AC Voltage Load at the Mains
Anticipating possible
interfering pulses, DC voltage capacitors must not be
operated at the mains (line power), irrespective of the
rated AC voltage. For this purpose, use approved electromagnetic interference suppression
capacitors only.
Thermal Load in the Application
If a plastic film
capacitor is overstressed due to inappropriate usage
under AC voltage conditions, the temperature inside the
component may rise to an impermissibly high level. Thus,
the dielectric film may subsequently be damaged leading
to a short circuit or formation of smoke and even fire in
the capacitor. It may also happen if the capacitor is
overheated by an external heat source.
Shock and/or Vibration Load
for Larger Case Sizes
For increased shock and
vibration applications involving larger case sizes (i.e.,
PCM 22.5 mm lead spacing or greater), it is recommended
to fix capacitors in an appropriate way; or special lead
and tab terminations may be required respectively, to
minimize lead separation from the capacitor element or
the solder joint.
Processing
When processing plastic
film capacitors it is mandatory to observe the application
recommendations with regard to soldering and/or cleaning and drying
processes.
General Remarks
All data, range surveys
and application data correspond to the actual state of
the art and were elaborated as thoroughly and precisely
as possible. They are to be understood as general
information, and the right for amendments and
construction changes is reserved. Special customized
designs which deviate from our catalogue data,
irrespective of whether being based on factory standards,
specifications or related data, do not release the user
from his duty of care with regard to incoming goods
inspection and production monitoring. In case of the
components being purchased through second or third
suppliers we urgently ask to compare the technical
details with the data given by the manufacturer. In cases
of doubt we recommend use is made of our technical
support, since we do not take any responsibility for
damages caused by inappropriate use or processing of our
capacitors. |
