Frequently Asked Questions

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

This HaiWang MF52 thermistor has a nominal resistance (R25) of 3 kilohms (3kΩ) at 25°C. Its B value, which defines the resistance-temperature curve, is 3435 Kelvin (B25/85). This specification ensures a predictable and sensitive response across its operating range.

How do I interface this thermistor with an Arduino or microcontroller?

Interface the thermistor using a simple voltage divider circuit. Connect one thermistor lead to a reference voltage (e.g., 5V or 3.3V) and the other lead to both a pull-down resistor (e.g., a 10kΩ resistor to GND) and an analog input pin on your microcontroller. The voltage at the analog pin will vary with the thermistor's resistance, which your code can convert to temperature using the Steinhart-Hart equation or a lookup table.

What does the 1% tolerance mean for this sensor?

The 1% tolerance indicates the maximum allowable deviation of the actual resistance from its stated nominal value (3kΩ) at the reference temperature of 25°C. A tighter tolerance like 1% provides higher initial accuracy and better consistency between multiple sensors, which is critical for precise temperature measurement and control systems.

Is this thermistor suitable for use in liquids or high-humidity environments?

Yes, the epoxy resin encapsulation provides a firm seal that offers good resistance to moisture and environmental contaminants. This construction allows it to withstand prolonged exposure to conditions like boiling water, making it suitable for applications involving fluids, high humidity, or demanding industrial environments.
