
in line with its typical approved usage.
Handle the capacitor units carefully, as they may be
charged even after disconnection.
Observe the appropriate engineering practice.
The capacitor terminals, connected busbars and cables
as well as any other devices connected to them must be
regarded as live. The device is electrically charged.
Storage and operating conditions
Do not use or store capacitors in a corrosive atmosphere,
especially where chloride gas, sulfide gas, acids, alkalis,
salts or similar substances are present. In a dusty envi-
ronment, regular maintenance and cleaning, especially of
the terminals, is required to avoid formation of a conduc-
tive path between phases and/or phases and ground.
Ambient temperature
The capacitor must not be exposed to direct heat or fire.
The permissible range of minimum and maximum tem-
peratures is specified on the capacitor i.e.
25/70/21 = minimum permissible temperature: –25 °C,
max. permissible temperature: 70 °C.
25/85/21 = minimum permissible temperature: –25 °C,
max. permissible temperature: 85 °C.
Temperature is one of the main stress factors for
polypropylene type capacitors. It has a major influence
on their useful operating life. It should be noted that this
useful life is considerably shorter in the case of higher
temperature requirements. If the maximum permissible
temperature is exceeded, the safety device may become
inoperative.
VDo not expose the capacitor to a direct heat source!
Direct exposure or proximity to heat sources can cre-
ate hot spots on the capacitor much hotter than the
ambient temperature and can cause sudden internal
failures.
Operating voltage Vop
The capacitors have been designed for continuous oper-
ation at the rated voltage stated on the label. This voltage
may be exceeded only within the limits permitted by the
applicable standards at room temperature:
Vop Operating duration
1.1 · VR24 h/day
1.2 · VR5 min/day
1.3 · VR1 min/day
Installation
Mounting orientation
Motor-run capacitors may be mounted in any orientation.
However, the capacitor is preferentially mounted with its
terminals facing upwards.
VIn case of dents deeper than 0.5 mm, do not install
the capacitor.
Fixation
Motor-run capacitors must be installed in a cool and
well-ventilated place away from objects radiating heat.
The maximum torque of capacitors with an M8 bolt is
5 Nm. This bolt is used for grounding the aluminum case.
If the capacitor is fixed with a clamp, make sure this does
not block or disable its safety device.

Cautions and Warnings
Please read Important notes on page 4 and Cautions and warnings on page 13.
General
Connectors
In case of fast-on terminals, the female connectors must
be appropriate for the terminal. A good contact must be
ensured.
Do not solder cables directly onto the fast-on terminals.
The terminal may overheat, the capacitor may leak and
any safety device will not operate properly.
VIf the female connector becomes loose, the termi-
nal may overheat, the capacitor may leak and any safe-
ty device will not operate properly.
The hermetic seal of the capacitor is extremely important
for a long operating life and correct functioning of the
break-action mechanism of the overpressure discon-
nector. Do not damage the rubber seal and the soldering
at the tab connectors. The safety feature of the capacitor
may not function properly if the capacitor is short-circuit-
ed across the terminals. Sufficient precautions must be
taken when connecting the capacitor.
Harmonics
Harmonics are sinusoidal voltages and currents whose
frequencies are multiples of a 50 Hz or 60 Hz power sup-
ply frequency. They result from the operation of electrical
loads with non-linear voltage-current characteristics.
These loads are largely associated with modern electron-
ic devices such as converters, electrical drives, welding
machines and uninterruptible power supplies (UPS).
Harmonics may cause a higher than rated current to flow
through the capacitors, which may overheat and become
damaged. This may cause operational failures, bursting
and fire.
The maximum permissible current (incl. fundamental and
harmonic currents) specified in the technical data of the
relevant series must not be exceeded under any circum-
stances.
Overpressure disconnector
Electrical components do not have an unlimited operat-
ing life; this also applies to self-healing capacitors. All
capacitors of the B32330, B32331, B32332 and B32335
series are consequently fitted with a disconnector that
responds to overpressure. If numerous electrical break-
downs occur at the end of the capacitor’s operating life
or as a result of thermal or electrical overload, the forma-
tion of gas increases the pressure inside the capacitor
case.
This causes the expansion head to expand. If it does so
beyond a certain point, the internal wires will separate (tear-
off fuses) and disconnect the capacitor from the line
opening at a predefined position (notch) at an expansion
of 0.3 to 1.6 mm, depending on the capacitor size. This
safety mechanism is irreversible. Once the safety device
has operated, the capacitor will remain switched off.
Because the notch of the mechanical safety mechanism
is the weakest section in the connection, P2 aluminum
capacitors should be handled properly during transporta-
tion to avoid damaging the break-action mechanism.
Maintenance
There are no serviceable or repairable parts inside the
capacitor, so please refrain from opening it.
