Alloy Powder Cores are soft ferromagnetic cores made from ferrous alloy powders, after insulating , mixed pressed with in-organic binder then annealing in high temperature. Alloy Powder Core materials are pressed with an in-organic binder, so there is no thermal aging. Alloy Powder Cores are distributed air gap cores that are primarily used in power inductor applications, such as switched-mode power supply (SMPS) output filters, differential inductors, boost inductors, buck inductors, and flyback transformers. Alloy Powder Core materials are high resistivity, low hysteresis and eddy current losses and excellent inductance stability under both DC and AC conditions.
Iron Powder Cores
Iron powder core is a soft ferromagnetic material based on pure iron or carbonyl iron powder; mixed with binding material and pressed to form the surface is coated with insulation material. Iron powder core has a high magnetic flux density (14000Gs), so it will not be saturated under high magnetic field. It has a very good DC superimposed characteristic.
Toroidal Alloy Powder Cores
Alloy Powder Cores are soft ferromagnetic cores made from ferrous alloy powders, after insulating, mixed pressed with in-organic binder then annealing in high temperature. Alloy Powder Core materials are pressed with an in-organic binder, so there is no thermal aging.
