Capcom Capacitors
Capacitors for Motor Run Applications
Genteq metallized film capacitors are unsurpassed in terms of size, weight, performance, and
reliability for AC applications. Capcom over 60 year of capacitor manufacturing experience to the
product lines described in this publication. These capacitors represent the best in product design for
long-term reliability and safe operation. Capcom´s materials, product, and process development
work continue to provide capacitor users with outstanding total value.
The GEM III Motor Run Capacitors are widely used with permanent split phase capacitor motors for
the more efficient use of electricity. These motors are used in heating and cooling equipment,
appliances, business machines, office equipment, and a wide variety of light commercial and
industrial equipment.
GEM III Construction
Capcom´s GEM III capacitors are manufactured with
high-grade metallized polypropylene film. This film is in
the range of 5 to 10 microns thick, depending on the
application, voltage, and conditions. The metallized
electrode is several hundred angstroms thick.
The film is wound into capacitor rolls on high-speed,
precision machines. The winding is extremely tight so
that there is not enough space between the layers for
corona (localized partial electrical discharges) to occur.
The rolls are sprayed on both ends with metal to make
the connection to the extremely thin edges of the
metallized electrodes. This process is critical to the
quality and performance of the capacitors.
The rolls are assembled in metal cases, Capcom´s
proprietary dielectric liquid is introduced under vacuum,
and the capacitors are sealed. They are then subjected
to 100% electrical testing for capacitance, dissipation
factor, and high potential electrical withstand, both
terminal-to-terminal and terminal-to-case.
