Electromagnetic inference (EMI) considerations are increasingly important as electronic devices become more ubiquitous in of our daily lives. Our reliance on these devices has increased the performance requirements for electromagnetic compatibility (EMC) components like common mode chokes coils, which provide protection against incoming and outgoing high frequency noise.
They also protect electronic devices against high voltage pulse noises generated by spark discharge, etc. In switching power supplies, the waveforms are periodic, but they become non-periodic in the case of data lines used in telecommunications. That's where AMO Greentech (www.amogreentech.com) comes in. They are a 'Total Green Solution Provider'. Their core business is Renewable energy, Smart grid and Electronic Chokes to support an environmental friendly business model. AMO Greentech has developed, using advanced materials, the "Nano Ribbon"element, which is at the core of the choke product line.
They have a lineup of Choke products which have superior magnetic properties over other magnetic components on the market. The AMFN-Series (Nano Common mode chokes) are mainly used to provide attenuation of asymmetrical conducted interferences. AMFN series shows a higher insertion attenuation that is insertion damping, overall the wide-range of frequency. AMF Series magnetic cores of high permeability, which are made of co-based amorphous alloys, are now available. In addition, recently AMOGREENTECH launched new AMFN Series common mode choke cores, which are made of nanocrystalline alloy. The typical permeability of AMF and AMFN Series common mode choke is 80,000. Where permeability rates excede 80,000, AMOGREENTECH can provide higher level common mode chokes with AMF and AMFN Series flat loop cores to satisfy those requirements.
