Our 3600 series Ferrite absorber tile is the industry standard solution and shows excellent overall performance versus cost. 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 a quite new development.

They are used when relatively high absorption is required together with a compact solution (-15 to -25 dB @ <100 MHz) - approximately 4 to 6 mm vs 2400 mm for foam absorbers. They also provide a reliable and compact solution for attenuating plane-wave reflections in shielded enclosures.

3620 Double-layer ferrite absorber tile

3620 Double-layer ferrite absorber tile is especially designed for small EMC anechoic chambers, to get excellent electromagnetic absorption performance in 30 MHz to 2 GHz.

The 3620 Double-layer ferrite absorber tile contains a 21 mm gap between two pieces of 100 x 100 x 3 mm sintered ferrite tile and has a total thickness of 27 mm. It can be glued on to a wall easily.

Due to the special double layer design, these tiles provide a wider frequency range than single-piece ferrite tiles, even in a small anechoic chamber or a dark box for mobile phone inspection.
