When we buy wireless transceiver modules, we will find that many wireless transceiver module manufacturers will be "industrial-grade" to do as part of the product title, then we know what the meaning of this industrial-grade representative?
Industrial grade in the field of electronic components is a hierarchical mechanism, belongs to the middle of the ranking, the specific level is divided into: military grade, industrial grade, commercial grade. We may not be clear, what is the difference between commercial grade, industrial grade and military grade? Generally, military grade is the best performance, followed by industrial grade, and commercial grade is inferior to industrial grade. The best way to differentiate between the three is by temperature.
Military grade: -55 ℃ ~ +125 ℃, as the name suggests, military grade are generally used for military electronic components, so the requirements will be particularly stringent, mainly used in missiles, airplanes, tanks, aircraft carriers and other military fields, the military inside the electronic components, any part of the take out, is the most advanced, leading technology, expensive, high precision; military-grade electronic components are generally leading Industrial grade for several years.
Industrial grade: -40 ℃ ~ +85 ℃, industrial-grade electronic components are generally used in a variety of harsh industrial environments, such as: oil fields, mines, etc.; industrial-grade electronic components than the military-grade grade is slightly lower, the price of the second, the precision will be a little worse.
Commercial grade: 0 ℃ ~ 70 ℃, commercial grade electronic components are generally applied to some of our common electronic products, such as: cell phones, computers and other common household appliances, the most inexpensive and most common, but also one of the most contact with us.
In addition, due to the rapid development of the automotive industry, behind the emergence of a new level of electronic components: car level -40 ℃ ~ +125 ℃, car level are generally applied to the car on the tight components, due to the process of automobile startup, it will produce high heat, so in terms of high temperature, it will be higher than the industrial level, and at the same time the price is higher than some of the industrial level.
Temperature is just to provide us with a simplest way to distinguish, there is a standard of data that allows us to determine their level very intuitively, in addition we can also be based on their process, material selection, circuit design and so on to determine whether it is in line with a certain level. Commercial grade, industrial grade, automotive grade, military grade temperature differences, often also due to the use of different materials and even different processes lead to, due to the different materials, the finished electronic components may be different performance, life, anti-jamming ability.
Today to popularize what is the purpose of industrial grade, is to help you in the purchase of wireless transceiver modules before, according to the background of the project (military, automotive or industrial, commercial, etc.), choose a different level of wireless transceiver modules, otherwise when bought to the inappropriate project, the loss of the cost of not to mention, but also a lot of wasted time.
