Medium Power Film Capacitors
FFLC
The FFLC series is specifically designed for DC filtering applications such as DC
link or resonant filters.
Large case sizes up to 35 liters and high specific energy up to 240J/l together with
safe and reliable Controlled Self Healing Technology make this series particularly
suitable for power converters in traction, drives and renewable energy areas.
FFLC uses polypropylene metallized segmented film and it is fully dry technology.
Standard designs proposed in this catalogue are covering a wide range of voltage
and capacitance values. In case of specific requirements about shape and
performances, feel free to contact your local AVX representative.
