Nanocrystalline Magnetic Bead Description
Nanocrystalline magnetic bead is smaller, reduces cost, saves energy, and saves space, compared with the boxed bead. Nanocrystalline magnetic beads are suitable for miniature filter common mode inductor, ISDN network transformer, network filter, EMC filter, IGBT / Mosfet drive transformer, HD camera signal transmission transformer/filter.
