Ferrite Cores: Types, Properties and Applications




Ferrite cores are one of the most common and versatile types of magnetic cores for RF circuit applications. They are made of ceramic materials that contain iron oxide and other metal oxides. They have high permeability, high resistivity, low losses and good temperature stability. They are suitable for a wide range of frequencies, from 1 kHz to several GHz.


There are two basic groups of ferrite cores: nickel-zinc (NiZn) and manganese-zinc (MnZn). NiZn ferrite cores have low permeability (20 to 800) and high resistivity. They are ideal for medium frequency inductors and wideband transformers up to 50 MHz. They also offer excellent RFI suppression from 40 MHz to 400 MHz. MnZn ferrite cores have high permeability (above 800) and low resistivity. They are ideal for low frequency antennas and switched mode power conversion transformers from 1 kHz to 100 kHz. They also offer good RFI suppression from 20 MHz to 400 MHz.

Iron Powder Cores: Types, Properties and Applications




Iron powder cores are another popular type of magnetic cores for RF circuit applications. They are made of iron particles that are coated with an insulating material and compressed into a toroidal shape. They have low permeability, high saturation flux density, low losses and good temperature stability. They are suitable for a wide range of frequencies, from 50 kHz to 500 MHz.


There are several types of iron powder cores, such as carbonyl iron powder (CIP), sendust (Kool Mµ), molypermalloy powder (MPP), high flux (HF) and super flux (SF). Each type has its own advantages and disadvantages depending on the frequency, power level and application of your RF circuit. CIP cores have the lowest losses but the lowest saturation flux density. Sendust cores have low losses and moderate saturation flux density. MPP cores have high losses but high saturation flux density. HF cores have moderate losses and high saturation flux density. SF cores have high losses but very high saturation flux density.

  • Q3: How can I find out the AL value of a core that is not listed in the book?



  • A3: You can find out the AL value of a core that is not listed in the book by using the formula AL = L / N^2, where L is the inductance in microhenries and N is the number of turns. You can measure the inductance of a core with a multimeter or an LCR meter. Alternatively, you can contact Amidon and ask them for the AL value of the core you are interested in.



  • Q4: How can I measure the permeability or Q factor of a core that I have at home?



A4: You can measure the permeability or Q factor of a core that you have at home by using an LC meter or an impedance analyzer. You will need to wind a known number of turns on the core and measure its inductance and resistance at a given frequency. Then you can use the formulas µ = AL * N^2 / A and Q = 2 * pi * f * L / R, where µ is the permeability, AL is the AL value, N is the number of turns, A is the cross-sectional area of the core, Q is the Q factor, f is the frequency 71b2f0854b
