The KTY81/210.112 is a device manufactured by NXP Semiconductor and is part of their NTC Thermistor (Negative Temperature Coefficient) series of temperature sensors. This thermistor is composed of a metal oxide material that exhibits a negative temperature coefficient, meaning that as the temperature increases, the resistance of the thermistor decreases. This thermistor is a 1206 size package, meaning it measures 3.2 Millimeters x 1.6 Millimeters and is capable of withstanding a temperature range of -55°C to +150°C. Its nominal resistance at 25°C (77°F) is 10K Ohms +/- 1%.
