What are the principles to follow when choosing electronic components?

With the rapid development of science and technology, the manufacturing technology of components is also improving day by day. From the earliest several components to the present, there are various and complete types, which are developed by the continuous research and development of scientific and technological personnel. However, in the face of more and more types of components, many friends who are just getting started are facing an important question: what principles should be followed when choosing electronic components?

1. The application environment, performance index, quality level, etc. should meet the product requirements.

2. Standard components with stable quality, high reliability and long life cycle are preferred. Selection of discontinued or soon-to-be-discontinued components is not permitted. Beware of non-preferred components, non-standard components and newly developed components.

3. Select components from reputable manufacturers. Priority is given to components that are continuously produced, supplied in time, and supplied through multiple channels.

4. Define the meaning of the model mark of the components, and provide the complete component model.

5. Seeds, specifications and manufacturers should be compressed to the greatest extent, which is conducive to procurement and management.

When choosing electronic components, we should not blindly pursue cheap prices or purchase convenience, because components play an important role in PCB circuit boards and are one of the key elements of PCB board making.
