Ferrite absorber tile is the industry standard solution and exhibits excellent overall performance versus cost in shielded enclosures
Our 3610 series Ferrite absorber tile is the industry standard solution and exhibits excellent overall performance and cost savings in shielded enclosures. It is an attractive alternative to traditional, large, foam-type absorber materials for new anechoic chambers or for upgrading existing rooms for radiated emission and immunity measurements.
These tiles are recent development and recommended for use when relatively high absorption is required together with a compact solution (up to -37 dB @ 800 ~ 900MHz). They also provide a reliable and compact solution for attenuating plane-wave reflections in shielded enclosures.
For the best economical choice, see our most common 3600 series VHF ferrite absorbers. These are the most frequently used choice for Anechoic chambers.
Lower electromagnetic waves absorption in the range of 30 MHz ~ 1 GHz
Wide frequency and fire resistant
An electromagnetic absorbing material
Easy and quick to assemble
No physical degradation over time
Ultra thin so it takes up little space
Our UHF Ferrite Absorber tile is made of a sintered ferrite in the shape of a square tile. The dimensions are 100 x 100 mm or 600 x 600 mm with a thickness of 4.0 mm.
The tiles can easily be screwed on to a wall individually, inserting screws through the 10mm hole, or mounted by means of adhesive. The tiles are optionally available in panels. These tiles are surface-ground on all sides to precise mechanical tolerances, minimizing gaps between adjacent tiles to ensure maximum low-frequency performance.
The tiles provide excellent electromagnetic absorption in the UHF band and works well in a Dark box for mobile phone inspection and EMC anechoic chambers. It is also suitable for high buildings to prevent TV ghost or for the absorption of RFID.
