RFI and EMI - Shielding and Absorbing Materials are essential components in a wide range of industrial, military, commercial transportation, and consumer electronic applications. These types of materials provide a shield from both the radiated and conducted RF and EM emissions, thus protecting sensitive parts of the system from damage or interference. This article focuses on the FFAM252*2T1 application field and working principle.

The FFAM252*2T1 is a two-layer aluminum foil and copper-clad laminate material with dielectric strength of 1.2kV/mm. It offers a wide range of shielding performance for commercial and professional applications, particularly when shielding cables and enclosures, which require high flexibility and electrical insulation. It consists of two different layers of material, one of which is an outward facing layer of aluminum foil adhered to the inner copper-clad laminate.

The aluminium foil provides 80-95dB of shielding effectiveness across a frequency range of 10MHz to 18GHz, while the copper-clad material provides 60-80dB across a lower frequency range of 300kHz to 10MHz. The combination of these two layers provides a top-class shielding performance for low-frequency and RF emissions.

In terms of its working principle, the composite layers of the FFAM252*2T1 work together to dissipate noise and RF radiation. The aluminium foil provides an effective all-around shield against outside interference, while the copper-clad laminate helps absorb the energy from every angle and stores it within the composite material. This energy is then converted into low-level thermal radiation which dissipates away from the source.

The conductivity of the copper-clad material further enhances the shielding performance of the FFAM252*2T1, as it reduces the electrical resistance of the composite material, making it less susceptible to RF and EM interference. This reduces the amount of noise which can enter the system, and increases the overall performance of the system.

Aside from its shielding performance, the FFAM252*2T1 is also robust and provides excellent mechanical strength. This makes it ideal for applications in harsh and demanding environments, including aircraft, medical equipment, and submarines. It can also withstand temperatures of up to 260°C, making it suitable for extreme temperature applications.

In conclusion, the FFAM252*2T1 application field and working principle are central to its success in a wide range of commercial and professional applications, where it provides a high level of RF and EM shielding performance and excellent mechanical strength and temperature resistance.
