Applied Physics Systems (APS) supplies a wide variety of tape wound bobbin cores. Tape wound cores employ non-magnetic stainless-steel bobbins which are usually sleeved and painted to provide protection for the magnetic tape and voltage isolation between user applied toroidal drive coils and the bobbin.
Some low voltage applications (e.g. fluxgate magnetometers) do not require sleeving and painting, and we can provide these bobbin cores with shorter delivery times and at somewhat lower cost as compared to sleeved and painted cores.
