Description

The HaiWang MF52 thermistor operates on the principle of a Negative Temperature Coefficient (NTC), where its electrical resistance decreases predictably as temperature increases. This characteristic makes it an excellent, cost-effective sensor for temperature measurement, compensation, and control circuits. The epoxy resin encapsulation on the wire leads provides a firm seal, enhancing durability against environmental factors like humidity and brief fluid exposure.

Designed for easy integration, this thermistor can be used with a simple voltage divider circuit to provide an analog voltage output proportional to temperature, which can be read by any microcontroller ADC pin. Its standardized package and electrical parameters make it a versatile component for prototyping, industrial instrumentation, HVAC systems, and consumer electronics requiring thermal management.

Key Features

  • High-precision NTC thermistor with specified 20KΩ resistance at 25°C reference.
  • Stable B-value (Beta constant) of 4150K ensures linearized temperature-resistance relationship.
  • Epoxy resin-coated wire leads offer improved mechanical strength and environmental sealing.
  • Compact and standardized MF52 package footprint for easy PCB layout and assembly.
  • Designed for reliable performance across a broad temperature sensing range.
  • High-value build suitable for both prototyping and volume production applications.

Applications

  • Temperature monitoring and compensation in power supplies and battery management systems.
  • Environmental data logging for weather stations and indoor climate control systems.
  • Over-temperature protection and thermal management in consumer electronics and appliances.
  • DIY and educational projects with Arduino, Raspberry Pi, and ESP32 platforms for sensing.
  • Industrial process control and equipment where cost-effective point temperature sensing is required.

Frequently Asked Questions

What is the resistance value of this thermistor at room temperature?

This HaiWang MF52 thermistor has a nominal resistance of 20 kilo-ohms (20KΩ) specifically at 25°C. The B-value (Beta constant) is 4150K, which defines the resistance-temperature curve for accurate calculation across its operating range.

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

Interface the thermistor using a simple voltage divider circuit. Connect the thermistor in series with a fixed precision resistor (e.g., 20KΩ) between Vcc and GND. The junction point connects to an analog input pin on your microcontroller. Use the Steinhart-Hart equation or a lookup table in your code to convert the measured voltage into temperature.

What does the epoxy resin coating on the wires provide?

The epoxy resin coating on the lead wires provides a firm, durable seal that protects the internal semiconductor material from moisture, humidity, and minor chemical exposure. This enhances the sensor's longevity and reliability in non-hermetic applications, including environments with condensation or occasional splashes.
