Mag. Layers USA offers ferrite beads in 30 different frequency values. These products have a specific frequency that enables it to act as an RF choke, providing inexpensive but highly effective RF shielding, parasitic suppression and RF decoupling at specific (high) frequencies.

Although essential to shielding RF frequencies, small and inexpensive ferrite beads are often overlooked in the design of electronic components-until the last minute. But since ferrite beads are frequency-specific, there are times when manufacturers need a whole lot of them, only to find that they won't be available form their supplier for perhaps months. And the lack of availability of ferrite beads in the needed frequencies will halt production of a new or existing product for whatever period of time it takes to get them.
