Introduction to NTC Thermistors

NTC (Negative Temperature Coefficient) thermistors are temperature-sensitive resistors that exhibit a decrease in resistance as the temperature rises. These electronic components are widely used in various industries for temperature sensing, compensation, and control applications.

Understanding 100k NTC Thermistors

The “100k” in “100k NTC Thermistor” refers to the nominal resistance value at a specific temperature. In this case, it indicates that the thermistor has a nominal resistance of 100,000 ohms at a given temperature, typically 25 degrees Celsius.

100k NTC thermistors are commonly used in temperature measurement and control systems due to their high sensitivity and accuracy. Their small size and fast response make them suitable for various applications, including automotive, medical, HVAC, and industrial equipment.

Key Specifications of 100k NTC Thermistors

When selecting a 100k NTC thermistor, several key specifications should be considered:

  1. Resistance at 25°C: The resistance value at the standard reference temperature of 25°C.
  2. Beta Value: The Beta value, also known as the temperature coefficient, indicates how the resistance changes with temperature. It is an essential parameter for temperature compensation.
  3. Tolerance: The tolerance specifies the allowable deviation from the nominal resistance value.
  4. Operating Temperature Range: The temperature range within which the thermistor can operate effectively.
  5. Thermal Time Constant: The time required for the thermistor to reach approximately 63.2% of its final resistance when subjected to a step change in temperature.

Applications and Usage

100k NTC thermistors find applications in a wide range of industries and products, including:

  • Temperature sensors
  • Thermostats and HVAC systems
  • Medical devices
  • Automotive temperature monitoring
  • Industrial process control

Additionally, they are often used for temperature compensation in electronic circuits to improve stability and accuracy.

In conclusion, the 100k NTC thermistor datasheet provides essential information about its specifications and usage. When selecting a thermistor for your application, carefully review the datasheet to ensure compatibility with your requirements.
