The circular of powder core type
The types of the circular of powder core: iron nickel molybdenum ( MPP) Magnetic powder core - - - - - - - - - - - - - Iron nickel molybdenum ( MPP) The Q value of the magnetic powder core, and it is core loss minimum. MPP iron nickel molybdenum powder core temperature performance and communication ( AC） The most stable flux performance. It has the widest permeability optional range, is a switching power supply in dc ( DC) Best choose materials, output filter inductors in MHZ class of applications is very applicable and MPP iron nickel molybdenum powder core is the most suitable for precision audio frequency tuning circuit, high Q value filter, load coil, rf ( RFI） Filter and many other precision inductance applications of high flux iron nickel ( 你好, FLUX) Magnetic powder core - - - - - - - - - - - - - High magnetic iron nickel of HI - FLUX is a kind of magnetic powder core containing 50% 50% nickel and iron are distributed air-gap magnetic powder core. HF magnetic iron nickel powder core has up to 13000 gauss saturation magnetic flux density value, its loss value is significantly lower than pure iron powder core. Is modulation inductor, switch power supply circuit noise filter, the choice of pulse transformer and flyback transformer. Especially in large dc current situation, the use of HF can effectively reduce the size of inductor, magnetic powder core, in turn, reduce the total cost. Iron silicon aluminum ( 铝硅铁粉) Magnetic powder core - - - - - - - - - - - - - Iron silicon aluminum ( 铝硅铁粉) Magnetic powder core is a kind of modified iron silicon aluminum material, for it has been designed for iron powder cores, core loss is lower, and the energy storage capacity than iron nickel molybdenum ( MPP) Magnetic powder core. SENDUST iron silicon aluminum magnetic powder core is energy storage and filtering inductance used in switching power supply core ideal choice. Low core loss performance can make SENDUST iron silicon aluminum magnetic powder core than the similar size of pure iron powder core has a lower temperature rise under high frequency. At the same time it's dc bias magnetic field ( 直流偏置) Performance is better than similar permeability is better and size of pure iron powder core.
