Temperature Sensors - NTC Thermistors

Temperature sensing devices are devices that measure temperature. These devices are used in applications such as heating, air conditioning, refrigeration, energy management, motor control, chemical processing, data logging, instrumentation, and aerospace. Of the various temperature sensing devices, such as thermocouples, RTD, thermistor, infrared pyrometers, and thermoelectric devices, NTC thermistors are the most popular for applications requiring a low price point.

An NTC thermistor is a temperature sensitive resistor that changes resistance in proportion to a change in temperature. The NTC thermistor is most popular due to its small size, low cost, accurate temperature sensing, and quick response. There are five basic parameters used to describe thermistors: resistance at room temperature, temperature coefficient of resistance (TCR), resistance tolerance, B constant, and power rating.

NCP03 WF104J05RL is a NTC thermistor from Isabellenhütte. It is a 2-pin, surface mount device with excellent stability of parameters at epoxy encapsulation. NCP03 WF104J05RL has a nominal resistance of 10 KΩ ±1% at 25°C and a strain coefficient of 5. Made with metallic glaze construction, NCP03 WF104J05RL has a power rating of 1/2W and a B-constant value of 3380. It has a maximum operating temperature of 150°C with an insulation resistance of 1000MΩ+/50V.

The working principle of NCP03WF104J05RL is based on the negative temperature coefficient of resistance. When temperatures rises, the electrical resistance of the thermistor also increases. This effect is mainly due to the changes in the lattice structure and density of the ceramic material as the temperature rises. This in turn results in an increase in electrical resistance. Since the resistance of the thermistor increases as the temperature rises and vice versa this device has become ideal for temperature sensing applications.

NCP03WF104J05RL is generally used in a variety of applications such as temperature control, thermal overload protection, communications, measurement and control, switchgear, power supply, heating, and cooling systems. It is also used in automotive and white goods applications like air conditioners and refrigerators. It can be used in thermal fuses, temperature compensation, and industrial equipment.
