DC FILTERING

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 mounting.

Furthermore, their performances allow to be

a very interesting

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.

θ_{hot spot}= θ_ambient+ (P_d+ P_t) x R_th

with P_d(Dielectric losses) = Q x tgδ₀

Q x tgδ₀[ ½ x C_nx (V_peakto _peak)²x f ] x tgδ₀

tgδ₀(tan delta)

For polypropylene, tgδ₀= 2 x 10^-4for frequencies

up to 1MHz and is independent of temperatures.

For polyester, tgδ₀values are shown in graph 4

on page 3.

PACKAGING MATERIAL

Self-extinguishing plastic case (V0 = in accordance with UL 94) ﬁlled

thermosetting resin.

P_t(Thermal losses) = R_sx (I_rms

)

Self-extinguishing thermosetting resin (V0 = in accordance with UL 94;

I3F2 = in accordance with NF F 16-101).

LIFETIME EXPECTANCY

One unique feature of this technology (as opposed to electrolytics) 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.

IEC 60384-2: Fixed metallized polyester

capacitors

Please note that this is theoretical, however, as the capacitor continues

to be functional even after this 2% decrease.
