Absorber Tapes
Ultra-Thin, Flexible, High-Loss
Guanxu® GXF-series absorber tapes are flexible magnetic composite materials made by embedding novel micron-scale metallic magnetic particles into an organic polymer matrix. Designed for electromagnetic interference (EMI) absorption and suppression in the frequency range up to 6 GHz, these tapes are widely used in EMC (Electromagnetic Compatibility), EMI (Electromagnetic Interference), and ESD (Electrostatic Discharge) applications.
Key Features

Operating Frequency: 10 MHz – 6 GHz

High permeability, non-conductive

Flame retardant with excellent thermal stability

Highly flexible, ultra-thin, and easy to die-cut

Multiple thickness options, supplied with release liner

Halogen-free and compliant with RoHS standards

Market Applications
Commercial Communications: Improving PCB bit error rate (BER) in base stations, optical modules, routers, and other high-speed communication equipment
Consumer Electronics: Smartphones, tablets, laptops, and other portable devices
Automotive Electronics: Modules such as LCD displays, flexible printed circuits (FPCs), GPS units, etc.
NFC Applications: RFID, NFC, and wireless power charging (WPC) systems
Other Applications: High-speed data transmission cables, medical devices, etc.
Key Applications
Electromagnetic Field Isolation:
By leveraging the high permeability and permittivity of absorber materials—which draw electromagnetic energy toward and into the material—absorbers significantly enhance electromagnetic isolation for sensitive components.
Energy Absorption:
Utilizing the high Power Loss characteristic of absorber tapes, incident electromagnetic energy is effectively absorbed and dissipated within the material.
Suppression of Surface Traveling Waves:
Absorber materials efficiently attenuate creeping waves propagating along transmission lines (or equivalent structures) and conductive surfaces.
