With the development of science and technology, the types and functions of electronic components are becoming more and more perfect, and the branches are gradually expanding. However, selecting components also becomes a technical task. A lot of new people will take a lot of detours when they are just starting out in the industry or just designing PCB boards, and the losses will not be great. Today Xiaobian will bring you the selection of components. Basic principle, hope to give you some help ~

With the development of science and technology, the types and functions of electronic components are becoming more and more perfect. However, selecting components also becomes a technical task. Many small partners in the industry or design PCB board when they will take a lot of detours, eat very thanks to. Today Xiaobian will introduce to you the basic principles of component selection, hoping to give you some help ~

Principle of generality:

If the selected components have been widely used and verified, try to use less unpopular and biased chips to reduce development risks.

Principle of substitution:

Try to select components with more pin-to-pin compatible chip brands.

Principle of high cost performance:

In the case of similar function, performance and use, try to choose the components with better price to reduce the cost.

Principles of Sustainable Development:

Try to choose components that will not be discontinued for a foreseeable period of time.

Principles of resource conservation:

Try to use all the functionality and pins of the component.

Principle of convenience in purchasing:

Try to choose components that are easy to buy and have a short lead time.

Principle of upward compatibility:

Try to select components that have been used in previous products.

If you are familiar with the basic principles of selection of these components, you can rest assured and boldly choose components in accordance with these principles! Hope it helps you!
