Absorbers, Ferrites, Magnetics & Shielding
Manufacturers & Services

These companies manufacture a variety of magnetics, absorbers, and shielding for use in RF applications. Applications range from RFI/EMI enclosures to screen rooms, custom shielding for PCBs, and machined chassis, noise filters, or ferrites for keeping RF energy on the right side of a conductor can be found here.

Achieving a successful RF design is often dependent upon proper implementation of shielding. The higher the frequency, the higher the power levels, or the more crowded the frequency band, the more difficult it is to design shielding that will provide the necessary level of isolation. Fortunately, there is a lot of design information available in the form of white papers, datasheets, and online write-ups.

For most applications, it is possible to obtain success using off-the-shelf components and well-tried methods. Sometimes, though, it is necessary to secure the assistance of engineers whose experience lies in the realm of shielding.

Please consider contacting RF Cafe advertisers first when seeking such services.

Absorber, Magnetics & Shielding Design Data

My policy is to only list companies that actually manufacture product or offer services related to the page title subject. Product distributors and sales representatives are not listed (they have their own page). This helps guarantee that each listing offers a unique product or service. NOTICE: I am no longer adding hyperlinks due to so many companies asking to be removed because of some issue with Google Statistics. Your best bet is to use a search engine to find company websites directly. If you are interested in advertising, please visit my Advertising information page.
