RF Shields, also known as radio frequency shields or radiation shields, are devices that can be used to protect sensitive circuits and systems from interference due to radio frequency (RF) signals.

20S-CBSA-1.5X4.0X0.2 is a type of RF shield that is mainly used to protect sensitive circuits and systems from electromagnetic radiation, RF interference, and other harmful interferences. It offers excellent shielding effectiveness and a high level of electrical insulation over a wide temperature range. The construction of the shield consists of a metal-foil type of outer shell, and an inner dielectric material formed into two halves. The two halves are then held together with screws, rivets, and gaskets. The shielding effectiveness of this type of RF shield is measured as the ratio in dB of power dissipated outside the shield to the power supplied to the shield.

The application fields of 20S-CBSA-1.5X4.0X0.2 RF shields include: consumer electronics, automotive industry, communication systems, medical electronics, and aerospace. It can be used to protect circuits, systems, and equipment from interference, as well as to block RF signals from entering or leaving a device. It can be used to prevent signals from being transmitted between two locations, as well as to protect objects from external RF signals.

The working principle of 20S-CBSA-1.5X4.0X0.2 RF shields is based on Faraday\'s principle, which states that an electrical current is generated in a loop of wire when it is subjected to a changing magnetic field. The generated electrical current flowing through the metallic layer of the RF shield creates an opposing current that cancels out the incident electromagnetic field. This is because of the conservation of energy: the energy from the incident field is consumed when the opposing current is generated. As a result, the energy of the incident field is reflected back, and the RF shield provides a high degree of secrecy between the device and its user.

20S-CBSA-1.5X4.0X0.2 RF shields are highly effective at providing a high level of signal attenuation and protection from harmful interference. It is suitable for use in a wide range of applications, including consumer electronics, automotive industry, communication systems, medical electronics, and aerospace. Its excellent shielding effectiveness makes it ideal for protecting sensitive circuits and systems from interference due to RF signals, as well as blocking external RF signals from entering or leaving the device.
