Working Principle

NTC thermistors are semiconductors with a predictable change in resistivity as a function of temperature. The SM04103372 uses a negative temperature coefficient (NTC) that is applied to temperature sensing applications. When an NTC thermistor is exposed to an increase in temperature, it decreases in resistance. The RTC for the SM04103372 is 3950K.

When an electric current is sent through an NTC thermistor, the resistance is inversely proportional to the temperature. The higher the temperature, the lower the resistance. The resistance of an NTC thermistor can be calculated using the Steinhart-Hart equation, which uses the thermistor\'s temperature-dependent resistance to estimate the component temperature.

With operating temperatures ranging from -40°F to +200°F (-40°C to +93°C), SM04103372 is suitable for a wide range of applications. It is ideal for use in medical applications and other temperature-focused applications requiring accuracy and reliability. Additionally, the SM04103372 has a variety of features that make it extremely durable such as its high accuracy, wide operating temperatures, and the ability to operate even in harsh environments.

Conclusion

The SM04103372 NTC thermistor is a popular temperature sensor that is used in a variety of applications. Due to its wide operating temperatures ranging from -40°F to +200°F, its reliable RTC value of 3950K, and its extremely durable features, the SM04103372 is a great choice for any temperature sensing application that requires accuracy and reliability.
