Temperature Sensors - NTC Thermistors

The NCP03WF104E05RL is a NTC type thermistor with an operating temperature range from -40°C to 150°C. It is a non-linear, negative temperature coefficient, thermistor that is used to accurately measure and control temperatures within a wide range of applications. In this article we will look at its application field and working principle.

Application Field

The NCP03WF104E05RL can be used in a wide variety of applications ranging from industrial controllers, HVAC/R, energy management systems, automotive, medical, and consumer products. The thermistor is primarily used for temperature monitoring, measurement, and control in these types of systems. In industrial controllers, the NCP03WF104E05RL is used to monitor and control temperatures in order to ensure efficient operation. It is also used in HVAC/R systems to regulate the temperature of refrigerated spaces, or to adjust for humidity and air changes. In energy management systems, the NCP03WF104E05RL can be used to monitor and adjust for temperature differences between air outlet and inlet in order to control energy consumption. In automotive applications, the NCP03WF104E05RL can be used to monitor engine coolant temperature and adjust accordingly. Finally, it is also used in medical applications to measure body temperature and control vital sign monitoring systems.

Working Principle

At the core of the NCP03WF104E05RL is a bead-type thermistor. The bead-type thermistor is not linear, which means that the resistance of the thermistor will decrease as the temperature increases. The temperature sensitivity is determined by the cut-off frequency, or “Tc” value, of the thermistor. The Tc value is the temperature at which the resistance of the thermistor has decreased to a value of 1/2 the value at zero degrees Celsius. As the temperature increases from zero, the resistance of the thermistor decreases until the Tc value is reached, at which point the thermistor will start to increase in resistance as the temperature continues to rise.

The NCP03WF104E05RL features a wide operational temperature range and very low temperature coefficient of resistance (TCR) between -3.3 and 3.3mV/°C, which allows for a very accurate and responsive temperature measurement. The thermistor is also designed to be used with any type of control circuit, whether digital or analog. Its small size allows it to be used in space-constrained applications, and it is also resistant to aging and contamination, making it suitable for long-term use.

In conclusion, the NCP03WF104E05RL is a reliable and accurate NTC type thermistor with a wide range of applications including monitoring, measurement, and control.
