Temperature sensors in the form of thermistors, or negative temperature coefficient (NTC) thermistors, serve as a form of heat-sensing device in a variety of applications. The NTCG164BH222HT1 is a thermistor with a wide operating voltage range and low temperature coefficient of resistance (TCR). Using a simple resistance-temperature relationship, the NTCG164BH222HT1 is able to sense changes in temperature with great accuracy and precision.

This thermistor is ideal for residential and commercial temperature sensing, as well as automotive and HVAC applications. It features a positive temperature coefficient (PTC) from 0°C to 70°C, plus a negative temperature coefficient (NTC) from 70°C to 110°C. This provides greater accuracy in the temperature ranges most used by these applications. The NTCG164BH222HT1 can measure temperatures from -40°C to +–25°C, and is rated to withstand up to +–12V spikes on its operating voltage.

The NTCG164BH222HT1 thermistor works by relying on a principle that the resistance of a material changes in relation to its temperature. The thermistor itself is a small semiconductor device with two leads. As the temperature increases, its structure changes and the resistance of the thermistor decreases. This change in resistance is measured across the leads, and the corresponding temperature is then read.

A voltage is applied across the two leads in order to measure the resistance of the thermistor. The resistance along the device increases with a decrease in temperature. This, in turn, causes the voltage across the leads to decrease. The amount of voltage present allows the device to be approximately calibrated to the temperature.

The NTCG164BH222HT1 thermistor is equipped with an NTC resistor on the cathode side of the device, while a PTC resistor is located on the anode side. The NTC resistor is capable of measuring temperatures from 184K (–88°C) to 294K (–21°C), while the PTC resistor is able to measure temperatures from 294K (–21°C) to 551K (277°C).

The NTCG164BH222HT1 is a high-accuracy thermistor that offers excellent uniformity and temperature stability. It is also designed to offer a minimal temperature coefficient of resistance, making it a great choice for applications that require precise temperature sensing.

The NTCG164BH222HT1 is a great choice of thermistor for temperature sensing applications, such as building automation, automotive, HVAC and industrial control systems. Its wide voltage range and low temperature coefficient of resistance make it a perfect fit for these applications. It is also capable of withstanding spikes in voltage, which further increases its stability and accuracy.
