PTC positive temperature coefficient thermistor Characteristic

Positive Temperature Coefficient Thermistor Material Structure - It is made of barium titanate (BaTiO3), strontium (Sr), zirconium (Zr) and other materials.
The positive temperature coefficient thermistor belongs to the direct thermal type thermistor.
Characteristics - Resistance values are proportional to temperature changes,That is, when the temperature increases the resistance value increases.At room temperature, its resistance is small,Only a few ohms to tens of ohms;When the current flowing through it exceeds the rated value,Its resistance value in a few seconds to quickly increase to hundreds of ohms to thousands of ohms or more.
Function and Application -Widely used in color TV degaussing circuit,Refrigerator compressor start circuit and overheating or over-current protection circuit,Can also be used for electric mosquito and curlers, electric pads, heaters and other small appliances.
