Infineon KTY81 PTC Temperature Sensor 1K Ohm LPTC81-110 KTY81-120 121 122 150 151 152
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
Application Of The KTY81 PTC Temperature Sensor
Widely used in temperature control, temperature measurement and
temperature compensation in communications, automobiles,
instruments, computers, home appliances and other industries. The
resistance temperature characteristic of the common PTC positive
temperature thermistor is abrupt, and the linear region is very
narrow. It is usually used for overcurrent protection of circuits,
not for temperature detection and temperature compensation
circuits. This product just complements this field of application.
1. Automotive industry temperature detection and control
