The ferrite core is a variety of magnetic core from ferrite that has winded with electrical transformer and some other components like inductors. This is mostly preferred for high magnetic permeability combined with low electrical conductivity. The major reasons of using low losses occur in high frequencies that are extended to using RF transformers and inductors in applications like SMPS and ferrite loopstick antennas for receiving signals in AM radios..
Generally, the ferrite cores has combined with manganese zinc ferrites that means an oxide form from Iron (Fe), Manganese (Mn) and Zinc (Zn). These ferrite cores is having low coercivity so this called as soft magnetic ferrites due to low
The powder cores has assigned air gap cores, which is mainly carried power inductor application especially the SMPS output filter is called one of the DC inductors also combined Magnetic powder core with differential inductors, boost inductors flyback transformers and buck inductors. Magnetic powder core has following lot of significant factors such as , high resistivity, low hysteresis and eddy current losses. Furthermore, the inductance stability is acceptable in the AC and DC conditions. Different cores are available but its size may be varied so he cores has been differentiate in the height levels. The cavities are combined with the core height levels due to the dies may occur.
