Description

The MF52 thermistor operates on the principle of Negative Temperature Coefficient (NTC), where its electrical resistance decreases predictably as temperature increases. This characteristic makes it ideal for temperature sensing, control, and compensation in circuits. The epoxy resin encapsulation provides a robust seal, protecting the semiconductor element from moisture and mechanical stress.

With its standardized B-value curve, this sensor can be easily interfaced with microcontrollers like Arduino or Raspberry Pi using a simple voltage divider circuit for analog temperature reading. Its durability and stable performance suit it for applications requiring consistent thermal monitoring over extended periods.

Key Features

  • High-precision NTC thermistor with 100KΩ @ 25°C and B3950 value.
  • Epoxy resin-coated wire leads offer excellent moisture resistance and mechanical protection.
  • Wide operating temperature range suitable for general-purpose and industrial environments.
  • Compact, through-hole design for straightforward PCB mounting and integration.
  • Stable and repeatable temperature-resistance characteristics for reliable system performance.
  • Optimized performance-to-cost ratio for volume applications and prototyping.

Applications

  • Temperature monitoring and control in 3D printer hotends and heated beds.
  • Environmental sensing for weather stations and HVAC system feedback loops.
  • Battery temperature monitoring in power banks and energy storage systems.
  • Temperature compensation for precision analog circuits and oscillator stability.
  • DIY electronics projects and educational kits for learning thermal sensing principles.

Frequently Asked Questions

What is the resistance value and tolerance of this thermistor?

This is a 100 kΩ NTC thermistor at 25°C with a standard B-value of 3950K. It has a resistance tolerance of ±1%, providing a high degree of accuracy for temperature measurement and compensation circuits.

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

The thermistor is typically used in a voltage divider circuit. Connect it in series with a fixed resistor (e.g., 100kΩ) between Vcc and GND, and read the analog voltage at their junction with an MCU's ADC pin. Use the Steinhart-Hart equation or a pre-calculated lookup table to convert the resistance to temperature.

What are the advantages of the epoxy resin-coated wire leads?

The epoxy resin coating provides a firm seal around the wire leads, offering enhanced moisture resistance and mechanical durability. This makes the sensor suitable for applications exposed to humidity or requiring long-term reliability, such as in environmental monitoring or appliance control.

Can the electrical parameters or wire specifications be customized?

Yes, HaiWang offers customization for parameters like resistance value, B-value, lead wire type, length, and connector termination. This is ideal for OEMs and engineers designing products with specific form-factor or performance requirements.
