1. Definition

A glass radial NTC (Negative Temperature Coefficient) thermistor is a type of temperature sensor that exhibits
inverse relationship between its resistance and temperature. It consists of a small bead of glass or ceramic
material with a high negative temperature coefficient. The bead is encapsulated in a radial leaded package,
allowing easy integration into electronic circuits for temperature sensing applications.

2. Working Principles

Glass radial NTC thermistors operate based on the principle of the negative temperature coefficient of
semiconductors. As the temperature increases, the number of charge carriers in the thermistor material
significantly rises, leading to a decrease in resistance. Conversely, as the temperature decreases, the
resistance of the thermistor increases proportionally. This unique characteristic allows glass radial NTC
thermistors to accurately measure temperature changes across a wide range.

3. Applications

Glass radial NTC thermistors have various applications in a range of industries. Some common usages include:

  • Temperature monitoring and control systems
  • Appliances and HVAC systems
  • Medical devices and equipment
  • Industrial process control
  • Automotive climate control

4. Advantages

Glass radial NTC thermistors offer several advantages:

  1. Precision and accuracy in temperature measurements
  2. Fast response time
  3. Wide temperature range capability
  4. Stability and reliability under varying conditions
  5. Cost-effective compared to other temperature sensing solutions

5. Considerations

When using glass radial NTC thermistors, it is essential to consider the following:

  • Operating temperature range
  • Tolerance and interchangeability
  • Thermal response time
  • Packaging and mounting requirements
  • Circuit protection
