What are the advantages and thermal
capabilities of polyester film for use in the manufacture of
capacitors and ballasts?
The outstanding physical characteristics of polyester film,
along with its availability in a thickness range starting
below one micron and exceeding 100 microns, allow a variety
of possibilities for the design of dielectric capacitors.
• High dielectric constant
•
High breakdown strength
•
Mechanical strength
•
Thermomechanical stability
•
Temperature resistance
•
Long life
•
Good self-healing properties when metallized
Polyester film capacitors are used in the following
fields.
• Automotive
•
Telecommunication
•
IT hardware
•
Consumer electronics
•
Lighting and electronic ballast
The actual melting point of PET
polyester film is about 242ºC. Although it will begin
to lose mechanical strength at high temperatures, polyester
film can withstand short t e rm thermal excursions if
protected
from oxidation.
Shrinkage and embrittlement due to
thermal aging of polyester film
at high temperatures can be addressed through equipment
design. In a tightly
wound unit, the polyester film will be held
inplace, greatly reducing shrinkage. Likewise, a tightly
wound, well-varnished
coil will significantly reduce mechanical stress and vibration
that could affect the polyester film
as it ages.
