Description

The MF58 series NTC thermistor operates on the principle of a negative temperature coefficient, where its electrical resistance decreases predictably as temperature increases. This precise R-T characteristic, defined by its 4050 B-value, allows for accurate temperature measurement and control when integrated with a simple voltage divider circuit or microcontroller ADC input.

Encapsulated in a robust glass housing, the sensor is protected against moisture and corrosive atmospheres, ensuring long-term reliability and stable performance in challenging industrial and automotive environments. Its small form factor and leaded design facilitate automated assembly onto printed circuit boards for high-volume production.

Key Features

  • Precision NTC Thermistor: 47KΩ nominal resistance at 25°C with a tight ±1% tolerance for consistent performance.
  • Stable Glass Encapsulation: Hermetic glass seal provides excellent protection against humidity, thermal shock, and chemical exposure.
  • Wide Operational Range: Suitable for temperature sensing applications across a broad spectrum, from consumer electronics to industrial process control.
  • Fast Thermal Response: Low thermal mass enables quick detection of temperature changes for real-time monitoring and feedback loops.
  • Robust Mechanical Design: Strong lead frame and glass body ensure durability against vibration and mechanical stress.
  • Optimized Performance-to-Cost Ratio: Delivers high accuracy and environmental durability in a cost-effective package for volume applications.

Applications

  • Temperature control and overtemperature protection in household appliances (air conditioners, microwave ovens, electric heaters).
  • Battery temperature monitoring and management in mobile devices, power tools, and energy storage systems.
  • Precision temperature compensation for crystal oscillators, integrated circuits, and instrumentation coils.
  • Process temperature sensing in industrial equipment, medical devices, and environmental monitoring stations.

Frequently Asked Questions

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

This HaiWang MF58 thermistor has a nominal resistance of 47 kilo-ohms (47KΩ) at the standard reference temperature of 25°C. Its B-value, which defines the resistance-temperature curve between 25°C and 85°C, is 4050 Kelvin. These parameters are critical for calculating precise temperature from measured resistance.

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

Interface the NTC thermistor using a simple voltage divider circuit. Connect one thermistor lead to your microcontroller's supply voltage (e.g., 5V or 3.3V) and the other lead to both a pull-down resistor (e.g., a 47KΩ resistor for optimal range) and an analog input pin. The other end of the pull-down resistor connects to ground. The microcontroller reads the voltage at the junction and calculates temperature using the Steinhart-Hart equation or a lookup table based on the 4050 B-value.

What are the advantages of the glass encapsulation on this sensor?

The glass encapsulation provides a hermetic seal, making the sensor highly resistant to moisture, humidity, and corrosive atmospheres. This ensures long-term stability and reliability of the resistance value, preventing drift in high-temperature, high-humidity environments commonly found in industrial, automotive, or outdoor applications. The glass package also offers robust mechanical protection against vibration and thermal shock.
