Decoding the Ntc 100k 3950 Datasheet What It Is and Why It Matters
An NTC 100k 3950 thermistor is a type of resistor whose resistance changes significantly with temperature. The "100k" in its name refers to its resistance of 100,000 ohms (or 100 kilohms) at a standard reference temperature, typically 25 degrees Celsius. The "3950" signifies the B-value, a crucial parameter that defines the thermistor's temperature-resistance characteristic. This B-value, often expressed as Kelvin (K), dictates how much the resistance changes for each degree Celsius or Fahrenheit change in temperature. The Ntc 100k 3950 Datasheet provides the essential specifications, performance curves, and electrical characteristics necessary to accurately implement and utilize this thermistor.
These thermistors are widely used across various applications due to their sensitivity and cost-effectiveness. They act as reliable temperature sensors in:
- Home appliances like refrigerators, ovens, and thermostats.
- Automotive systems for engine temperature monitoring and climate control.
- Medical devices requiring precise temperature regulation.
- Industrial process control and environmental monitoring.
The Ntc 100k 3950 Datasheet details the thermistor's behavior across a range of temperatures, allowing engineers and hobbyists to calculate precise temperature readings. This involves understanding the Steinhart-Hart equation or using lookup tables provided in the datasheet to convert resistance measurements into actual temperatures. The datasheet will typically include:
| Parameter | Typical Value |
