This Ferrite based absorber is both light and flexible and absorbs electronic waves, reduces noise and also absorbs shocks. Depending on the absorber thickness, it covers a range of 30 MHz to 5GHz.
The thicker type is more effective for lower frequencies. The absorber can be delivered with a conductive or a non-conductive adhesive.
EMI absorbing materials are commonly found amongst high-tech products such as LCD electronic devices, laptop and desktop computers. Electromagnetic wave absorbing materials are composed of dielectric materials mixed with ferrite, a magnetic material, with varying shapes and sizes. They are intended to absorb electromagnetic energy at normal and large incident angles over a wide range of frequencies.
Standard size 210x297 mm, thickness 1,0-3,0 mm.

Hybrid absorber
These absorbers are the most popular solution for 3m, 5m and 10m EMC chambers in the market. They are composed of pyramidal, full tip SAM or truncated SMT pulsing the matching layer to separate the pyramidal part from the ferrite part. Through optimization, this product has a superb performance across 30MHz to 18GHz. The ferrite performes from 30MHz to 1GHz and the foam performes above 1GHz.
Ferrite tiles
The 100mm tiles can be installed individually using screws or adhesive and are optionally available in panel format. Tiles are surface ground on all sides to precise mechanical tolerances, minimizing gaps between adjacent tiles to ensure maximum low-frequency performance.
Tile Absorber
Ferrite Tile is the industry standard size and exhibits excellent overall performance versus cost.
