Long-life NTC thermistor, is the NTC thermistor understanding of the promotion, emphasizing the importance of resistance life. NTC thermistor is the most important life, in a variety of high precision, high sensitivity, high reliability, ultra-high temperature, high pressure test, it is still a long time stable work. Lifetime is an important property of NTC thermistor, which is dialectically related to other parameters such as precision and sensitivity. A NTC resistor must first have a long life to ensure the performance of other performance, and other performance excellence depends on the production process to reach a certain level of technology, which makes the long life of NTC possible. Many high-tech electronic products, in ultra-high temperature, ultra-high voltage and other harsh conditions, the need for thermal resistance to play a stable temperature control, temperature measurement function, most manufacturers blindly pursue NTC thermistor accuracy, sensitivity, drift value and other conventional performance of the stable play, ignoring the resistance life, lead to the NTC can not work for a long time and affect the use of electronic products. In this way, all the precision, sensitivity, high temperature resistance and so on, become meaningless.

In various AC and DC circuits, most components have positive temperature coefficient characteristics, such as coils, LCD displays, transistors, quartz oscillators, etc. When precision circuits or components that are particularly sensitive to temperature are affected by temperature, zero point temperature drift or sensitivity drift with temperature will occur, causing phenomena such as signal distortion, speaker sound out of tune, quartz oscillator frequency fluctuations, and unstable performance. In order to obtain a good working condition in a wide temperature range and keep the resistance stable, one or more NTC thermistors are used in conjunction with it. The negative temperature characteristics of the NTC thermistor can offset the temperature effect on the components in the circuit. Influenced by characteristics, it plays the role of temperature compensation, so that the circuit can work stably and reliably in a wide temperature range.
