TUNING
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

You can calculate the maximum operating (hot spot) temperature
of this capacitor in the following manner:

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