Common electronic components are generally classified according to the use of temperature, radiation, anti-interference and so on. The grades are divided into the following 5 categories:
Commercial grade, industrial grade, automobile grade, military grade, aerospace grade.
Commercial grade -- the temperature is 0¡æ ~ +70¡æ. The common and frequently traded ones in the market, such as computers, mobile phones and household appliances, are basically commercial grade, with the cheapest price, the most common and the most practical.
Industrial grade -- temperature: -40¡æ ~ +85¡æ, a little lower than the military grade grade, the price is second, the precision is also a little bit worse.
Automobile industrial grade -- temperature: -40¡æ ~ 125¡æ, mainly used in the automobile precision components, use temperature requirements higher, more expensive than the industrial grade.
Military grade -- temperature: -55¡æ ~ +150¡æ, mainly used in missile, aircraft, tank, aircraft carrier and other military fields, military inside the electronic components, any part out, are the most advanced, leading technology, expensive, high precision.
Aerospace level -- temperature: -55¡æ ~ +150¡æ, aerospace level components are the highest level, mainly used in rocket, spacecraft, satellite and other aerospace fields, the use temperature is the same as military level, but on the basis of military level, anti-radiation and anti-interference functions are added.
