DESCRIPTION
The FLC21 series have been developed especially
for capacitance discharge operation. The main
applications are: fuel ignitor, fuel or gas heater,
gas range, cook top, barbecue, water heater,
HVAC, portable ignitor, insect killers.
It uses a high performance planar diffused
technology device adapted to high temperature in
rugged environmental conditions.
The typical supply of the FLC21 fire lighter circuit is
a DC battery or the AC mains.
Th: Thyristor for the switching operation.
Z: Zener diode to set the igniting threshold voltage.
D: Diode for the reverse conduction.
R: 2 kΩ resistor.

RS RESISTANCE CALCULATION
The Rs resistance allows, in addition with the
capacitance C, to adjust the spark frequency and
to limit the current supplied by the mains. This
resistance allows the thyristor triggering in any
requested cases. In worst cases, the system must
fire when the a.c. line voltage is minimum while the
breakdown voltage VBO and the current IBO of the
FLC are maximum.
The maximum Rs value is equal to:
Rs max = (VAC min. 2 ) − [VBO max .(1 + α T .( Tamb − 25 ))]

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.
