Noise Suppression Sheets

Function: Absorb or block electromagnetic interference (EMI) and high-frequency noise in electronic devices.

Typical Applications:

• Mobile phones, tablets, laptops
• Wearable devices
• Automotive electronics
• High-speed digital circuits

Key Features:

• High magnetic permeability (ferrite or conductive composites)
• Thin, flexible form factor
• Adhesive backing for easy mounting
• Effective across a broad frequency range (MHz to GHz)

Common Materials:

• Ferrite-based sheets
• Conductive rubber or foam
• Carbon-loaded polymer films

Selection Tips:

1. Match suppression sheet frequency response to noise source.
2. Ensure proper grounding if using conductive types.
3. Place close to noise sources (e.g., processors, RF modules).
4. Consider thermal and mechanical constraints in design.
