I've recently seen some TO-220 FETs that appear to be counterfeit parts that have had the marked area resurfaced and remarked with a false part number. I don't know much about semiconductor manufacturing, and I just want to know if there is a type o

This I have heard from (2) different sources. Fuji feeders for CP series machines are now being counterfeited in China and are being sold as original. They will in all appearences look completely legit in original boxes and with Fuji bar-codes. Once
