Fehonda® 1.5W 5GHz Thermally Conductive Wave Absorber

1. Function and Purpose Fehonda® 1.5W 5GHz Thermally Conductive Wave Absorber is designed to absorb unwanted electromagnetic waves, especially those arising in high-frequency applications around 5 GHz. The material dampens the energy that circulates and reflects within the module, causing interference. This ensures cleaner signals and enhanced system stability in sensitive RF stages, communication units, and high-speed electronics.

2. Thermal Management Support The product is utilized not only for suppressing electromagnetic interference but also for thermal control. The 1.5 W/m·K thermal conductivity value assists in dissipating heat generated on the component's surface. This allows both signal stability and thermal control to be managed with the same material in critical modules. This approach reduces the need for additional components in high-density RF enclosures and high-density board designs.

3. Durability and Safety Profile The material is formulated to maintain its physical integrity across a wide operating temperature range of -40°C to 180°C under continuous use. Its flexible structure allows it to conform to surfaces, fill gaps, and be cut for specific application areas (thickness options from 0.5 mm to 3.0 mm are available). The product meets the UL94 V-0 flame retardancy standard and is RoHS compliant, providing advantages in both safety and regulatory compliance.

4. Typical Applications

• 5G and other high-frequency RF modules

• Communication and high-speed data transmission equipment

• Densely integrated industrial and defense electronics

• Drone, radar, and similar critical signal processing units

• The immediate vicinity of components that generate heat and simultaneously cause interference

• The objective in these environments is clear: reduce interference, protect the signal, and keep the temperature at a manageable level.
