MotorCap P2 Aluminum Can
AC Film Capacitors for Motor Run Applications
For film capacitors, the metalized technology is applied. An extremely thin metal film is
deposited in a high vacuum onto the low-loss polypropylene film. Then two layers of
metalized film are wound to form the electrodes. The impulse resistance is possible
due to the so-called self-healing effect. By using polypropylene as the dielectric, the
capacitors have a particularly low dissipation factor.
AC film capacitors are usable for general sine-wave applications as filters, inverters,
UPS devices etc., but are also particularly suitable for the operation of asynchronous
electric motors and electric compressors. As motor run capacitors, they assure
smooth and energy-saving operation of electric motors used in applications such as
refrigerators, freezers, electric compressors, washers, dryers, air-conditioning appli-
ances, ventilators, pumps, electric doors and drives.
This brochure presents the MotorCap P2 aluminum can capacitors series B32330/
B32332/32333/32335 of EPCOS. The use of MotorCap capacitors increases the
energy efficiency of motors and compressors by up to 12 percent. They also signifi-
cantly improve the torque response of the motor (or compressor). This is important for
motors and compressors in continuous operation. MotorCap capacitors are ad-
dressed particularly to manufacturers of air conditioning systems, washing and drying
appliances, compressors for refrigerators and freezers, but also of general electric mo-
tors for a variety of applications. MotorCap capacitors comply to high 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 ap-
plication.
These statements are based on our knowledge
of typical requirements that are often placed on our prod-
ucts in the areas of application concerned. We neverthe-
less expressly point out
that such statements cannot be
regarded as binding statements about the suitability
of our products for a particular customer application.
As a rule, EPCOS is either unfamiliar with individual cus-
tomer applications or less familiar with them than the
customers themselves. For these reasons, it is always ul-
timately incumbent on the customer to check and decide
whether an EPCOS product with the properties described
in the product specification is suitable for use in a partic-
ular customer application.
2. We also point out that
in individual cases, a malfunc-
tion 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 requir-
ing a very high level of operational safety and especially in
customer applications 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 electron-
ic 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 certain jurisdic-
tions (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 con-
tact 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 speci-
fications 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 “Gen-
eral Terms of Delivery for Products and Services in
the Electrical Industry” published by the German
Electrical and Electronics Industry Association (ZVEI).
