Ferrites & Ferrite Assortments

We offer various types of ferrite as described below; we also stock a wide range of ferrite assortment and design kits.

Ferrite is a ceramic-like material with magnetic properties that are useful in many types of electronic devices. Ferrites are hard, brittle, iron-containing, and generally grey or black and are polycrystalline—i.e., made up of a large number of small crystals. They are composed of iron oxide and one or more other metals in chemical combination. They offer high magnetic permeability and high electrical resistance.

Ferrites are commonly used in the electronic industry. They are found in transformers, inductors, personal computers, televisions, power supplies, electromagnets, and more. Their high electrical resistance leads to low eddy current losses.

High permeability to magnetic fields is particularly desirable in devices such as antennas. Also, by using ferrites in electrical products, manufacturers improve their ability to prevent high-frequency electrical noise. Ferrites act as EMI/RFI filters to suppress noise (Radio Frequency Interference) from entering or exiting the product. Thus, it eventually helps in improving the performance of the product and enhancing the customer experience.

A ferrite cylindrical core is the most commonly used ferrite core for cable noise or EMI suppression. A cylindrical ferrite core can be easily slipped around a cable for power decoupling and filtering. With the material and shape selection, the characteristics of a ferrite core can be completely altered.

A ferrite bead is made with ferrite material in a hollow cylinder shape to provide a simple, economical technique to attenuate or suppress high-frequency noise within electronic circuits. Alternate names are ferrite block, ferrite ring, ferrite choke, or EMI filter.

Ferrite material is used in tiles, plates, or pads in wireless power charging systems to increase system efficiency, by shielding and reflecting the magnetic field within the inductive transfer area.

A flat cable core ferrite snaps on to a cable such as a ribbon cable, or internal and external computer data and power cables, to provide electromagnetic compatibility.

A split core ferrite or sleeve ferrite clamp installs onto wired cables, and cables with connectors.
