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 losses may occur at high frequencies that is considerable usage in the SMPS and radio transformers and inductors.
The core losses is may calculating, it has predicted the size has identically. Gap losses are occur due to flux concentration in the core and eddy current is produced in the windings. The gap loss is extremely hiked overall losses if core is gapped. Moreover, many core geometries cross-sectional area is varying, local "hot spots" can proceed at points of low-level cross section. This is enhanced the permeability at the local areas which output has maximum losses at those points.
The different types of ferrite materials are available but familiar type of ferrites are nickel-zinc ferrite and manganese-zinc ferrite. Manganese Zinc is having maximal flux <a>toroidal transformer winding machine</a> density and its functional frequency range is less than 5MHz but excluded common mode inductors that impedance is good option up to 70MHz. the Nickel zinc ferrite having minimal flux density during manganese-zinc is higher. Then nickel-zinc ferrite is having high resistivity so it has functional frequency ranges from 2 MHz to some hundreds Mhz. impedance of nickel-zinc from 70Mhz to some hundred MHz.
