I recently preformed a safety evaluation of a product made in the far east which contained a suspicious looking rf line filter. Instead of the nice silkscreened markings showing the company name, numbers and a schematic of the filter components, it just had a basic printed label. When I removed the filter and turned it over I found that the case was not soldered but just spot welded in four spots.
Are line filter companies cutting corners to save money or might this filter be a counterfeit? The filter manufacturer's website doesn't show this model filter (anymore?) but you can buy them from several online electronic component companies. Has anyone run across counterfeit components and is this something we need to keep an eye out for? My biggest concern is with safety certified components which smaller companies like ours have to purchase through distributors who get them from who knows where. Is this a real concern or am I just being paranoid?
