Iron coil : Iron core, which is made from pure iron powder, is characterized by perfect magnetic bias and well performance under the temperature range -65125 but large core loss under high-frequency working environment. It is the economical and practical material for manufacturing EMI filter and passive PFC inductor, as well as chock of the switching circuit of low working frequency (50 kHz or less), active PFC inductor and the likes. Material iron core is widely used in switching power supply, computer motherboard, light modulator, UPS and other EMC fields. IRON coil 1.Inductance range : 0.1uH to 10000uH . 2.Suggested frequency : 3."26": 50Hz 100 KHz. "52": 50Hz 200KHz. "18"/"53" : 50KHz 700KHz. "8/90": 100KHz 2 MHz. Mn-Zn coil: 1.Power type: This type is generally known as Power material, its initial permeability is less than 3,000 ui (1,400ui3,000ui); 2.High-permeability type: This type is universally known as communication material for its high initial permeability(4,000ui15,000ui) and is widely used in communication power supply, power adapters, filters and other products. SENDUST coil: SENDUST is a kind of improved Fe-Si-Al materials. It was designed to replace pure iron core because of its little core loss and its larger energy storage compared to MPP magnetic core. It is characterized by its anti-vibration and high stability against temperature and humidity when working under the temperature -55125. SENDUST is the ideal material for energy storage of switching power supply and filter. Its low core loss enables lower temperature rise compared to the pure iron core of the same size. In addition, the DC bias of SENDUST works better than that of pure iron core of the similar permeability and size does. MPP coil: MPP magnetic core possesses the highest Q value and the lowest core loss among the various cores. It is characterized by the perfect stability against temperature and magnetic. Its wide range of permeability makes it the best material for the filter of DC switching power supply and applicable under the megahertz-class applied situation. Generally, MPP magnetic core fits the precise tuning circuit of audio equipment, high-Q filter, load coils, RFI filter and any other inductor of precision applied occasion most. Hi-Flux iron-nickelcoil: Hi-Flux iron-nickel core is made from 50 percent of nickel powder and 50 percent iron powder with distributed air gap. Hi-Flux magnetic iron-nickel core with up to 13,000 Gauss saturated magnetic-flux density value has much smaller loss than pure iron core. Therefore, it is the ideal material for modulating inductor of switching power supply, circuit noise filter, pulse-transformer and fly-back transformer (FBT). Especially the use of HF Iron-nickel core in the large DC current can effectively minify the inductor.
