EMI ESSENTIALS
RFLS 5000 SINGLE LAYER
"LOSSY" FOAM ABSORBERS
RFLS 5000 is a series of single layer "lossy" sheets
produced by dipping lightweight open-celled urethane
foam into a resistive solution. The end product is a
uniform, lightweight, loaded sheet material with a
specied insertion loss at a given frequency. RFLS
offers the lowest cost in microwave absorber products.
Thickness of the sheets range from 0.125" to 1.5"
(3,2 mm to 38,1 mm) and are generally 24" x 24"
(609,6 mm x 609,6 mm). Custom sizes and components
can be fabricated. The insertion loss of the product is
measured in an insertion tunnel over the 2 to 18 GHz
frequency range. Specications are generally given
at 3 or 10 GHz. The material can be die-cut into
components and supplied with a pressure-sensitive
adhesive for ease of application.
APPLICATIONS
RFLS sheets are used to lower noise or cavity Q's in
microwave components such as ampliers, oscillators,
computer housings and wireless equipment.
NOTES
The physical properties and electrical performance property above are typical for the material, but not intended for use in
specications or for the acceptance inspection criteria because of variations in testing methods, conditions and congurations.
