Medium Power Film Capacitors
FFLC
DC FILTERING
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.

HOW TO CHOSE 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.

Voltage
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 resistances Rth1 and Rth2 (depending on cooling conditions)

2. Hot spot temperature calculation
Total losses are calculated as follow: Pt=Pj+Pd
Joule losses: Pj = Rs x Irms²
Dielectric losses: Pd = Q x tgδ0 with
• Q(reactive power) = Irms2 for a sinusoidal waveform

• tgδ0 = 2 x 10 (dielectric losses of polypropylene)
Hot spot temperature will be:
␪HS = ␪amb + (Pj + Pd) x (Rth1 + Rth2)
␪HS absolute maximum is 85°C
If temperature is higher than 85°C, come back to #1 and start again
with another selection.

SURVIVAL FUNCTION
N = N0 x exp (-λt)
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.
