PWI began manufacturing tape wound bobbin cores in 1999 when it purchased equipment and manufacturing rights from Friskem Infinetics. Tape wound bobbin cores can be used in special low frequency transformer and inductor designs, magnetometers, and current sensing transformers. These cores are utilized in applications where core memory is important. PWI’s tape wound cores are unique in their core memory due to their switching speed and magnetic memory characteristics that are achieved in our manufacturing processes. PWI produces all of the Fiskem Infinetics part numbers, as well our own product line. PWI is also capable of designing custom cores for specific applications.
