21L-CBSA-0.75X1.0X0.225

RF shields are used to shield low frequency (LF) and high frequency (HF) radio waves from entering and leaving an electronic device. They are effective in controlling RF emission from a device and ensuring that the signals from and inside the device are not disturbed by external electromagnetic interference. RF shields are essential components in any device designed to meet electromagnetic compatibility requirements and reduce the amount of external electromagnetic interference it is exposed to.

The 21L-CBSA-0.75X1.0X0.225 is a type of RF shield designed for general purpose applications. It is made from steel and is designed to provide shielding for LF and HF radio waves, as well as shielding against static fields. This type of RF shield has a shielding effectiveness (SE) of approximately 90-100 dB. The 21L-CBSA-0.75X1.0X0.225 is commonly used in products such as cell phones, laptops, tablets, and other electronic devices.

Application Field and Working Principle

The 21L-CBSA-0.75X1.0X0.225 shield is used for RF shielding in a variety of applications. One of the most common applications is in cell phones. This type of shield is also used in laptop computers, tablets, and other electronic devices. The application of this type of RF shield is to prevent external radio waves from entering the device and interfering with the functions of the device. Similarly, the shield is used to prevent radiation generated by the device from escaping the device and interfering with other devices in the vicinity.

RF shields work by creating an electrostatic barrier between the device and external radio waves. The shield helps to block radiation emitted by the device as well as radiation from other sources. The shield is also known to attenuate incoming signals, thus limiting interference.

In addition to RF shielding, the 21L-CBSA-0.75X1.0X0.225 shield is also designed to provide effective static field shielding. This type of shield is designed to reduce the amount of static electric fields that can enter the device. The shielding effectiveness of this type of shield can be up to 1000 V/m. This type of shielding is essential in protecting devices from damage caused by static electric fields.

In conclusion, the 21L-CBSA-0.75X1.0X0.225 shield is an essential component for any device designed to meet electromagnetic compatibility requirements. This type of shield is effective in shielding both radio frequency and static electric fields from entering and leaving the device. Furthermore, this type of shield is commonly used in a variety of applications from cell phones to tablet computers.
