DESCRIPTION
The FLC21 serieshavebeen 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 tohigh temperature in
rugged environmental conditions.
The typical supply ofthe FLC21 fire lightercircuit is
a DC battery or the AC mains.
