Model 10K103 NTC Thermistor Probe for Smart Fan Control

　　Through the intelligent temperature control function, the fan can sense the temperature of the environment to adjust the speed of the fan to achieve better working results.

　　Application schematic diagram of intelligent control fan NTC thermistor:

　　The fan is controlled by heating an NTC thermistor, where the speed of the fan depends on the temperature of any device, like a PC. As the temperature of the device increases or decreases, the fan speed increases or decreases, respectively. Therefore, it can be mainly used as a cooling device. With a slight modification to the circuit, it can also be used to control room temperature, depending on the characteristics of the thermistor. The thermistor used in the circuit here decreases its resistance as the temperature increases, so the conductivity also increases, increasing the voltage, which results in an increase in the fan speed. Therefore, when the temperature of the device changes, the speed of the fan can be automatically controlled.

　　The NTC thermistor features:

　　• Wide operating temperature range, good stability and reliability.

　　•Easy to install and operate because sealing can be done according to the environment and conditions of the customer's application.

　　• Accurate testing can accurately reflect temperature changes.

　　• Insulation resistance (MΩ): over 100MΩ one ton DC500 V

　　• Operating temperature range (°C): - 5 0 ~ +1 50

　　• Dissipation factor (mw/°C): 1-2 (still air)

　　• Thermal time constant: within 10-25 seconds (in air)

　　parameter:

　　• R @ 25°C: 1k - 100kΩ.

　　•R@25°C accuracy values: ±1%, ±2%, ±3%, ±5%

　　•B value @ 25℃/50℃: 3380, 3470, 3700, 3950 etc.
