Product Description
5G EMI Absorber
Absorber of absorbing type is made by adding soft magnetic alloy flake powder into polyurethane solution, coating and pressing. The soft magnetic alloy flake powder has good electromagnetic properties, and through horizontal arrangement, higher magnetic permeability characteristics can be obtained. The flake powder can form a better eddy current circuit and magnetic field orientation, and has a greater advantage in attracting and consuming electromagnetic waves.

Successful Cases
S-Company Project - Signal Interference
USB3.0 port is connected to the motherboard and USB small board through the flexible cable. Below is the SSD. The actual work will bring the noise of SSD and USB3.0 and affect the Wi-Fi signal. Through communication with R&D, the actual noise is 2.5. Around GHz, it affects the Wi-Fi 2.4G (2.4~2.4835G) signal. At present, a wave of absorbing material is attached to the soft wire corresponding to the NB D component, and this noise is absorbed to solve the problem.
