What is a Ferrite Bead?

A ferrite bead, or ferrite choke, is a simple hollow cylinder or bead that is made of ferrite material and that is used in order to suppress or filter the amount of high frequency electromagnetic interference (EMI) noise found in electronic circuits. Ferrite is a black semi-magnetic substance that is shaped like a cylinder and that consists of iron oxide along with a mixture of other metals. Ferrites are encased in rubber or plastic material to protect and keep the ferrite bead in place.

Types of Ferrite Beads

There are several different kinds of ferrite beads. At Future Electronics we stock many of the most common types categorized by maximum DC resistance, case size / dimension, rated current, impedance, operating temperature range and packaging type. The parametric filters on our website can help refine your search results depending on the required specifications.

The most common sizes for impedance are 120 Ω, 220 Ω, 600 Ω and 1kΩ. We also carry ferrite beads with impedance up to 2.7 kΩ. The rated current can be between 0.2 mA and 4000 A, with most ferrite beads having a rated current of 200 mA or 500 mA.

Ferrite Beads from Future Electronics

Future Electronics has a complete selection of ferrite beads from several manufacturers that can be used as a ferrite bead for a cell phone, ferrite bead for USB or ferrite bead for a headset, among other uses. Simply choose from the ferrite bead technical attributes below and your search results will quickly be narrowed in order to match your specific ferrite bead application needs.

If you have a preferred brand, we deal with Murata, NIC Components, Samsung, TDK or Yageo America Corporation, among other manufacturers. You can easily refine your ferrite bead product search results by clicking your preferred ferrite bead brand below from our list of manufacturers.

Applications for Ferrite Beads:

Ferrite beads can be used for the removal of power line noises in cellular phones, PCs, TV tuners, audio players, DVDs, game machines, digital photo frames and several other electronic circuits.

Choosing the Right Ferrite Bead:

When you are looking for the right ferrite beads, you can filter the results by various attributes with the FutureElectronics.com parametric search: by Maximum DC Resistance (1 mΩ, 50 mΩ, 100 mΩ, …), Rated Current (0.2 mA, 200 mA, 500 mA,…) and Impedance (from 1 Ω to 2.7 kΩ). You will be able to find the right ferrite bead for USB, ferrite bead for a cell phone or ferrite bead for a headset.

Ferrite Beads in Production Ready Packaging or R&D Quantities

If the quantity of ferrite beads required is less than a full reel, we offer to customers many of our ferrite bead products in tube, tray or individual quantities that will help you avoid unneeded surplus.

In addition, Future Electronics offers its clients a unique bonded inventory program designed to eliminate potential problems that could arise from an unpredictable supply of products containing raw metals and products with long or erratic lead times. Talk with your nearest Future Electronics branch so you can find out more on how you can avoid possible shortages.
