Medium Power Film Capacitors

FAI (RoHS Compliant)

TUNING

The FAI series uses metallized polypropylene dielectric

specifically designed for very high reactive power.

The FAI's special design gives to this series a very low level

of stray inductance.

APPLICATIONS

These capacitors have been designed principally for:

low and medium frequency applications

(10 kHz to 500 kHz)

MAXIMUM WORKING TEMPERATURE

(HOT SPOT)

+85°C: Hot spot temperature must be calculated as function

of power dissipation.

HOT SPOT (THERMAL) CALCULATION

See Hot Spot Temperature page 3.

Theoretical life time vs hot spot temperature

1000000

You can calculate the maximum operating (hot spot) tem-

perature of this capacitor in the following manner:

Polypropylene has a constant loss factor (tgδ₀) of 2x10^-4

100000

10000

1000

irrespective of temperature and frequency (up to 1 MHz).

The loss factor of the capacitor is made up of the sum of

two components. The first represents electrical losses

(tgδ₀= 2.10^-4) and the second represents Joule effect in the

connection and foils: Rs.C.2πF.

Hot spot temperature (∞C)

For all applications, the temperature in the hot spot capacitor

must be lower than 85°C.
