Medium Power Film Capacitors
FFB (RoHS Compliant)
The FFB series uses a metallized polypropylene or polyester
dielectric with the controlled self-healing process, specially
treated to have a very high dielectric strength in operating
conditions up to 105°C.
This is a dry solution for polypropylene and dry or wet for
polyester.
The FFB has been designed for printed circuit board mount-
ing. Furthermore, their performances allow to be a very inter-
esting alternative to electrolytic technology because they
can withstand much higher levels of surge voltage.
APPLICATIONS
The FFB capacitor is particularly designed for DC filtering,
low reactive power.
HOT SPOT CALCULATION
See Hot Spot Temperature, page 3.
θhot spot = θambient + (Pd+ Pt) x Rth
with Pd(Dielectric losses) = Q x tgδ0
Q x tgδ0⇒ [ 1⁄2x Cnx (Vpeak to peak)2x f ] x tgδ0
tgδ0(tan delta)
For polypropylene, tgδ0 = 2 x 10-4 for frequencies
up to 1MHz and is independent of temperatures.
For polyester, tgδ0 values are shown in graph 4
on page 3.
Pt(Thermal losses) = Rsx (Irms)2
where Cnin Farad Irms in Ampere f in Hertz

Rth in °C/W
WORKING TEMPERATURE
(according to the power to be dissipated) -55°C to +105°C
LIFETIME EXPECTANCY
One unique feature of this technology (as opposed to elec-
trolytics) is how the capacitor reacts at the end of its lifetime.
Unlike aluminum, electrolytics film capacitors do not have a
catastrophic failure mode. Film capacitors simply experience
a parametric loss of capacitance of about 2%, with no risk of
short circuit.
Please note that this is theoretical, however, as the capacitor
continues to be functional even after this 2% decrease.
