Medium Power Film Capacitors

FFB (RoHS Compliant)

The FFB series uses a non-impregnated 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.

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.

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

with P_d(Dielectric losses) = Q x tgδ₀

Q x tgδ₀⇒ [ ⁄

x C_nx (V_{peak 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.

P_t(Thermal losses) = R_sx (I_rms

)

PACKAGING MATERIAL

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

filled thermosetting resin.

WORKING TEMPERATURE

(according to the power to be dissipated) -55°C to +105°C

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 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.

STANDARDS

IEC 61071-1, IEC 61071-2: Power electronic capacitors

IEC 60384-16: Fixed metallized polypropylene

film dielectric DC capacitors

IEC 60384-16-1: Fixed metallized polypropylene

film dielectric DC capacitors

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

continues to be functional even after this 2% decrease.
