This ultra broadband composite achieves superior levels of absorption and power-handling capability in a space-saving profile which is significantly less than the depth of traditional foam-only products.
FS-1500H is ETS-Lindgren's top-of-the-line FerroSorb product. It is specifically designed to be a cost-effective solution for EMC chamber applications that call for very high performance requirements.
Chambers designed with FerroSorb FS-1500H will exceed the +/- 4 dB normalized site attenuation requirements specified in ANSI C63.4 and CISPR 16-1-14. With an optimized chamber design, site attenuation performance of +/- 3 dB deviation from theoretical normalized site attenuation is achievable. This results in improved measurement accuracy which can translate into significant savings by reducing a product's EMI suppression costs. Other applications include IEC 61000-4-3 and MIL-STD 461E immunity testing.
ETS-Lindgren absorbers use a new fire-retardant chemical formula that is non-hygroscopic. As a result, the absorber is not affected by moisture ETS-Lindgren's FS-1500H Anechoic Absorber FS-1500H TM and will maintain its mechanical and RF performance over the life of the product.
FerroSorb FS-1500H 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-1500H is superior to dielectric material measuring up to twice its depth.
FS-1500H 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 reduced size of the product, as compared to traditional foam-only absorber, means that overall room size can be reduced as well, resulting in significant project cost savings.
FerroSorb FS-1500H 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.
Before absorbers are placed in service, they are serialized and their reflectivity performance is measured using non-destructive testing. 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.
