P/N 1600-10K Thermistor Thermistor Resistance vs Temperature Chart The enclosed negative temperature coefficient (NTC) thermistor, p/n 1600-10K, works by translating temperature into resistance, with resistance decreasing as temperature increases (hence the ‘negative coefficient’). 50000 Resistance (Ω) 40000 30000 20000 10000 0 -10.00 10.00 30.00 50.00 70.00 Temperature (°C) 90.00 110.00 Typical Resistance vs. Temperature Graph As can be seen be the graph, the resistance of the thermistor drops very quickly. In the typical control range (0°C to 40°C), 10K thermistors offer good sensitivity to changes in temperature, and this is the range in which most 10K thermistors are typically used. 10K thermistors can be used at much higher temperatures, but will suffer poorer temperature stability performance because of the lower sensitivity. The Steinhart-Hart Equation Resistance varies inversely with temperature in a non-linear fashion. This relationship can be accurately modeled by the Steinhart-Hart equation: 1 A B * ln( R) C * ln( R) 3 T Where: A = 1.12924E-03 B = 2.34108E-04 C = 0.87755E-07 Copyright © 2012, Arroyo instruments.
