C-FO-LF is a thin, flexible EMI absorbing sheet with high magnetic permeability (180 ± 20), engineered to suppress electromagnetic interference in the 10MHz to 6GHz range. Its excellent flexibility and ultra-thin profile (0.03–0.5mm) allow easy application on FPC or chip surfaces, effectively reducing CPU radiation and smartphone SAR levels and making it a premier solution for EMI issues in high-end communication and mobile devices.

C-FO-LF Low-Frequency EMI Absorbing Sheet: High Permeability with Precision Noise Suppression

C-FO-LF Low-Frequency EMI Absorber: High-Permeability Noise Suppression Solution

In modern high-frequency communications and compact electronic designs, electromagnetic interference (EMI) is a key factor affecting system stability. The C-FO-LF low-frequency EMI absorbing sheet developed by Lixing Composite Materials is a high-performance absorber with high permeability (μ’ = 180) that is flexible and resistant to cracking. By filling a resin matrix with an ordered, high-loss electromagnetic absorbent, it captures electromagnetic waves and converts them into a small amount of heat, effectively eliminating noise interference inside electronic systems.

Why Choose the Lixing C-FO-LF EMI Absorber?

The C-FO-LF series combines materials science with precision processing to solve the brittleness and thickness limitations of conventional ferrite sheets:

• Ultra-thin design: A wide thickness range (0.03mm ~ 0.5mm), down to just 0.03mm, fits the extremely limited internal space of mobile devices.

• High permeability: Permeability of 180 ± 20 provides superior magnetic field guidance and absorption.

• Physical flexibility: The resin carrier gives excellent toughness, with no risk of fracture even under bending or vibration.

• Environmental compliance: The whole series meets RoHS and REACH requirements, satisfying international green-product standards.
