The PTC Effect and Temperature Control

The PTC effect is a phenomenon that allows PTC heaters to self-regulate their temperature. This effect is based on the principle that when the material’s temperature rises, so does its resistance. Temperature control in these heaters is due to this effect.

Let’s take a look at the following table. It shows the correlation between the temperature range and the resistance range:

Temperature RangeResistance Range
Below Curie PointLow resistance
At Curie PointRapid increase
Above Curie PointHigh resistance

Below the material’s Curie point, the resistance is low. When the temperature reaches the Curie point, the resistance skyrockets. This limits the current flow and prevents overheating.

PTC heaters are self-regulating. As they heat up due to electrical current, the resistance rises. This keeps temperature more stable.
