Ferrites are electronic components used to store energy in electronic circuits. Ferrites are made of ferrite, a metallic substance, and create a magnetic field on a coil through which an electric current is passed. Ferrites are used to block the variation of electric current like inductors, but they work better at higher frequencies.
Ferrites are available in a variety of sizes and shapes and are made from a variety of materials. Ferrites, like resistors, are rated by their inductance value and measured in henry (H). The inductance value shows how the ferrite affects a current and there are various inductance values suitable for different applications.
Ferrites can be sensitive to environmental conditions and should therefore be handled with care. In particular, temperature and humidity conditions can affect the lifespan of ferrites.
Ferrites are often used in various electronic circuits such as signal processing, filtering, and power supplies. In particular, ferrites are used in filters to improve the transmission of high-frequency signals and to reduce power loss in power supplies.
Ferrites may be more expensive and more difficult to manufacture than other electronic components, but they perform better in high frequency applications than others.
