We carry a range of ferrite cores from Magnetics. These soft magnetic ferrite cores are created using manganese, zinc and iron to create a ferromagnetic compound. Ferrite cores are known for their high permeability, low disaccommodation and good temperature properties. Because they have low losses at high frequencies, ferromagnetic materials are popular in transformers, inductors and switched-mode power supplies. Magnetics ferrite cores are available in an assortment of materials, with permeability ranging from 900µ to 15,000µ. We carry ferromagnetic materials in a variety of geometries including toroids, e-shapes and pot cores.

Magnetics Ferrite Pot Cores

This core's shape is optimal for adjusting the ferrite structure to meet very specific application requirements. Typical applications of ferrite pot cores include power transformers, power inductors, filters, both broadband and narrow transformers, telecom inductors and more. Pot core designs provide an optimal ratio of volume to surface area, creating the opportunity for maximum inductance with minimal space and fewer hot spots than with other core designs. Pot cores offer good temperature stability, and their unique geometry protects from stray magnetic fields or effects from other surrounding circuit elements.

Magnetics Ferrite Uncoated Toroid Cores

The uniform cross-sectional area of ferrite toroids eliminates any air gaps and creates the optimal features for designs that require high magnetic efficiency. Outside diameters of Magnetics ferrite toroids range from 2 mm to 140 mm, and permeabilities range from 900µ to 15,000µ. Magnetics’ high permeability ferrite toroids are typical for use in common mode chokes, EMI filters, broadband transformers, pulse transformers and current transformers. These cores are uncoated, and applying your own various coatings will determine winding ease and voltage breakdown. Magnetics ferrite toroids are available in nine materials: L, R, P, F, T, J, W, C and M.

Magnetics Ferrite E Core

Ferrite E cores are a less expensive alternative to pot cores. They can be pressed into different thicknesses to adjust the cross-sectional area, and are easy to assemble and wind. They can be mounted in different directions and can be used for low profile mounting. Unlike pot cores, however, E cores do not self-shield. Magnetics ferrite E cores are available in E65, E80 and E100 sizes. E cores are most commonly used for differential, power and telecom inductors, as well as broadband, power, converter and inverter transformers.
