Temperature Sensors - NTC Thermistors

An NTC thermistor, also referred to as a negative temperature coefficient thermistor, is a type of temperature sensing device that is widely used in many industries and applications. NTC thermistors are made of semiconductor-based materials and have a linear current-temperature relationship. These sensors are most often used for temperature measurement because they are extremely precise, accurate, and economical.

The NC20K00103JBA is a carbon composite NTC thermistor with a negative temperature coefficient, meaning that its resistance decreases as the temperature increases. It has a resistance range of 13kΩ to 48kΩ at 25°C (77°F). This thermistor is designed to operate from -40°C to 125°C (-40°F to 257°F). Additionally, this device’s maximum power dissipation is 1mW.

The NC20K00103JBA is commonly used in a number of different applications such as temperature measurement, temperature compensation, and temperature control. In temperature measurement applications, the thermistor’s resistance is used to measure temperature. When the thermistor is in a closed loop with a constant current, the voltage across it is proportional to the ambient temperature. This voltage signal can then be converted to a temperature reading.

In temperature compensation applications, the thermistor is used to adjust signals so that they remain the same despite changes in temperature. For example, a thermistor can be used to compensate for an increase in temperature, which will in turn reduce the gain error. This is important when precise measurements and controls are necessary.

Finally, in temperature control applications, the thermistor is used to sense the ambient temperature and then trigger a control system to output a certain level of heat in order to maintain the desired temperature. By doing so, the thermistor can minimize the energy required to maintain the temperature.

The NC20K00103JBA is just one example of an NTC thermistor and its possible uses. While the exact specifications and capabilities of this particular thermistor will differ based on the application requirements, the basic design and functionality remain the same. Temperature sensing and controlling devices such as NTC thermistors are essential for many industries, and can be used in a wide variety of applications.
