Ferrite Core
Ferrite Core, EMI soft ferrite core, SMD ferrite core, MnZn ferrite core, Various Styles Ferrite Cores for TRANSFORMER and INDUCTOR
Ferrite Core – Ferrites that are used in transformer or electromagnetic cores contain nickel, zinc, and/or manganese compounds. They have a low coercivity and are called soft ferrites. The low coercivity means the material’s magnetization can easily reverse direction without dissipating much energy (hysteresis losses), while the material’s high resistivity prevents eddy currents in the core, another source of energy loss. Because of their comparatively low losses at high frequencies, they are extensively used in the cores of RF transformers and inductors in applications such as switched-mode power supplies and loopstick antennas used in AM radios.
The most common soft ferrites are: MnZn ferrite (Manganese-zinc ferrite). MnZn have higher permeability and saturation induction than NiZn. NiZn ferrite (Nickel-zinc ferrite). NiZn ferrites exhibit higher resistivity than MnZn, and are therefore more suitable for frequencies above 1 MHz. For applications below 5 MHz, MnZn ferrites are used; above that, NiZn is the usual choice. The exception is with common mode inductors, where the threshold of choice is at 70 MHz.

HSMAG Ferrite Cores – 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 15,000µ 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.
