vhf ferrite absorber tiles icon 1


Our 3600 series Ferrite absorber tile is the standard solution for industrial applications. It is an attractive solution for new anechoic chambers or for upgrading existing rooms for radiated-emission and immunity tests.

These tiles are used when relatively high absorption and a compact solution are required (-15 to -25 dB <100MHz). It is an excellent, reliable, and compact solution for attenuating reflections in shielded enclosures.

3600 VHF ferrite absorber tile

The VHF ferrite absorber tile is made of sintered ferrite and shaped like a square tile. The dimensions are 100 x 100mm with a thickness of 6.7mm.

The tiles are subject to precise mechanical tolerances on all sides, minimizing gaps between adjacent tiles to ensure maximum performance.

The tiles provide excellent electromagnetic absorption
performance in the VHF band for EMC anechoic chambers.

Please note: These ferrite tiles are very thin, which can save more space for chamber installation. The tiles are non-flammable and they can be fully suitable for high-power test chambers. Ferrite tiles can be screwed directly on to the shielded housing; installation is very easy. Even after many years the effect of the ferrite tiles still will not be degraded.

Supplied as 600 x 600mm panels (optionally available)

Both the 3600 VHF ferrite absorber tile and the 3610 UHF ferrite absorber tile are optionally available in the panel format of 36 Ferrite absorber tiles.
