Nickel zinc magnetic collar Overview: annular magnetic rings main raw materials: iron oxide (Fe2O3), zinc oxide (ZnO), NiO (NiO), copper oxide (CuO), manganese carbonate (MnCO3) were highest content of 60%, 15%, 10%, 10%, 5%. After the ingredients, forming, using furnace sintering. Annular magnetic rings can be divided into the high magnetic permeability material, conventional materials and low permeability material. Magnetic permeability of 1000 or more commonly called the high permeability material, the magnetic permeability 200-1000 known conventional materials, the magnetic permeability of 200 or less is called a low permeability material. Typically, the lower the magnetic permeability material, the wider the frequency range; the higher permeability material, the narrower the frequency range. For example: μi = material 15 is suitable for applications above 100MHz, while the material μi = 1MHz 1500 applies only to the following situations. Nickel zinc magnetic ring Applications: Due to the high-frequency magnetic ring, broadband, high-impedance, low loss characteristics, more and more attention in recent years, becoming in the high frequency range (1-300MHz) within the widest application, performance Excellent ferrite materials. Toroidal magnetic products used in computer monitors LCD TVs, electric cable, flat type cable, communications equipment lines, interference filter lines, electrical cable, power cord, USB cable, home appliances, cables, and other types of machinery and equipment Series interference effects.
