Near Field Noise Countermeasures | Functional Materials（jump）
Maxell provides thin and flexible electromagnetic wave absorbers that are compatible with the millimeter-wave band for ADAS radar and 5G communication. And also, it supports the near field use, such as ICs, circuit boards, and connectors that are noise sources.
【TC Series】Supports the frequency band from 100MHz to 10GHz (incl. Sub-6: High frequency).
Thin and flexible film by transparent conductive polymer coating.
Easy to wrap and paste, ideal for noise suppression of circuit boards, cables, etc.
【FI Series】Supports ADAS radar band (77GHz).
Flexible rubber sheet material that can be directly attached.
Ideal for noise suppression of millimeter-wave radar and in-vehicle related parts.
【FB Series】Supports 5G communication band (28GHz).
Flexible rubber sheet material that can be directly attached.
Ideal for noise suppression of circuit boards and connectors.
