21M-CBSA-2.0X5.0X0.225

RF shields are an important component of modern electronic devices, used to assist in the containment and protection of sensitive receiver circuits. The 21M-CBSA-2.0X5.0X0.225 is a commonly used RF shield and is capable of working with a range of RF and microwaves frequencies. The purpose of this article is to explain the application field and working principle of this particular type of shield.

Application Field

The 21M-CBSA-2.0X5.0X0.225 shield is primarily designed for use in high-frequency shielded environments, such as in electronic components found in consumer electronics, telecommunications, automotive, avionic, and industrial systems. In these applications, the shield helps to protect the components from outside interference, such as from Radio Frequency (RF) or Electro-Magnetic Interference (EMI). The shield is also useful in controlling the movement of electrical current within the component.

Working Principle

The 21M-CBSA-2.0X5.0X0.225 shield uses a combination of physical shielding and electromagnetic shielding to protect the sensitive components. The physical shielding is made from a metal alloy, typically aluminum, which forms a barrier around the vulnerable components. This barrier helps to reduce the level of RF and EMI penetrating the component. The second element of the shield is the electromagnetic shielding, which is composed of an electromagnetic absorber, such as Ferrite. This absorber absorbs the unwanted radiation, and also helps to minimize the amount of stray RF signals that could cause interference.

The combination of physical shielding and electromagnetic shielding provided by the 21M-CBSA-2.0X5.0X0.225 shield helps to make it an effective tool for protecting components in a high-frequency environment. It is also an affordable and cost-effective solution for providing a level of protection in a wide variety of applications.
