A Thermistor NTC 10K is a type of temperature sensor that uses a material with a negative temperature coefficient of resistance to measure temperature changes. It has a nominal resistance of 10,000 ohms at 25°C and can accurately measure temperatures ranging from -40°C to 125°C. It’s commonly used in temperature sensing and control applications, such as in thermostats and HVAC systems. The small size and low cost of thermistor NTC 10K make it an ideal choice for various temperature sensing applications.
Description
A Thermistor NTC (Negative Temperature Coefficient) 10K is a type of temperature sensor that uses a material with a negative temperature coefficient of resistance to measure temperature changes. This means that as the temperature increases, the resistance of the thermistor decreases, and vice versa.
The “10K” in the name refers to the nominal resistance value of the thermistor at a specific temperature, typically 25°C. This means that at this temperature, the thermistor will have a resistance of 10,000 ohms.
Thermistor NTC 10Ks are commonly used in temperature sensing and control applications, such as in thermostats, HVAC systems, and temperature probes. They are often used as part of a voltage divider circuit, where the resistance of the thermistor changes the output voltage of the circuit in proportion to the temperature change.
Thermistor NTC 10Ks are relatively inexpensive and provide accurate temperature measurements over a wide temperature range. They are also relatively small in size and can be easily integrated into electronic circuits. However, they do require calibration to ensure accurate temperature readings and can be affected by self-heating
the technical specifications for a typical Thermistor NTC 10K:
- Temperature range: -40°C to 125°C (may vary depending on the specific model)
- Nominal resistance at 25°C: 10,000 ohms (may vary by a small percentage)
- Tolerance: ±1% to ±5% (the percentage indicates the maximum deviation of the nominal resistance at 25°C)
- Beta value: 3950 K (the beta value is a constant that relates the resistance of the thermistor to temperature, and varies by model)
- Dissipation constant: 1 mW/°C (the amount of power required to change the temperature of the thermistor by 1°C)
- Time constant: 20 to 60 seconds (the time it takes for the thermistor to respond to a temperature change, may vary depending on the specific model and mounting configuration)
- Operating voltage: typically 3 to 5 volts DC
- Operating current: typically less than 1 mA
- Size: typically small, ranging from 2 to 10 mm in diameter and 3 to 15 mm in length
- Mounting: often provided with a small bead or glass enclosure for easy mounting and protection from mechanical stress and moisture.
