Medium Power Film Capacitors FFLI 1500V to 3000Vdc (RoHS Compliant) The FFLI series is specifically designed for DC filtering applications such as DC link. This high voltage range offers solutions for voltage from 1500V up to 3000V. The Controlled Self Healing Technology, essential to ensure a safe and reliable behaviour, is achieved using a wet solution with both polypropylene metallized film and oil (without free oil). 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 70°C 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- From the tables, select a capacitor with required capacitance Cn and voltage Un. Calculate the maximum ripple voltage allowed for the selected cap : Urmax = 0.2Un If Ur > Urmax, select a capacitor with higher rated voltage Make sure Irms application < Irms table Copy out : serial resistance (Rs) : see table of values thermal resistance Rth Medium Power Film Capacitors FFLI 1500V to 3000Vdc (RoHS Compliant) 2- Hot spot temperature calculation Rth : thermal resistance between hot spot and ambient air Total losses are calculated as follow: Pt = Pj + Pd Joule losses : Pj = Rs x Irms² Rth Dielectric losses : Pd = Q x tg0 with 2 - Q(reactive power) = I rms for a sinusoidal waveform C θHS -4 - tg0 = 2 x 10 (dielectric losses of polypropylene) Hot spot temperature will be: HS = amb + (Pj + Pd) x Rth HS absolute maximum is 85°C If temperature is higher than 85°C, come back to #1 and start again with another selection. 3- Refer to the curve and deduce the lifetime vs Uw / Un ratio LIFETIME EXPECTANCY VS HOT SPOT TEMPERATURE AND VOLTAGE eg: rated voltage 2000V working voltage 2200V = 1.1 lifetime 80 000hours @ 60°C hot spot temperature Please, find a calculation form at the end of the catalogue θAMB Medium Power Film Capacitors FFLI 1500V to 3000Vdc (RoHS Compliant) MTBF CALCULATION The failure rate B depends on hot spot temperature HS and charge ratio . = U w / Un B 3 10 2.75 1 e 30 3.2 HS 273 358 10 9 in failures/hour GENERAL FAILURE RATE = B x Q x B x E failures/hour Qualification Q, B and E see following tables Qualification factor Q Product qualified on IEC61071 and internal qualification Product qualified on IEC61071 Product answering on another norm Product without qualification Environment On ground (good conditions) On ground (fixed materials) On ground (on board) On ship On plane Environment Favorable Unfavourable 1 2 5 15 Environment factor E 1 2 4 9 15 Environment factor B 1 5 MEAN TIME BETWEEN FAILURE (MTBF) MTBF = 1 / hours SURVIVAL FUNCTION N = N0 x exp(-t) N is the number of pieces still working after t hours.
