The 3K NTC thermistor is a highly reliable electronic component used for temperature measurement and control. It is widely utilized in various industries, including automotive, aerospace, medical, and consumer electronics. This thermistor is designed based on the Negative Temperature Coefficient (NTC) principle, which means its resistance decreases with an increase in temperature.

Working Principle

The 3K NTC thermistor operates on the principle of variable resistance. As the temperature changes, the electrical resistance of the thermistor changes accordingly. This change in resistance can be measured and used to determine the temperature. The 3K value indicates that the thermistor has a resistance of 3,000 ohms at 25°C.


The 3K NTC thermistor finds extensive applications in temperature sensing and control systems. Some common uses include:

  • Temperature monitoring in electronic devices
  • Thermal protection in power supplies
  • Temperature compensation in battery charging circuits
  • Temperature control in HVAC systems
  • Medical temperature monitoring


The 3K NTC thermistor offers several advantages, making it a preferred choice in many temperature sensing applications:

  1. High accuracy and sensitivity
  2. Wide temperature range (-50°C to +150°C)
  3. Rapid response time
  4. Compact size and ease of integration
  5. Cost-effective solution

In conclusion, the 3K NTC thermistor is a crucial component for temperature sensing and control systems across various industries. Its reliable performance, broad temperature range, and compact design make it an ideal choice for numerous applications.
