NTC10K B3950 Temperature-Resistance Table
NTC10K B3950 NTC Thermistor Resistance vs Temperature Table
1. Basic Information
NTC10K B3950 is a commonly used negative temperature coefficient (NTC) thermistor with a nominal resistance of 10KΩ at 25°C and a B value of 3950K (B25/50). It is widely used in temperature measurement, temperature control, temperature compensation, and other fields such as air conditioning, water heaters, refrigerators, and medical equipment.
1.1 Formula
The resistance-temperature relationship of NTC thermistors follows the B-value equation (simplified Steinhart-Hart equation):
R(T): Resistance at temperature T (Ω)
R₀: Nominal resistance at 25°C (10kΩ)
B: B value (3950K, B25/50)
T: Temperature (K) = Temperature (°C) + 273.15
T₀: Reference temperature (298.15K = 25°C)
