Positive Temperature Coefficient

Description: Positive Temperature Coefficient (PTC) refers to the property of a material or component that exhibits an increase in resistance as its temperature rises. This behavior is opposite to the Negative Temperature Coefficient (NTC), where resistance decreases with increasing temperature.

Sample sentences:

The positive temperature coefficient of this thermistor makes it ideal for temperature control applications.
When the temperature reached a certain threshold, the PTC resistor caused the circuit to shut down.
PTCs are commonly used in self-regulating heaters, where their resistance increases as they heat up, preventing overheating.
