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 kresistor.
