1 Product Line CatalogueSoft Ferrite Materials & Componentsfor Power, Signal and EMC ApplicationsMMG Canada LimitedMMG Companies:MMG-NeosidHuntingdon MagnetsMMG-North AmericaMMG-Neosid has been manufacturing magnetic Materials since its foundation in 1936and now manufactures an extensive range of soft Ferrite Components and are used in the Industrial, Computer, Telecommunications and Automotive/Aerospace industries and include both Mn-Zn and Ni-Zn Ferrite Components , thermo-set/thermoplastic formers and bobbins, and also offer a range of toroids and rods (leaded and un-leaded) in Iron and Nickel-Iron Powders including hard Ferrite magnets and resin bonded Neodymium-Iron-Boron magnets arealso available from Huntingdon Magnets - a division of MMG-Neosid, based sensitive to market changes.

2 MMG-Neosid is constantly developing new ferritematerials and component geometries to meet changing customer requirements and itis the experience gained from this that allows us to provide the very best of technicalsupport and assistance to our customers at all stages of their ISO 9002 accreditation forms the basis of our Quality Assurance Policy but wewould like to think we go beyond the scope of this and offer quality in every aspect ofthe way we do Company s policy is one of continuousimprovement and development and the right tochange Materials , designs, dimensions anddescriptive matter, etc.

5 Generally speaking, these loss factorsincrease with frequency at a steady rate, slowly atfirst and then rapidly increasing to overtake thefrequency rise. The point at which this acceleratedrate of increase of loss factors occurs depends uponthe composition and sintering conditions and mayvary between batches of frequencies well outside their normal range ofapplication, all ferrites exhibit high losscharacteristics, and are extensively used forsuppression GuideMMG ferrites are used in an extensive range ofproducts and applications. Electronics applicationsare constantly developing. Listed below is anapplications guide outlining the most popular use ofMMG material grades.
