Fehonda® BS-ER Absorber Pad

Fehonda® BS-ER EMI Absorber Pad: High Thermal Stability EMI Damping Solution

The BS-ER Absorber Pad is designed to enhance the reliability of electronic devices by damping electromagnetic interference (EMI) through noise absorption. This flexible material converts electromagnetic energy into thermal energy, preventing internal cavity resonance and the re-radiation of electromagnetic fields often caused by reflective shielding.

Core Technical Performance:

• Frequency and Attenuation Focus: The pad is effective across a broad frequency band from 10 MHz to 6 GHz, delivering an absorption rate between 40 dB and 180 dB within this range.

• Density: The density is specified as 3.2 ± 0.3 g/cc (ASTM D792).

Structural and Safety Features:

• Thermal Stability: It exhibits high thermal stability with a continuous use temperature range set between -40°C and 120°C.

• Hardness and Flexibility: It has a hardness of 65 ± 5 Shore A (ASTM D2240). Its flexible structure ensures a good fit on complex surfaces and allows for easy die-cutting into various shapes.

• Safety Certification: Meets UL 94 V-0 flame retardancy requirements.

• Physical Durability: Corrosion resistance and stable physical properties ensure long-term performance even in harsh environmental conditions. The available thickness range is 0.3 mm to 5.0 mm (ASTM D374).

Critical Sectoral Application Areas:

• 5G Data Infrastructure and 5GTelecom: Suppression of high-frequency signal noise.

• Automotive and Industrial Electronics: Stability across a wide temperature range.

• Wearable Electronics, Robotics, and Consumer Electronics.

• Military, Security, and Mobile Infrastructure: Electromagnetic wave protection for critical systems.
