NTC thermistors are temperature sensing devices that are widely used in areas such as motor and heating control systems. They detect temperature changes by measuring the resistance of the thermistor, which is temperature-dependent. The resistance of a thermistor decreases as the temperature rises. The 173-103LAF-301-WRI is a type of NTC thermistor, which is a popular choice for applications that require accurate temperature measurement.

The 173-103LAF-301-WRI can measure temperatures between -30°C ~ +60°C. It is highly resistant to vibration and shock with a minimum required temperature coefficient of 0.1%/°C. This thermistor features low self-heating of 0.05 %/°C and a high accuracy of ±0.1°C. It is also capable of withstanding high-temperature environments up to +200 °C. Additionally, it has excellent long term stability and a maximum thermal time constant of 4.5 Sec.

The 173-103LAF-301-WRI thermistor functions by monitoring resistive changes in response to temperature variations. The thermistor is composed of a terminal, a substrate, and a sensitive sensing element. The sensing element is usually made of MnO₂ and is protected by an epoxy package. The core of the element is connected to the metal terminal, which contains the thermistor’s W/K resistance values.

When the ambient temperature changes, the resistance of the NTC thermistor changes accordingly. The amount of resistance alteration is determined by the temperature coefficient, which is specified in the datasheet of the thermistor. The resistance of the thermistor decreases in a linear manner with increasing temperature. This change in resistance is detected by the circuit, which results in a change in voltage across the thermistor.

The 173-103LAF-301-WRI has a wide range of applications. It is used in automotive, air conditioners, home appliances, boilers, and medical equipment for temperature sensing and control. It is also used in motor, heating, and other control systems, where accurate temperature measurement is required. Additionally, the NTC thermistor is used in environmental monitoring systems, such as temperature and humidity monitoring systems, to detect temperature changes.

In conclusion, the 173-103LAF-301-WRI NTC thermistor is a popular choice for applications that require accurate temperature measurement. It features excellent shock and vibration resistance as well as a wide temperature range and a high accuracy of ±0.1°C. Additionally, it can be used in a variety of temperature sensing and control applications.
