Tape-Wound Bobbin Cores

These tape-wound bobbin cores can be used in special low frequency transformer and inductor designs, magnetometers, and current-sensing transformers.

PWI’s tape wound cores are unique in their core memory due to their switching speed and magnetic memory characteristics, which are achieved in our manufacturing processes.
