FS-600H FerroSorb™ EMC Absorber

FS-600H FerroSorb™ EMC Absorber

ETS-Lindgren FerroSorb™ FS-600H is the latest evolution in low profile anechoic technology. Specially designed for three and five meter EMC chamber applications, this numerically optimized hybrid combines high performance carbon-loaded foam absorber with precision-manufactured ferrite tile. The result is a space-saving profile that is less than half the depth of traditional foam-only products.

Description

The FS-600H design features an ultra broadband 30 MHz to 18 GHz* frequency range and achieves superior levels of absorption and powerhandling capability. Chambers designed with FerroSorb™ FS-600H will supersede the +/- 4 dB normalized site attenuation requirements specified in ANSI C63.4 and EN50147-2 at both five meter and three meter test distances.

Applications

FerroSorb™ FS-600H is designed for three and five meter EMC chamber applications. The product is ideal for use where three meter Class B compliance product testing, per FCC and EN 50147-2 regulations, will be performed. FS-600H can also be used for compliance testing to IEC 61000-4-3, MIL-STD 461E and EN 55022 and other common EMC test applications.

Description

FerroSorb™ FS-600H is manufactured from high quality, low density polyurethane foam and undergoes 15 quality assurance checks during production. The manufacturing process begins with the foam being submerged and impregnated with a proprietary, conductive carbon formula. It is then inspected and force-dried. After drying, the foam is submerged and impregnated in a water-soluble salt solution and is again inspected and force-dried. This double-immersion process ensures FerroSorb's high levels of fire retardancy and resistance to moisture. The foam is then cut into a precise hollow wedge configuration and an attractive, fire-retardant coating is applied for an added level of protection. The polyurethane dielectric is mounted on a specially formulated, precision-machined ferrite tile.

Features

FerroSorb™ FS-600H has a unique composite construction that combines the best of ferrite tile technology with high performance anechoic absorber to achieve an ultra broadband operating frequency of 30 MHz to 40 GHz.

Absorption/reflectivity performance of FS-600H’s 600 mm (23.62 in) size is superior to dielectric material measuring more than twice its depth.

FS-600H has excellent power handling capability for today's immunity standards testing, and can safely handle continuous exposure to fields up to 200 V/m.

The product's reduced size, as compared to traditional foam-only absorber, means that overall room size can be reduced, resulting in significant total project cost savings.

FerroSorb™ FS-600H is fire retardant and meets the standards of NRL 8093 Tests 1, 2 & 3, TI #2693066, MIT MS-8-21, UL 94, and DIN 4102-B2: Tests for Flammability.

Non-destructive reflectivity measurements are performed on every piece of FerroSorb. In the critical low frequency range of 30 MHz to 500 MHz, a vertical coaxial waveguide is utilized as specified in IEEE 1128. Testing at higher frequencies is performed using the NRL Arch technique. These precise tests assure quality of the complete absorber, resulting in optimized chamber performance.
