MotorCap P2 (S2) 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
appliances, ventilators, pumps, electric doors and drives.
This brochure presents the MotorCap P2 (S2) 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 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 conditioning systems, washing and
drying appliances, compressors for refrigerators and freezers, but also of general
electric motors 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 ar-
eas of application.
These statements are based on our
knowledge of typical requirements that are often placed
on our products in the areas of application concerned.
We nevertheless expressly point out
that such state-
ments cannot be regarded as binding statements
about the suitability of our products for a particular
customer application.
As a rule, EPCOS is either unfa-
miliar with individual customer applications or less famil-
iar with them than the customers themselves. For these
reasons, it is always ultimately incumbent on the cus-
tomer to check and decide whether an EPCOS product
with the properties described in the product specification
is suitable for use in a particular 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 re-
quiring a very high level of operational safety and espe-
cially 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 protec-
tive 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 publica-
tion may contain substances subject to restric-
tions in certain 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 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 indi-
vidual agreements deviating from the foregoing for cus-
tomer-specific products.
6. Unless otherwise agreed in individual contracts,
all or-
ders are subject to the current version of the “Gener-
al Terms of Delivery for Products and Services in the
Electrical Industry” published by the German Electri-
cal and Electronics Industry Association (ZVEI).
