Description Of The KTY81 PTC Temperature Sensor
Generally, the thermistor part has nonlinear changes in resistance and temperature, and a linear compensation circuit needs to be designed. This product can maintain the linear change of resistance and temperature in the range of -40 degrees to 250 degrees, thereby simplifying the circuit. At present, the resistance temperature characteristic of the common PTC positive temperature thermistor is abrupt, and the linear region is very narrow. This product just complements this wide range of applications.
Commonly used glass-sealed linear thermistor KTY specifications: can replace NXP (PHILIPS) KTY81, KTY82, KTY83, KTY84, KTY85, and RTI's DS series
