High efficient nanocrystalline POWER TRANSFORMER cores

Nanocrystalline material is extremely low-loss and thuspredestinated for the application „Power Transformer“. Our PT cores enable a very powerful design with very low lossesat high frequencies. As the epoxy coating rests directly on the strip material as the heat dissipation is optimal. Due to a low magnetostriction and very good RF characteristics, as well asthe excellent temperature resistance of the ribbon materialitself, you will get optimal conditions for a special design of your power transformer.
