PTC Heater
Resistors And
Resistive Applications
PTC or “Positive Temperature Coefficient of Resistance” heaters are safe
and reliable thermistors made of functional semiconductor materials. As the
temperature increases beyond the Tc point, the resistance goes down and
the temperature falls below Tc point. Then the resistance increases again.
This kind of effect is called the “PTC domino effect”.
