Frequently Asked Questions

What is the nominal resistance and B-value of this NTC thermistor?

This HaiWang MF58 thermistor has a nominal resistance of 10 kilo-ohms (10KΩ) at the reference temperature of 25°C. Its B-value, which defines the resistance-temperature curve, is 3950 Kelvin (K), providing high sensitivity across its operating range.

What does the 1% tolerance specification mean for this sensor?

The 1% tolerance indicates the maximum allowable deviation of the actual resistance from its stated nominal value (10KΩ) at 25°C. This high precision ensures consistent and accurate temperature measurement readings, making it suitable for applications requiring reliable thermal monitoring and control.

How does the glass encapsulation benefit the sensor's performance?

The glass encapsulation provides a hermetic seal that protects the internal thermistor element from moisture, humidity, and corrosive environmental factors. This enhances long-term stability, prevents resistance drift, and allows reliable operation in challenging conditions like high-temperature, high-humidity industrial or outdoor settings.

How do I interface this thermistor with a microcontroller like Arduino?

The thermistor is typically used in a voltage divider circuit with a series reference resistor. Connect one lead to your microcontroller's analog input pin and the other to ground, with the reference resistor connected to the positive supply. You then use the Steinhart-Hart equation or a lookup table in your code to convert the measured voltage into an accurate temperature reading.
