Description

The HaiWang MF52 thermistor is a Negative Temperature Coefficient (NTC) sensor whose resistance decreases predictably as temperature increases. Its 3950 B-value defines the steepness of the resistance-temperature curve, making it highly sensitive and suitable for precise measurement across a broad range. The epoxy resin coating on the wire leads seals the connection points, enhancing durability in humid or condensing environments.

This sensor operates as a passive component, requiring a simple voltage divider circuit with a pull-up resistor to interface with an analog-to-digital converter (ADC) on microcontrollers like Arduino, ESP32, or Raspberry Pi. Its 1% tolerance on the nominal 50KΩ resistance at 25°C provides excellent measurement consistency, reducing the need for individual calibration in batch applications.

Key Features

  • High-Precision NTC Sensing: 50KΩ nominal resistance at 25°C with a tight 1% tolerance and standardized 3950 B-constant for reliable temperature characterization.
  • Robust Environmental Sealing: Epoxy resin-coated wire leads offer firm sealing, protecting the sensor junction from moisture ingress and extending operational life.
  • Compact & Mountable Design: The standard MF52 epoxy-coated bead package facilitates easy through-hole PCB mounting and integration into assembled devices.
  • Wide Application Compatibility: Suitable for temperature measurement, compensation, and control circuits in consumer electronics, automotive systems, and industrial equipment.
  • Proven Durability: Constructed to withstand prolonged exposure to high-humidity and elevated temperature conditions, ensuring long-term stability.
  • Standardized Electrical Parameters: Consistent performance across batches simplifies circuit design and system calibration.

Applications

  • Temperature monitoring and thermal protection in power supplies, battery packs, and motor drivers.
  • Environmental temperature sensing for HVAC systems, weather stations, and smart home controllers.
  • Temperature compensation circuits for oscillators, crystal references, and precision analog electronics.
  • Consumer appliance temperature control, including coffee makers, 3D printer hotends, and soldering stations.
  • Industrial process monitoring where cost-effective, reliable point temperature measurement is required.

Frequently Asked Questions

What is the resistance value and tolerance of this HaiWang MF52 thermistor?

This HaiWang MF52 thermistor has a nominal resistance of 50 kilo-ohms (50KΩ) at 25°C, with a tight manufacturing tolerance of ±1%. This high precision ensures consistent and accurate temperature-to-resistance characteristics for reliable sensing.

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

Interface the thermistor using a simple voltage divider circuit. Connect one lead to your microcontroller's ADC pin via a pull-up resistor (e.g., 10KΩ), and the other lead to ground. The ADC will read a voltage that varies with the thermistor's resistance, which your code can convert to temperature using the Steinhart-Hart equation or a lookup table based on the B3950 value.

What does the 'B3950' value mean, and what is the epoxy resin coating for?

The 'B3950' is the material constant (B-value) that defines the shape of the thermistor's resistance vs. temperature curve between 25°C and 85°C. A value of 3950 indicates high sensitivity. The epoxy resin coating on the wire leads provides a firm seal, protecting the internal bead and solder joints from moisture, dust, and mechanical stress, thereby enhancing durability.
