- Power Handling Capacity: 0.5 – 1.5 kW/m²
- Environmental: RoHS compliant, low dust emission
Product Description
EMC absorber is a high-performance RF absorbing material specifically designed for anechoic chambers, EMC test sites, and shielding rooms. Its truncated pyramidal shape ensures broad frequency absorption, minimal reflectivity, and stable performance over a wide bandwidth.
Made from carbon-loaded polyurethane foam, this absorber is lightweight, flame-retardant, and easy to install. The truncated design reduces height requirements while maintaining excellent attenuation properties, making it ideal for compact chambers and hybrid test environments.
Typical Applications
- Semi-anechoic or fully anechoic chambers
- EMC/EMI compliance testing rooms
- Military and aerospace RF test labs
- Automotive radar and sensor testing environments
- Wireless communication testing (5G, IoT)
- Shielded enclosures and quiet zones for antenna testing
Product Features
- Broadband absorption from 30 MHz to 18 GHz (or as customized)
- Truncated pyramid shape for space-saving installation
- Excellent reflectivity performance and low VSWR
- Meet IEC 61000-4-3, MIL STD 462D, SAE performance requirements.
- Flame retardant (UL 94 HBF / NRL 8093 Test 1-3 compliant)
- Lightweight and easy to cut or shape on-site
- Optional surface coatings for humidity or abrasion resistance
