Temperature Sensors - NTC Thermistors

NTC thermistors are thermally sensitive resistors that have a negative temperature coefficient, meaning that their electrical resistance decreases with an increase in temperature. They are primarily used to measure and control temperature in industrial processes, to measure temperature in consumer applications, and to detect an over-temperature condition in safety applications. The SM104J1O-TR is a common NTC thermistor.

What Is the SM104J1O-TR?

The SM104J1O-TR is a type of NTC thermistor manufactured by the company Seiko Instruments USA. It is a chip thermistor made of PPAR material, a plastic material with superior thermal resistance and stability. It features a 0.85mm housing size and has a wide range of resistance-temperature characteristics.

Applications

The SM104J1O-TR can be used in a variety of different applications. It is a widely used as a temperature sensor in consumer and industrial products, such as air conditioners, ovens, refrigerators, and dishwashers. It can also be used as an over-temperature control device in machines and equipment applied in dangerous environments, such as those used in medical, automotive, and aerospace applications.

Working Principle

The SM104J1O-TR is an NTC thermistor, meaning that its resistance decreases in response to increases in temperature. This relationship between resistance and temperature can be described by a mathematical equation known as the B-Value equation. The B-Value equation is used to calculate the thermistor\'s resistance value at a given temperature, based on its resistance value at a reference temperature. The SM104J1O-TR\'s B-Value is 3800K.The electrical resistance of the SM104J1O-TR depends upon the temperature of its surrounding environment. When the temperature rises, the electrical resistance drops, and vice versa. This property of the SM104J1O-TR makes it a very useful device to measure and control temperature. The device can be wired in series or parallel with an electronic circuit, and its output signal can be read by a thermocouple or other type of temperature sensor.

Advantages

The SM104J1O-TR is widely used because of its small size and superior thermal performance. It offers accurate and reliable temperature sensing, and its wide range of resistance-temperature characteristics makes it suitable for measuring temperatures ranging from -20 to +105 degrees Celsius. Its PPAR material construction also makes it highly resistant to corrosion and vibration, making it well-suited for applications in hazardous environments.

Conclusion

The SM104J1O-TR is a widely used NTC thermistor that provides accurate temperature sensing and control. It offers a range of resistance-temperature characteristics suitable for measuring temperatures in hazardous environments, and its PPAR material construction makes it resistant to corrosion and vibration. It is an ideal solution for a variety of industrial, consumer, and safety applications.
