RF Shields, such as 21-CBSF-2.0X3.0X0.4, are components or enclosures specially configured to protect an electronic device from electromagnetic interference (EMI). EMI is usually generated as a result of radio-frequency (RF) fields, which can cause a wide range of damage to a circuit’s electronics depending on the signal strength and frequency. In order to counteract this, RF shields are specifically designed to contain electronic devices and protect them from EMI, while still allowing normal functionality.

The name 21-CBSF-2.0X3.0X0.4 comes from the fact that it is a 2.0 x 3.0 x 0.4 inch shielding frame with a special CCB soldering shield fitted inside. This shield is sealed on the top and bottom, with a small CCB soldering shield that fits in the middle and ensures that air does not escape during operation. Because of these dimensions, 21-CBSF-2.0X3.0X0.4 is ideal for mounting RF components and it is often used in high-frequency circuit designs.

21-CBSF-2.0X3.0X0.4 can be used in a variety of applications, such as wireless charging receivers and modules, DIP switches, LED drivers, and even mobile phones. It is also perfect for use in medical devices, where it provides complete protection from external RF interference.

The working principle of the 21-CBSF-2.0X3.0X0.4 is simple. The CCB soldering shield prevents EMI from entering the device through air gaps, while still allowing the normal functionality of the device. The shield also contains a conductive material that reflects the RF signals and increases signal strength. This ensures that the EMI is kept away from the electronic components inside the device, protecting them from damage.

Additionally, the 21-CBSF-2.0X3.0X0.4 provides excellent electrical insulation and low RF leakage. This is important for keeping the device’s performance robust in environments where high levels of electricity are present. In addition, the conductive material inside the shield helps to reduce external noise and increases the signal-to-noise ratio of the device.

In conclusion, the 21-CBSF-2.0X3.0X0.4 is an RF shielding frame that is designed to protect electronic devices from EMI while still allowing them to function normally. It is ideal for use in applications that require a combination of protection and high-performance functionality, such as medical devices and wireless charging receivers and modules. 21-CBSF-2.0X3.0X0.4 works by preventing EMI from entering the device through air gaps, while also reflecting the RF signals and increasing signal strength. It also provides excellent electrical insulation and low RF leakage, making it the perfect solution for a variety of applications.
