Understanding the NTC 10K B3950 Datasheet: A Deep Dive
An NTC 10K B3950 thermistor is a type of resistor whose resistance decreases as its temperature increases. The “10K” refers to its resistance value at a specific temperature, typically 25°C (room temperature), which is 10,000 ohms. The “B3950” refers to the Beta value, a material constant that characterizes the relationship between resistance and temperature. The datasheet is the manufacturer’s official document providing all the information needed to work with this component. It’s important for engineers and hobbyists alike to understand the datasheet for accurate temperature readings.
