(NTC)Introduction to thermistor

At present, the application environment of the market is more diversified than before, and thermistor is a more common temperature sensor measurement and control components, with high temperature measurement accuracy, high sensitivity, good reliability, low cost, long service life and other characteristics, widely used in aviation, Marine and civil fields. With the continuous progress of electronic industry and information technology, modern electronic information system is developing towards microminiaturization and monolithic integration. In order to meet the needs of market diversification, our company specially launched MF72 negative temperature coefficient thermistor, negative temperature coefficient thermistor, also known as NTC thermistor, is a kind of resistance value decreases with the increase of temperature of a sensor resistance. Widely used in a variety of electronic components, such as temperature sensors, compound fuses and automatically regulating heaters. Follow the small series to understand our NTC thermistor products.

1. Working principle of NTC thermistor: NTC stands for Negative Temperature Coefficient, which means Negative Temperature Coefficient. It refers to semiconductor materials or components with large Negative Temperature Coefficient. It is made of manganese, cobalt, nickel, copper and other metal oxides as the main materials, using ceramic technology. These metal oxide materials have semiconductor properties because they conduct electricity in a way similar to semiconductors such as germanium and silicon. At low temperature, the number of carriers (electrons and holes) of these oxide materials is small, so their resistance value is high; As the temperature increases, the number of carriers increases, so the resistance decreases.

2. Application scope:

► Power conversion
