In 1979, TPC (formerly LCC, then THOMSON-CSF PASSIVE
COMPONENTS) developed the CONTROLLED SELF-HEALING
technology for high power capacitors.
In 1988, TPC further evolved the CONTROLLED SELF-HEALING
technology for use in impregnated DC filtering capacitor (TRAFIM
series). This product range has been a great success with several
companies buying the TRAFIM license.
These capacitors made great advances over previous technologies
by combining the benefits of the Controlled Self-Healing process
and superior energy densities due to impregnation, making it one of
the most compact capacitors on the market for 1/2 CV2.
Today, TPC produces impregnated capacitors for high voltage
filtering, on the voltage range from 6kV to 32kV, using the same
technology as used in the TRAFIM series: “FIM technology”.
In the past, such filtering capacitors used foil electrodes. Any defect or
weak point in the film could provoke the catastrophic failure of the
capacitor involving a short-circuit with risk of explosion.
Now with the CONTROLLED SELF-HEALING, the capacitance is
divided into several millions elementary capacitances protected by
“fuse gates”. Weak points of the dielectric are insulated and the
capacitor continues functioning normally without any short circuit or
explosion.
The capacitor acts like a battery while working, it “consumes” a
certain amount of the capacitance through the gradual breakdown
of the individual capacitance “cells”. Over the life of the capacitor,
the capacitance gradually decreases. At the end of the capacitor’s
life, the nominal capacitance will decrease down to 2%.

FILFIM Controlled Self-Healing Technology
The FILFIM technology is based on the controlled self-
healing properties of the segmented metallized film. The
capacitance is divided into several million elementary capac-
itance cells protected by “fuse gates”.
The combined effect of metallization resistivity and segmen-
tation design induces two sensitivities of fuse effect. This can
be schematized (equivalent circuit) in the figure below.
Small weak point leading to low self-healing energy then
few mm2are insulated. Greater defect requiring higher self-healing energy. In that
case an elementary cell is insulated.
below is an example of a simple regeneration and an example of a cell insulation
The capacitor acts like a battery. While working, it consumes
a certain amount of the capacitance through the gradual
breakdown of the individual capacitance “cells”.
At the end of the capacitor life, the decrease of the initial
capacitance reaches 2%.

with required capacitance Cnand voltage Vn(provided
that VnVw) is recommended. Choosing Vn< Vwwill signif-
icantly decrease the expected lifetime (see the thermal
design chapter).

The highest Vw/Vnratio (= ρmax) for a lifetime of 100,000
hours can be derived from Curve 1.
ρmax =VWma /Vn= 1.06
so VWmax = 11,200 V (= 1.06 x 10,560)
(for θHS = 47.1°C and 100,000 hours)
According to Curve 2, theor etical lifetime at Vw= 10,560 V
and θHS = 47.1°C can be determined.
This gives a lifetime of 250,000 hours for this capacitor
under working conditions.

TERMINALS AND CONNECTIONS
Figure 1 shows drawings of the terminals offered.
The terminals type 1 is used on the range from 6-16 kV, the
type 2 from 16-32 kV.
Standard connection is via 2 terminals (see Figure 2).
It is possible to have a connection on the case as an option
with only one terminal.
MOUNTING
Vertical mounting is the preferred, and horizontal is
acceptable. Please contact AVX for up-side down mounting
configurations.
In order to enable air convection, it is necessary to maintain at
least 40mm between the large faces of adjacent capacitors.
BRACKETS
The capacitors are equipped with mounting brackets. They
are shown on Figure 2.
CASE CONNECTION OPTION
If only one terminal is preferred, one connection can be on
the case via 2 threaded screws which must be connected
externally.
Weight will be decr eased by approximately 0.5 kg for type [1]
equipped capacitors and by 1 kg for type [2].

IEC 1071 (2).
for Vw= 0.95× Vn(200,000 hours of lifetime expectancy)
θHS = 70°C

λ= 10-7 failures/hour
M.T.B.F. = 10,000,000 hours
Based on 10 years of tests results, the following relationship
has been established.
The failure rate λΒdepends on the hot spot temperature θHS
and the charge ratio ρ:
ρ = Vw/Vn
in failures/hour
GENERAL FAILURE RATE
λ= λΒ× πQ× πΒ× πE failures/hour
Where πQ πΒ and πE are factors found in the following tables.
MEAN TIME BETWEEN FAILURE (MTBF)
M.T.B.F. = 1/λhours
SURVIVAL FUNCTION
N = No. exp(-λt)
N is the number of pieces still working after t hours, No is the
number of pieces at the origin (t=0).

