Thin, flexible, resonant-type electromagnetic wave absorber
The "SF" electromagnetic wave absorber is a thin, flexible, narrowband, magnetic-filled, resonant-type absorption sheet for free space. It has excellent power handling characteristics, low outgassing in space environments, a frequency range of 1-18GHz, and a reflection coefficient of -20dB (at normal incidence angle and design frequency; it decreases slightly below 2.5GHz). It is ideal for reducing surface current attenuation on metal surfaces, suppressing unwanted reflections within microwave modules, and mitigating cavity resonance. 【Typical Characteristics】 ○ Color: Gray ○ Operating Temperature (°C): -54 to 163 ○ Power Handling: 0.2 W/cm² ○ Thermal Conductivity: 0.6 to 1.2 W/m.K ○ Hardness (varies with thickness): Typical value 73 Shore A For more details, please contact us or download the catalog.
