DC FILTERING
30 ■ JUNE 2015
Medium Power Film Capacitors
FFLI 800V to 1400Vdc (RoHS Compliant)
The FFLI series is specifically designed for DC filtering applications such as DC link.
This range offers solutions for voltage from 800V up to 1400V.
The Controlled Self Healing Technology, essential to ensure a safe and
reliable behaviour, is achieved using a fully dry solution with polypropylene
metallized and segmented film. 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, please feel
free to contact your local AVX representative.
