MH&W International Corporation offers a large range of Nanocrystalline NANOPERM® toroidal cores for common mode chokes. The main requirement on a EMC filter choke is high impedance. Useful characteristics of NANOPERM® are high permeability of up to a factor of 10 over ferrite, higher saturation induction, and extended working temperature up to 180°C. There are significant …
Due to the unique combination of excellent soft magnetic properties, nanocrystalline material is becoming increasingly more important, and will help to further improve tomorrows advanced power electronic systems. Applications like energy generation, energy distribution, energy measurement, and finally energy management. These applications will become more efficient, reliable, lighter, smaller, and smarter compared to existing designs …

Check out this interview from PCIM Europe 2011. Magnetec’s Marketing Director, Helmut Doenges, explains how the company is consolidating its leadership and delivering high performance products and service to its customers.
New NANOPERM® LM cores (µnom = 1.000, 2.000, 4.000 and 8.000) from Magnetec are very much advantageous in EMC filters for applications with a high amount of asymmetric interference current (e.g. inverter drives) compared to the established Ferrite materials. Main advantages: 3x higher Saturation flux density Bsat at the same Permeability level Small build volume …
The new current transformers from MAGNETEC, featuring NANOPERM® alloy core for high-precision readings plus improved tamper-proofing, can be combined with MAGNETEC’s magnetic shielding designs to form an ideal system solution for a broad range of anti tampering metering applications. The combined advanced features of both current transformer and adapted magnetic shielding offer a so far …
It is one of the most up-to-date topics within the Solar Power Industry to improve the efficiency of that complex process of energy conversion. Every single tenth of a percent is welcome – although > 90 % is already state-of-the art for modern DC/AC converters. Following this target, more and more producers of photovoltaic inverters …
For AC-type RCCBs that are sensitive to sinus exciting currents, toroidal cores made of Permalloy-type materials are used for decades. The application of nanocrystalline alloy NANOPERM in RCCBs were limited to a region where the special annealing cycle leads to flat or round ferromagnetic hysteresis loop with a remanence ratio smaller than 0,7 with a …
So far, nanocrystalline cores could not be used in applications with significant DC preload because they saturate early due to their high permeability level (> 18,000), which gives only an advantage in non DC applications. MAGNETEC now offers high saturation cores which enter into a low permeability range of typically 2,000 – 8,000 which was …
The ferrite industry has been affected by an extreme shortage of product in 2010. This is primarily due to an increase in ferrite consumption in Asia. We have seen ferrite manufacturers either discontinue their 15K permeability ferrite or highly restrict the manufacturing of this extreme material. (15K perm material is very difficult to make and …
