FFLI-HV Datasheet

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.

LIFETIME EXPECTANCY VS HOT SPOT TEMPERATURE AND VOLTAGE
HOW TO CHOOSE THE RIGHT CAPACITOR
The capacitor lifetime depends on the working voltage and the hot spot temperature.
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

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 tg0 with

- Q(reactive power) =
I rms
for a sinusoidal waveform
C
θHS
-4
- tg0 = 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

SURVIVAL FUNCTION
N = N0 x exp(-t)
N is the number of pieces still working after t hours.
N0 is the number of pieces at the origin (t = 0)
FAILURE MODE
Main failure mode due to AVX’s Controlled Self-Healing Technology is only losses of capacitance.
Thanks to Controlled Self-Healing solution to interrupt self-healing process in order to prevent avalanche effect
due to polypropylene molecular cracking producing gas and potential explosion in confined box for none
Controlled Self-Healing capacitors.

MECHANICAL MOUNTING
Capacitors enclosure presents a M12 x 16 bolt in order to fix the capacitor. Over height (H) more than 1.5 x D
(diameter of tube), we recommend to clamp (constraint < 35daN), just below the plastic cover, the capacitor in
order to limit oscillations in case of potential Shock&Vibration stress.
