Fehonda® BS-3G Absorber Pad

Fehonda® BS-3G Absorber Pad: Magnetic Noise Damping Solution for the 3 GHz Frequency Range

The BS-3G Absorber Pad is engineered to prevent internal cavity resonance and the re-radiation of electromagnetic fields often caused by conventional reflective shielding. This magnetically loaded pad actively suppresses noise from high-speed digital circuits and RF modules by converting the energy into imperceptible heat.

Core Technical Performance:

• Frequency and Attenuation Focus: The product is optimized around a 3 GHz main frequency, delivering 15 dB of absorption at this point. This performance specifically targets critical noise sources in 5G telecommunications and high-speed digital signal paths.

• Density and Magnetic Composition: The density is specified as 3.5 ± 0.3 g/cc (ASTM D792).

Structural and Safety Features:

• Thermal Stability: It exhibits high thermal stability with a wide continuous use temperature range set between -40°C and 160°C.

• Hardness and Flexibility: It has a hardness of 60 ± 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. This is a fundamental prerequisite for high-security sectors like defense and telecommunications.

• 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.
