Ferrite Materials: Ferrite Cores
Magnetics® soft ferrite cores are an oxide made from Iron (Fe), Manganese (Mn), and Zinc (Zn) which are commonly referred to as manganese zinc ferrites. They have a low coercivity and are also known as soft magnetic ferrites. Because of their comparatively low losses at high frequencies, they are extensively used in switched-mode power supply (SMPS) and radio frequency (RF) transformers and inductors. Ferrite cores for the high frequency power supply and high quality communication markets are produced in a variety of shapes and sizes for inductors, pulse transformers, high frequency transformers, and noise filters. Notable characteristics of Magnetics ferrite materials are high permeability, good temperature properties, and low disaccommodation. Magnetics offers ten materials. The materials range in permeability from 900µ to 10,000µ and are available in a variety of geometries including toroids, shapes and pot cores. Hardware accessories such as bobbins, printed circuit bobbins, clamps, mounts and headers are also available.
