电子控制部件,尤其是用于航空、汽车、勘探、采矿等室外移动设备上的电子控制部件受环境温度影响的问题是人们普遍关心的问题.由于环境温度变化幅度大,晶体元件对温度又比较敏感,因而寻找它们的变化规律并寻求各种方法以减少温度对元件性能的影响是电子线路设计者的一项重要工作.就以晶体管放大器为核心的电子控制部件而言,由于电阻和电容的温度系数比较小,一般在10一弓左右,而二极管、稳压管又比较简单,因此
Electronic control components, especially those used in outdoor mobile devices such as aviation, automobile, exploration, mining, etc., are affected by the ambient temperature, which is a common concern because of the wide range of ambient temperature changes, Sensitive, so looking for their variation and looking for ways to reduce the impact of temperature on the performance of the device is an important task for electronic circuit designers.To the transistor amplifier as the core of electronic control components, the resistance and capacitance The temperature coefficient is relatively small, generally about 10 bow, and diodes, regulator is relatively simple, so
