100K 3990 Axial Lead Glass Bead Ntc Thermistor Temperature Sensor for Temperature Measurement
The "100K 3990 Axial Lead Glass Bead NTC Thermistor Temperature Sensor" is a highly specialized temperature sensor with specific features that make it suitable for precise temperature measurement in various applications.
100K: Indicates the thermistor's resistance at 25°C, which is 100,000 ohms (100KΩ). This high resistance value makes it particularly sensitive to small temperature changes, making it ideal for applications requiring precise temperature control.
3990: This is the Beta (β) value, a constant that defines the relationship between the thermistor's resistance and temperature. A 3990 Beta value typically covers a temperature range from 25°C to 85°C, allowing for accurate measurements within this range.
Axial Lead: Refers to the configuration of the sensor's leads (wires), which extend from opposite ends of the thermistor. This design makes it easy to mount on printed circuit boards (PCBs) or other electronic assemblies.
Glass Bead: The thermistor is encased in a small bead of glass, providing excellent stability, insulation, and resistance to environmental factors such as moisture, chemicals, and temperature extremes. The glass bead enhances the sensor's durability and ensures long-term reliability.
NTC (Negative Temperature Coefficient): Indicates that the resistance of the thermistor decreases as the temperature increases. NTC thermistors are commonly used in temperature sensing due to their predictable resistance-temperature relationship.
Temperature Sensor for Measurement: This indicates that the sensor is specifically designed for accurate and reliable temperature measurement in various applications.
