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.

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

film dielectric DC capacitors

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.

film dielectric DC capacitors

Assessment level E

IEC 60384-17: Fixed metallized polypropylene

film dielectric AC and pulse

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

continues to be functional even after this 2% decrease.
