Description

ETS-Lindgren's FerroSorb™ FS-1001 is a numerically optimized hybrid that combines high performance carbon-loaded foam absorber with precision-manufactured ferrite tile designed specifically for use in 10 meter EMC chambers. This ultra broadband composite achieves superior levels of absorption and power-handling capability in a space-saving profile.

The FS-1001 design features ultra broadband performance from 30 MHz to 18 GHz*, achieving superior levels of absorption and exhibiting excellent power-handling capability. Chambers designed with FerroSorb™ FS-1001 will perform better than the +/-4 dB normalized site attenuation requirements specified in ANSI C63.4 and EN50147-2.

Applications

FS-1001 was developed to provide ultra broadband performance for 10 m EMC chamber applications. It is designed to meet Class A and Class B EUT testing requirements per FCC / ANSI C63.4 and EN 50147-2 regulations. FS-1001’s high absorption performance and power handling capability allows it to be used for IEC 61000-4-3 and MIL-STD 461E testing requirements. FS-1001 can be used for new construction as well as upgrading the performance of existing rooms.

Description

FerroSorb™ FS-1001 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 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 with a tuned dielectric layer. To enhance high frequency performance, additional 15 cm (6 in) pyramidal absorbers are positioned at the base of the larger absorber.

Features

FerroSorb™ FS-1001 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 18 GHz.*

Absorption/reflectivity performance of FS-1001’s 1000 mm (39.4 in) size is superior to dielectric material measuring up to twice its depth.

FS-1001 has excellent power handling capability for today's immunity standards testing, and can safely handle continuous exposure to fields up to 200 V/m.

FerroSorb™ FS-1001 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 measure-ments 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.
