Description

The HaiWang MF58 NTC thermistor is a high-reliability temperature sensor designed for precision measurement and control applications. Utilizing a Negative Temperature Coefficient (NTC) ceramic element, its resistance decreases predictably with increasing temperature, following the specified 3950 B-value curve. The sensor is hermetically sealed within a glass encapsulation, protecting the sensitive element from moisture, chemical exposure, and mechanical stress, thereby ensuring long-term stability.

This sensor is engineered for seamless integration into electronic control systems, providing a fundamental analog input for temperature monitoring circuits. Its fast response time and wide operating range make it ideal for dynamic thermal management in power supplies, battery packs, and heating/cooling systems. The robust construction and standardized lead spacing allow for reliable wave-soldering and automated assembly processes.

Frequently Asked Questions

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

This HaiWang MF58 thermistor has a nominal resistance of 200 kilo-ohms (200KΩ) at the reference temperature of 25°C. Its B-value, which defines the resistance-temperature curve, is 3950 Kelvin (typically specified between 25°C and 85°C). These parameters are essential for accurately calculating temperature from the measured resistance.

How accurate is this sensor, and what does the 1% tolerance mean?

The sensor features a resistance tolerance of ±1% at 25°C. This means the actual measured resistance of any unit will be within 1% of the stated 200KΩ value, ensuring high consistency and measurement precision from sensor to sensor. The B-value tolerance is also typically tight, contributing to overall system accuracy.

Why is the glass encapsulation important for an NTC thermistor?

The glass encapsulation provides a hermetic seal, protecting the sensitive ceramic NTC element from moisture, humidity, and chemical contaminants. This dramatically improves long-term stability and reliability, especially in harsh environments with high temperature and humidity swings, preventing drift and failure.

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

The thermistor is a passive, two-terminal device. You typically connect it in a voltage divider circuit with a known fixed resistor, then read the resulting analog voltage with an ADC pin on your microcontroller (Arduino, ESP32, etc.). You must then use the Steinhart-Hart equation or a lookup table, utilizing the 200KΩ and 3950 B-value, to convert the resistance reading into temperature.

What are the typical mounting considerations for this component?

The radial lead package is designed for through-hole PCB mounting. Ensure proper lead spacing on your board layout. For accurate temperature measurement, consider the thermal coupling between the sensor and the object you're measuring; using thermal paste or ensuring good physical contact can improve response time and accuracy.