FILFIM Caution Features
HANDLING
When unpacking, it is important that no mechanical shocks
occur that might deform the cans and damage the output
connection.
The capacitors include, unless otherwise specified, one or
several gripping elements (mass screws, jack rings or other
hoisting devices); they should be exclusively handled by
means of these elements.
In no case should the electrical output terminals be
used to lift the capacitor.
The grounding wire should be kept in place until the
capacitor is mounted.
ASSEMBLY AND INSTALLATION
To check for the absence of excessive mechanical
stresses.
The mechanical stresses in assembly should remain com-
patible with the characteristics of the capacitor.
The method of mounting should not lead to the deformation
of the capacitor case.
Tightening torques are given below:
Output through threaded connections:
max = 25 N-m
Output on flats:
Tightening of the nut is realized by blocking the screw
head to avoid wrench on the terminal head.
Mechanical mounting
Considering the manufacturing tolerances for the cans
and the frames on which they are mounted, avoid:
4 anchoring points (or more) in the same plane.
2 or several separate parallel anchoring planes.
Whenever possible, priority should be given to anchoring by
flanging or binding with a damping element placed in
between.
Connections
They should not induce any force on the output terminals.
Flexible connections should be used (braided or thin metal).
The cross section should not be less than:
S = 0.2 x Imax where S (mm2) and Imax (A)
The skin effect which occurs at high frequencies, must also
be taken into account.
SAFETY
As stated, the TRAFIM technology is based on the controlled
self-healing property of the segmented film. This unique tech-
nology provides excellent safety: there is no risk of explosion
in case of defect throughout the life of the capacitor. This
explains why there is no need to equip these capacitors with
pressure switch.
Rapeseed oil is not explosive or flammable at normal condi-
tions, therefore capacitors can be transported without being
subjected to safety rules.
Rapeseed oil flash point is about 317°C and the polypropy-
lene flash point is near 300°C, so the melting certifies a tem-
perature of security above 300°C.
In case of fire above this temperature, it is recommended to
use dust or CO2. The use of water is contra-indicated. The
possible rejected products during fire are CO2, H2O, CO (in
case of non-complete combustion), hydrocarbons and some
others gazes. Carrying mask is required for protection.
CALORIFIC VALUE
We have established a simplified formula that gives the
calorific value of a standard FILFIM capacitor:
CV (MJ) = 0.0137W(mm) x H(mm) -0.0044 H(mm) +
0.2718 W(mm) + 15.46 + 6.2 x N x T
Where H is height and W is width, N is the number of terminal
(2 if normal, 1 in case of option) and T is code of terminal type.
EXAMPLE
DC FILTERING
For a standard capacitor (N = 2) of 107 µF / 10,600 V:
W = 185mm
H = 470mm
L = 350mm
then CV = 1280 MJ
as weight = 40 kg
then the calorific value per weight is
cv = 32 MJ/kg

FILFIM Environment Protection
OIL
The only impregnant used in FILFIM capacitors is rapeseed oil (otherwise known as Canola oil) and then is fully environmentally
compatible. It does not emit toxic or carcinogenic gases, nor is it harmful to soil, water or humans in the event of accidental
spillages. As a natural product derived from foodstuff, it is even edible.
Of all the vegetable oils, rapeseed oil has one of the best thermal stabilities and lowest acidity levels.
NON-TOXIC COMPOSITION
Our capacitors are free of:
Arsenic, Asbestos, Beryllium, Brominated flame retardants (PBB and PBDE), Cadmium, CFC, HCFC, Cobalt, Formaldehyde,
Halon, Isocyanatos, Mercury, Nickel PCB, PCT, Polyaromatic Hydrocarbons (PAH), Phtalates, PVC, PTFE and Thirams.
Lead is only found in soldering (for approximately 0.3% of the capacitor weight).
Free of SF6.
DESTROYING CAPACITORS
The destruction of the capacitors and leaking products are subject to the laws in force in each country.
In practice, today, please contact AVX for a list of companies who can take charge of the products to be destroyed.
