RF Shields

Radio Frequency (RF) shields are devices used to protect electronic components from the interference of radio frequency signals. This is done by shielding or blocking the high frequency signals generated by the components, thus preventing them from interfering with each other and other nearby electronics. The most common type of RF shield is the 3690103021.

3690103021 Application Field

The 3690103021 is a widely used RF shield found in many electronics. It is mainly used in the field of high-frequency circuit applications, such as mobile phones, military radios, and other communication equipment. It is also used in aerospace, automobiles, medical, and other fields for the protection of electronic components.

3690103021 Working Principle

The 3690103021 is a high-frequency shield mainly composed of three materials, brass, copper and aluminum. The shield itself is made up of three layers, a brass layer, a copper layer and an aluminum layer, which are arranged in this order. The brass layer is the one that is closest to the components and is the layer that absorbs most of the high frequency radiation. The copper layer adds additional shielding, and the aluminum layer forms a radiator, which is the farthest from the components and is responsible for releasing the high frequency energy safely into the atmosphere. When the radiation is absorbed by this three-layer shield, it is converted into heat, which is then released into the atmosphere.

In addition to the brass, copper, and aluminum layers, the 3690103021 also has an inner core, which is a foam-like material. This acts as an insulator and helps to reduce the reflection of high frequency radiation from the shield. It also serves to reduce the overall weight and maximize the shielding efficiency.

Another important part of the 3690103021 is its EMI band suppression technology. This technology adds another layer of shielding by helping to reduce the amount of interference that is produced by the components in the device. It does this by creating a narrow frequency “window” that allows only certain frequencies to pass through, thus decreasing the overall frequency emissions from the system.

Conclusion

The 3690103021 is a widely used high-frequency RF shield that is used in many electronics. It is composed of three layers, brass, copper, and aluminum, and an insulating foam core. It is commonly used in electronic components, especially in high-frequency circuit applications. It also has EMI band suppression technology, which helps reduce interference from the component. This RF shield is essential for protecting components from interference caused by high-frequency signals and provides maximum protection for electronic components.
