P/N 1600-10K Thermistor

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’).

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:
