Ferrite core inductors are made for higher frequencies. The ferrite core is a non-conductive ferri-magnetic material which prevents eddy currents from flowing through it. The ferrite formulation is xxFe2O4 with the xx representing various types of metals.

what is iron core inductors
To make a 100uH inductor, you would typically start with a core material such as ferrite or powdered iron. Then, you would wind a specific number of turns of wire around the core, calculating the number of turns based on the desired inductance value (in this case, 100uH). The formula for calculating inductance is L = (N^2 * μ * A) / l, where L is inductance, N is the number of turns, μ is the permeability of the core material, A is the cross-sectional area of the core, and l is the length of the coil. After winding the wire, you would typically encapsulate the inductor in a protective casing.
If the circuit is undriven, there is no power, so inserting a core does nothing. In general, however, inserting a core into an inductor increases its inductance. Depending on the circuit, that lowers the resonant frequency.
The electrical abbreviation ( UH ) is a measure of inductance , as in a ferrite transformer core , inductors , choke etc. .
A ferrite core inductor with two 47 mH windings. An inductor usually consists of a coil of conducting material.
Ferrite bead is a lossy inductor.When the frequency is high the Ferrite bead purely acts as a resistance so high speed noises are absorbed by the FB and it dissipate in the form of heat. Based on the current rating,cross over frequency the ferrite bead should be select ANSWER: A ferrite bead is a powder core if a line is wrapped on it that will eliminate RF signal externally injected into the line to interfere with the circuit that the line is going to it. The selection is arbitrary until it does the job. bigger the better. An inductor is also a choke to reduce RF but not as effective and it does have losses on the line

A coil of wire or a coil in the shape of a cylinder is a typical shape for an electromagnet (or a solenoid). The strength of the magnetic field of an electromagnet can be increased significantly if the coil is wrapped around an iron core. This configuration may be called an inductor when used as an element of an electrical circuit.

If you put iron in the core of an inductor, it will increase the inductance of the inductor. Iron has a higher permeability compared to air or other materials typically used in inductors, allowing the magnetic field to be more concentrated and increasing the efficiency of the inductor.

A ferrite core is used in electronic components such as transformers and inductors to increase the inductance and efficiency of the component. It helps to concentrate magnetic flux and reduce losses due to eddy currents, making the component more effective at its job.
Ferrite cores are used to suppress electrical noise on conductors. A split ferrite is installed over a conductor as close to the source of noise as possible. A solid ferrite has the conductor routed through it, it may also have several turns of the conductor looped through the donut shaped ferrite. Take a look at a motherboard and you'll see ferrites in use in the power supplies.
