MH&W has put together several combinations of planar cores that are in common use in the NAFTA areas. These planar cores are in stock and available for sales and modifications if needed. The list of cores and the related Drawings are:
MH&W International announces the availability of TDK EFD Cores to its line-up of flat pack cores. 15 years ago, TDK developed the EPC core line to serve the need of DC/DC converters requiring low profile transformers. Today we are adding to the EPC line the EFD line of ferrite cores in the most popular sizes …
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 …
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 …
Recently, MH&W entered into a partnership with a Japanese company to act as our agent in Japan to locate bobbins and hardware and handle all negotiations as well as export control. We can now announce that with our partnership, MH&W will have access to most of the original TDK tooling. We have identified the tooling …
Recent Design Win with Major Wind Nacelle Manufacturer Celebrated in Mahwah MH&W International, Corp. is celebrating yet another design win by extending the life of bearings in wind turbine generator drives. A major manufacturer of wind turbine generators has recently awarded MH&W International, Corp. a contract to supply Magnetec Cool Blue Nanocrystalline cores for all …
TDK-EPC (magnetic group of TDK Corporation) has announced the intention to discontinue the manufacture of all bobbins and mounting hardware currently being supplied by MH&W International Corp. MH&W will accept orders for the bobbins and mounting hardware as a last time buy. All orders must be submitted to MH&W no later than June 10, 2010. …
Magnetec has announced a tape wound core for current transformers capable of handling a DC component (IEC 1036). These tape wound cores are made from Nanocrystalline material to Magnetec’s patented annealing process. These special cores for current transformer are low permeability cores which has advantages such as: Small Amplitude error which is required for Electronic …
