How to choose electronic components?

Designing electronic products - where to start?

In the initial phase of the project, particular attention should be paid to the selection of appropriate components. Choosing the right components is one of the most critical aspects of product design. Potential production interruptions depend on them. How to do it? There is no universal recipe that will apply to each of the projects. There are, however, some tips that will make this process much easier. In today's article, we will focus on them.


Make a list of all the items you will need. Enter the critical parameters for a given product right away. Consider whether you care more about compact size, ease of production or maybe the price will be the criterion? Will it be important for the project to be the most electrically efficient or with few components? There are many such questions - you should prioritize and choose the ones that will work best. A lot also depends on the conditions in which your project will be created. For example: when choosing a resistor for a LED diode, you don't have to pay much attention to its tolerance. In turn, when choosing a resistor for a precise divider, it should already be taken into account.

Product documentation

Each item comes with documentation that provides information about the product. Please read it carefully before selecting any components. Each parameter that is included in it is important - if it were not, it would not be there. Documents such as the application notes provided by the manufacturer help to understand exactly how it works. We sometimes come across test results and evaluations of certain items - thanks to them it will be easier to choose the best one. Some manufacturers provide additional materials, such as industry-specific reference designs, software tools that help the user evaluate the performance of a component configured for their own design before constructing it. Such solutions contribute to the shortening of the study and partially eliminate errors.


As we mentioned in the introduction - there is no universal solution. First of all, you should decide what to expect from a given component. Check the conditions under which it will work in the following part. On the basis of this and the generally available product documentation, specific materials are selected. It is a tedious task for someone who does not know the inside out of the market. In such a situation, it is best to refer to a company that has many years of experience in this area - a company like ours. We cordially invite you to contact us by e-mail and telephone.
