DESCRIPTION
The FLC10 series have been developed espe-
cially for high power capacitance discharge opera-
tion. The main applications are gas lighter or
ignitor such as :
cookers / gas boilers / gas hobs...
It uses a high performance planar diffused tech-
nology adapted to high temperature and rugged
environmental conditions.

The couple Rs/C can be chosen with the previous
curve. Keep in mind the Rs maximum limit for
which the system would not work when the AC
mains is minimum. The next curve shows the be-
havior with Rs=15kΩ and C=1µF.
