Precautions for purchasing electronic components are as follows:
1. Check the production date. The production date of the new product should be within the last two years.
2. Check whether the pins of the components are rusty and dull, and the pins will gradually oxidize due to too long time, and then lose luster.
3, if its price is particularly cheap, you need to pay attention to whether it is genuine or not.
4, retail is more expensive: so it is best to buy more than one component at a time.
