Magnetic powder core is a material that has an inherent distributed air gap. The distributed air gap allows the core to store higher levels of magnetic flux when compared to other magnetic materials, such as ferrites. This characteristic allows a higher DC current level to flow through the inductor before the inductor saturates. Magnetic powder cores are made of iron and some other material such as Si, Al or Ni. The particles are insulated from each other, mixed with a binder (such as phenolic or epoxy) and pressed into the final core shape. CODACA high current power inductor such as CSBX，CSBA and CPEX are made of magnetic powder core.
