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.
i think Transformer operates AC and ferrite core operates in DC
what is iron core inductors
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. .
32 turns of #22AWG copper wire on a 10 mm diameter toroidal core
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

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.
It's called a "ferrite core" or "ferrite choke." It is used to filter out electrical noise that might interfere with the USB signal.
Could be an inductor / coil, without metal core.
