Magnetics Adds New Powder Cores and Nanocrystalline Cores

Magnetics, a supplier of precision soft magnetic components and materials to the electronics industry, has come out with new series of powder cores and nanocrystalline cores. Shown above are the company’s new EER shape powder cores with geometry that provides excellent space utilization for improved component efficiency, energy storage capacity, and power by volume. 

hen compared with toroidal cores, they are designed to allow for easier helical winding, thus reducing overall cost, and easier mounting. Sized at 25.5 mm and 40 mm, or custom height, they come in the company’s Kool Mu, XFlux, and High Flux materials. 

LP shape powder cores 

Magnetics also now offers LP shape powder cores in size 36 x 24 mm, adding to existing outder diameter sizes 23 mm, 25 mm, and 42 mm. The planar design of LP cores helps to maximize inductor efficiency and are available in 26 and 40 permeabilities. 

Nanocrystalline core lineup has also been expanded 

The new nanocrystalline cores are designed for applications such as common mode chokes and currently available in toroids or split cores from 5 mm to 145 mm. 

Due to the high permeability of nanocrystalline cores, chokes can be smaller in size and handle higher current, notes the company. When compared to ferrite cores, nanocrystalline cores provide a wider operational temperature range and significantly higher impedance at high frequencies. Ideal applications for the nanocrystalline cores include AC current transformers, zero phase current transformers, DC immunity current transformer, Hall Effect sensors with cut current transformer cores. 

Based in Pittsburgh, PA, Magnetics operates globally, specializing in research, design and production of powder cores, ferrite cores and tape wound cores for applications such as chokes, inductors, filters, transformers and power supply components for use in alternative energy, uninterruptible power supplies, telecommunications, aerospace, military, medical and other electronics systems. See
