EMI Absorbing Materials
Flexible wave-absorbing sheets that attenuate electromagnetic interference across MHz–GHz bands. They reduce coupling between noise sources and sensitive circuits, and are thin enough to fit in the most space-constrained housings.
Strengths
- Broadband attenuation from MHz through GHz — grade selected by frequency target
- Soft and conformable — follows curved or uneven mounting surfaces
- Minimal thickness profile; negligible impact on assembly envelope
- Available with no adhesive, single-sided, or double-sided PSA
- Ferrite loading level adjustable to tune target frequency band
- RoHS compliant; halogen-free formulations available
Customization
- Thickness and permeability grade per frequency target
- Adhesive configuration: none / single-sided / double-sided PSA
- Custom shapes via die-cut or laser cut
- Halogen-free compound on request

Installation Notes
- 5G base station RF and antenna modules
- Wi-Fi routers and IoT device housings
- Automotive radar and proximity sensors
- Server NIC and high-speed data buses
- Optical transceivers and SFP/QSFP cages
- Smartphones, tablets, and wearables
Installation Notes
- Place between the noise source and the sensitive victim circuit
- Where vibration is present, use adhesive-backed variant to prevent shifting
- Avoid creasing or folding — material performance degrades at sharp bends
- Measure attenuation in the final assembled board before production approval
