NTC thermistors are non-linear temperature-sensitive resistors that can be widely used in temperature sensing solutions. The 143-201FAG-A02 is a two pin thermistor with optimal temperature detection range from -20°C to 135°C, designed specifically for temperature monitoring applications. This device offers a high degree of accuracy and fast response time across its broad measuring range. It can be used in high temperature alarm systems, production and laboratory test equipment, automotive, medical, and industrial monitoring applications.

The 143-201FAG-A02 is a negative temperature coefficient (NTC) thermistor, with resistance that decreases with increasing temperature. The thermistor has a temperature coefficient of -3.125%/°C. This means that its resistance increases by 3.125% for every 1°C decrease in temperature. This high precision thermistor features a low self-heating effect, ensuring accurate and highly reliable temperature measurement at all times. It also features low electric noise and low temperature hysteresis, both of which help minimize any disruptions in temperature readings.

The working principle of an NTC thermistor is based on the negative temperature coefficient of certain materials. Depending on the material used in the thermistor, in response to an increase in temperature, the resistance of the thermistor decreases. Similarly, when the temperature decreases, the resistance increases. This change in resistance is used to measure the temperature by connecting it to a suitable circuit. This circuit consists of a microcontroller, an amplifier and a power source.

The microcontroller is used to detect the change in resistance of the thermistor. It does so by measuring the voltage drop across the thermistor. This voltage drop is fed to the amplifier, which amplifies the signal and sends it to the microcontroller. The microcontroller then processes the signal, calculates the temperature, and accordingly generates a control signal that can be used to start or stop cooling/heating systems. This helps maintain the room temperature at the desired level.

In summary, the 143-201FAG-A02 is an NTC thermistor, designed specifically for temperature sensing applications. It has a broad temperature detection range and excellent accuracy and fast response times. Its working principle is based on the fact that the resistance of the material used in the thermistor changes in response to temperature changes. The thermistor is connected to a suitable circuit that consists of a microcontroller, an amplifier, and a power source. The circuit detects the voltage drop across the thermistor, and depending on the temperature, generates appropriate control signals required to regulate the temperature.
