Working Principle of the MC65G104B

The MC65G104B is a three-terminal NTC thermistor made with a silicon substrate and an oxide-nitride-oxide (ONO) barrier. Its working principle is based on the temperature-dependent resistance change of the thermistor due to negative temperature coefficient (NTC). As the temperature of the thermistor increases, its resistance decreases.

When the thermistor is connected to a direct current (DC) voltage source, a small current flows through it. This current is measured and then compared to a known resistance to determine its temperature. However, since the thermistor has a low resistance of its own, a resistor in series with it is usually used to convert the tiny current into a voltage that can be easily measured.

The MC65G104B thermistor also includes a range of features such as self-heating capability, which can heat up the thermistor to a specific temperature even when it\'s not specifically connected to a power source, and a temperature-compensation block, which helps to maintain the thermistor\'s accuracy even under extreme temperature variations.

Conclusion

The MC65G104B is a highly-accurate NTC thermistor that is suitable for a wide range of temperature sensing applications, from automotive to medical. Its fast response time, tight tolerance, low hysteresis loss, and self-heating capability make it a versatile, easy-to-use, and reliable temperature sensing solution.
