Positive Temperature Coefficient thermistors are truly re-
markable for their ability to function as self-regulating heating
elements. They can operate at a nearly constant temperature
over a broad range of voltage and dissipation conditions. PTC
heaters can be manufactured in many different configura-
tions. These include discs, rectangles, squares, cylinders,
and various shapes with holes to increase surface area.
Multiple PTCs can be used in parallel to provide constant
heating over a larger area.
Features:
No thermostat needed
Virtually unlimited life
No moving parts to wear
Efficient
Typical Applications:
IC heater
Curling iron
Hair dryer
Hot melt glue gun
Food warmer
Diesel fuel heater
Very low cost
No electrical noise
Instrumentation heater
Plug-in aroma heater
Wax motor
TCXO heater
Liquid Crystal display
Bimetal heater
