RF and EMI shielding and absorbing materials play an important role in protecting sensitive electrical equipment from the unwanted effects of electromagnetic interference. The 5-1125-3/4-4R shielding and absorbing material is one of the best on the market today. This article examines the application field and working principle of this material.

5-1125-3/4-4R shielding and absorbing material is a low impedance, high frequency absorber with low reflection characteristics. Its frequency range is from low frequencies of 0.5 MHz up to 33 GHz. This material is ideal for radio frequency interference (RFI) and electromagnetic interference (EMI) shielding applications in aerospace and communications systems. It is also used in industrial, medical, and consumer electronics, as well as in high-end automotive applications.

The 5-1125-3/4-4R shielding and absorbing material is composed of a polyolefin foam and an electrically conductive carbon loaded coating. The foam structure contains millions of micro-voids and channels that allow the electromagnetic waves to be dissipated into the material. This process creates the shielding effect. The polyolefin foam also helps to reduce noise and enhance the absorption characteristics. Due to its conductive coating, the material offers excellent shielding and absorbing performance over a wide frequency range.

The working principle of the 5-1125-3/4-4R material is based on the concept of "resonance absorption." This means that the material acts as an absorber, absorbing the incoming electromagnetic waves and dissipating them as heat. The mode of operation of the material is composed of two components: the absorption of the radiation energy, and the reflection of the radiation energy back into space. The absorption of the energy is done by the foam material, while the reflection is facilitated by the conductive coating.

The 5-1125-3/4-4R material is designed to effectively reduce the Strength of Electric Field (SEF) in its vicinity. It does this by blocking or absorbing the RF energy that passes through it. When the material is placed near a piece of equipment, the RF energy is absorbed and the SEF is significantly reduced. This results in improved system performance, as well as reduced energy consumption.

The 5-1125-3/4-4R material can also be used to reduce the levels of noise in a given environment. It does this by absorbing and dissipating the frequencies that are present in the environment. This results in a smoother and more consistent sound quality, as well as enhanced communications systems performance.

In conclusion, the 5-1125-3/4-4R shielding and absorbing material is an ideal solution for those looking to reduce their risk of electro-magnetic interference in their environment. It is a low impedance, high frequency absorber with low reflection characteristics that can be used to effectively reduce the Strength of Electric Field and noise levels in a given environment. Its use in aerospace and communications systems, industrial, medical, and consumer electronics, as well as in high-end automotive applications is well-established.
