The thermistor is able to measure temperatures from -55 to +105°C with high accuracy. Such applications include automotive, telecommunication, consumer electronics, medical, industrial and electronic ballast. Other applications include HVAC, motor protection and control, refrigerator, energy meter and various instruments.

Working principle

NTC thermistors are temperature sensors that have an electrical resistance which varies with ambient temperature changes. As temperature increases, the resistance of the thermistor decreases exponentially. The basic principle of operation is that as the temperature increases, the semiconductor material changes its electrical resistance accordingly. This change in resistance can then be used to measure the temperature and accurately calculate the resistance value.

The thermistor is composed of a negative temperature coefficient (NTC) semiconductor material and resistor elements. When temperature increases, electrons are freed from the semiconductor material, this lowers the resistance of the thermistor.The change in electrical resistance of the thermistor can be used to measure temperature with the help of a low-resistance bridge circuit.

The major components of the bridge circuit include the thermistor, a reference resistor, an operational amplifier and a power source. When the reference resistor and the thermistor are connected to the operational amplifier and power source, a voltage is measured across it. This voltage is then used to calculate the resistance of the thermistor and the temperature. The thermistor is also used in conjunction with temperature controllers and temperature sensors in industrial settings for temperature control and monitoring.

Conclusion

The NTCS0805E3103HHT is a type of NTC thermistor which is suitable for many temperature sensing applications where accurate measurements are required. Since it has a high absolute accuracy and a low temperature coefficient of resistance, it can provide reliable and accurate measurements over a wide range of temperatures. The thermistor\'s working principle is based on the change in electrical resistance due to a change in ambient temperature and is used in conjunction with other circuit components in order to accurately measure temperature.
