Description

The HaiWang MF52 thermistor is a Negative Temperature Coefficient (NTC) sensor whose resistance decreases predictably with increasing temperature. Its 4.7KΩ nominal resistance at 25°C and B-value of 3600K provide a sensitive and stable response curve, making it suitable for temperature measurement, compensation, and control circuits. The epoxy resin encapsulation over the wire leads provides a robust seal against moisture and contaminants, enhancing long-term reliability.

This sensor is designed for easy integration into a wide range of electronic systems. By using it in a simple voltage divider configuration, its analog resistance change can be converted into a precise temperature reading by a microcontroller’s ADC. Its compact size and customizable lead options allow for flexible installation in space-constrained applications, from consumer electronics to industrial equipment.

Frequently Asked Questions

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

This HaiWang MF52 NTC thermistor has a nominal resistance (R25) of 4.7 kilo-ohms (kΩ) at 25°C. Its B-value, which defines the resistance-temperature curve, is 3600K, typically specified between 25°C and 85°C.

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

Interface it using a simple voltage divider circuit. Connect the thermistor in series with a fixed precision resistor (e.g., 4.7kΩ) between your microcontroller's voltage reference (e.g., 5V or 3.3V) and ground. The junction point connects to an analog input pin. The ADC reading is converted to resistance and then to temperature using the Steinhart-Hart equation or a lookup table based on the B-value.

What is the significance of the ±1% tolerance?

The ±1% tolerance on the nominal 4.7kΩ resistance at 25°C indicates high manufacturing precision. This tight tolerance ensures minimal unit-to-unit variation, leading to more accurate and consistent temperature readings without requiring individual calibration for many applications, improving system performance.

Can the epoxy resin coating withstand high temperatures or harsh environments?

Yes, the epoxy resin coating on the wire leads provides firm sealing that enhances durability. It offers good resistance to moisture, mild chemicals, and thermal stress, allowing the sensor to maintain stable performance in demanding environments, including high-humidity applications.
