PTC Thermistor: Positive Temperature Coefficient Thermistor
A PTC (Positive Temperature Coefficient) thermistor is a type of thermistor whose electrical resistance increases with an increase in temperature. This characteristic distinguishes it from NTC (Negative Temperature Coefficient) thermistors, where resistance decreases with temperature. Key Features of PTC Thermistors: Positive Temperature Coefficient: The most defining feature of PTC thermistors is their positive temperature coefficient. As the temperature rises, the resistance of a PTC thermistor increases, providing a predictable and measurable response to temperature changes. Applications:- Overcurrent Protection: PTC thermistors are often employed as self-resetting fuses or overcurrent protection devices. When subjected to an overcurrent condition, the temperature of the PTC thermistor increases, causing a significant rise in resistance and limiting the current flow.
- Temperature Sensing: PTC thermistors are used in temperature-sensing applications where their resistance variation with temperature is utilized to measure or control temperature in electronic circuits.
