The power module is a kind of "power adapter", which gathers all the required components and places them on the same chip or circuit board. It is widely used for switching equipment, mobile communication, even optical transmission, router and other communication and aviation fields. So many accessories, many engineers don't know how should choose to suit their own power supply module, if select product level too high or too low will cause some surprises happen to daily use, in order to avoid accidents, today is to introduce the types of modules, we can according to their own needs to choose and buy.

1, according to the use of objects can be divided into what level?

It can be divided into aerospace grade, aviation grade, military grade, industrial grade, civil grade, consumer grade and so on, which are generally used in their respective related fields and need to be selected according to their own use environment and conditions.

2. What is the ranking order?

The highest grades are, of course, aerospace, which is typically made of ceramic substrates, and petroleum, which is made of SIC devices. Then there is the aerospace grade, which is identical to the aerospace grade except that there is no radiation resistance requirement. The next ones are general military, industrial communications, and then the more everyday ones. Can also be divided according to the level of lightning protection, according to the different minefield equipment pressure value and lightning into the ground to be divided, if the site of the electromagnetic requirements more rigorous, also need to consider the factor of lightning wave reflection.

Above is to have a little knowledge about the power supply module, the right choice for your production environment and the requirements of the module is the most appropriate, module also need to find a brand effect of choose and buy, buy the big company of good reputation, product quality and after-sales service, are small producers have more security than the unknown.
