I tried to buy an electronic component over the internet and when I accessed the website, a message indicated that the component cannot be sold in my countryl. What is the reason?"
Unfortunately, for security reasons, due to the need for approval by entities in the case of medical equipment, there are components and electronic devices that cannot be sold in all countries. Thus, if the reader intends to buy some type of component to be placed in an equipment to be manufactured, he must check if its use is allowed. Mouser Electronics, for example, when making the purchase and giving origin your country already informs if it is possible or not to use the component.
