RF Shields are electrical shields used to reduce the radiation generated by an electronic device or circuit and protect it from interfering with the surrounding environment. The most common type of shield is the 21-CBSA-1.0X4.0X0.225, which is designed to provide protection from both radiated and incident electromagnetic fields.

This type of shield is commonly used in a wide variety of applications including industrial, military and aerospace equipment. These shields can be used to protect against the emission of RF energy, protect against the emission of electromagnetic fields, reduce the interference generated by other devices and protect sensitive electronic components from damage.

The 21-CBSA-1.0X4.0X0.225 is a single-layer shield made from aluminum or steel. It is constructed with an inner core formed by two ferrite ring materials which are bonded together with a conductive adhesive. This layer provides a good electrical connection between the two materials, allowing it to effectively absorb and dissipate any RF energy which it is exposed to.

The outer layer of the shield is made from a conductive material which provides a physical barrier to block or attenuate the radiation which is produced by the inner core. This layer is also designed to provide a low level of capacitive coupling which reduces the amount of interference that is transmitted between the two materials. This layer also helps to reduce the reflectance of the shield and helps to protect sensitive components from harm.

In order to maximize the effectiveness of the shield, the two layers must be securely connected to each other. This is done by using one or more of the following methods: solder, brazing, spot welding, fastening or tabbing. The shield should also be grounded in order to ensure that any induced electrical currents are dissipated.

The 21-CBSA-1.0X4.0X0.225 is a popular choice for applications where the emission or incident of RF electromagnetic fields is a concern. It is designed to provide a reliable and effective shield against harmful radiation and protect sensitive equipment from interference. This type of shield is typically used in industrial, military and aerospace applications for its effective RF shielding capability.
