DC FILTERING 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. PACKAGING MATERIAL Aluminium cylindrical case filled polyurethane resin.

Our caps are designed to meet 100000 hours lifetime at rated voltage and 65C hot spot temperature. In accordance with operating conditions, please calculate the hot spot temperature and deduce from this calculation if the obtained lifetime can suit the application. 1.
