Ferrite Disks

 Ferrite discs are magnetic materials commonly used as cores in transformers and high-frequency inductor coils. They are made of ferrite, a ceramic material composed mainly of iron oxide and zinc oxide.

Ferrite discs have a flat, circular structure and are manufactured in a variety of sizes and shapes to suit the specific needs of each application. They are designed to be placed inside a transformer or inductor coil to increase the efficiency and current handling capacity of the coil.

Ferrite has high magnetic permeability at high frequencies, which means that it can concentrate the magnetic field in a small area and improve the efficiency of the coil. Additionally, ferrite discs have high electrical resistance and low hysteresis loss, making them ideal for use in high-frequency applications.

Another advantage of ferrite discs is their resistance to oxidation and corrosion, making them suitable for use in harsh environments. In addition, they are relatively inexpensive and easy to manufacture in large quantities.
