Wurth Electronics introduces their Q+ line of products. These parts are manufactured to exceed AEC-Q200 qualifications. Internal structures of the products in the Q+ products portfolio are very different from conventional ones. For example, the wire connection between coil wire and component is not made with a conventional solder joint, but by means of a welding process. Another example is ferrite sleeves; compared with the conventional industry article, the surface form is optimized and this considerably simplifies the routing of lines.
