Almost has the same performance in low frequency as the pyramid absorbers (with tips); but its performance in high frequency might be slightly declined
The 3660 series PU foam based Hybrid absorbers product is similar to our standard pyramid absorbers, but having the tips of the pyramids truncated. This saves space in small chambers and provides a more rugged product, eliminating the possibility of tip breakage.
PU foam based Hybrid absorber in an appropriate combination in a EMC anechoic chamber and is an ideal absorber treatment for Immunity Test Chambers (EN 1000-4-3 and equivalent specifications).
Removing 20% from the tips of pyramid absorbers (low carbon), it is the Truncated absorbers (without tips), which almost has the same performance in low frequency as the pyramid absorbers (with tips); but its performance in high frequency might be slightly declined. The advantage of such absorbers is bringing a larger net space, eliminating the tips droop, and it has a stronger resistance capability against mechanical damage.
