RF Shields

Radio Frequency (RF) shielding mechanisms provide applications with a reliable and cost-effective way to protect electronic components from electromagnetic interference (EMI). The most common type of RF shield is a 20S-CBSA-1.25X4.0X0.2 shield. This type of shield offers superior protection when used in applications with relatively low levels of surrounding EM fields.

The 20S-CBSA-1.25X4.0X0.2 shield is a four-layer wrap design. It has a 0.2 mm thickness of low-carbon steel foil shields, bonded together by a multilabel adhesive. Each layer of the shield is designed to provide maximum isolation and minimum signal leakage. All four layers have an electrical conductivity of 1.26 x 10-6 S/m and a relative magnetic permeability of 1.25.

The shield is designed to operate at frequencies of up to 4 GHz. The shield is suitable for all types of EMC (electromagnetic compliance) applications where signal leakage and attenuation are critical, such as avionics, automotive, and industrial equipment. The shield is also suitable for applications involving RF components, such as wireless networks, Bluetooth, and cellular networks.

One of the key elements of a good RF shield is the ability to attenuate the intensity of an EMI field. The 20S-CBSA-1.25X4.0X0.2 shield is designed to attenuate signal peaks by up to 40 dB, providing effective EMI protection. The attenuation achieved depends on the size and frequency of the incoming signal.

Another important feature of the 20S-CBSA-1.25X4.0X0.2 RF shield is its shielding effectiveness. A good RF shield should be able to block the transmission of EM signals, thus limiting their potential to create cross-talk in other components or systems. The 20S-CBSA-1.25X4.0X0.2 shield is capable of blocking up to 95% of EMI signals, allowing for efficient data transmission over radio, cellular and Wifi networks.

The 20S-CBSA-1.25X4.0X0.2 shield is also designed to reduce the levels of electromagnetic radiation. A good RF shield should be capable of reducing the levels of electromagnetically released radiation to a safe level. The 20S-CBSA-1.25X4.0X0.2 shield is designed to reduce the levels of radiation to below 10 dB, ensuring that nearby equipment, persons, and the environment are protected from harmful EM radiation.

The 20S-CBSA-1.25X4.0X0.2 RF shield is a useful solution for many EMC applications, providing superior signal attenuation and shielding effectiveness. Its thick layers of low-carbon steel foil, bonded together with a multilabel adhesive, act as a reliable barrier for EM radiation. The shield is designed to offer maximum isolation and minimum signal leakage, allowing users to effectively protect their electronic components from EMI.
