RF Shields are used to protect sensitive electronic components from Radio frequency (RF) interference. A RF Shield, such as the 40-CBSA-2.75X3.25X0.4, is a metallic box that acts as a Faraday cage, blocking signals from entering or leaving the box.

The 40-CBSA-2.75X3.25X0.4 offers a shielding effectiveness of 95 dB in the frequency range from 8 KHz to 1 GHz. The opening size of the shield is 3.25” x 2.75” and the thickness of the walls is 0.4”. The 40-CBSA-2.75X3.25X0.4 is made of copper- plated steel, which offers superior RF shielding capabilities. The box is provided with an RF sealed closure flap that is also made of copper-plated steel.

The 40-CBSA-2.75X3.25X0.4 can be used in a variety of applications such as medical equipment, scientific instrumentation, and communications systems. The shield is also effective in protecting against high power radio sources, such as radio transmitters and microwave ovens.

The working principle of a RF Shield lies in its ability to prevent the penetration of electromagnetic waves from escaping or entering the box. The metal walls of the shield act as a Faraday cage, which creates a low-impedance path for the waves, thus preventing them from penetrating the box. As a result, no signal can escape or enter the box, providing the required level of electromagnetic protection.

The 40-CBSA-2.75X3.25X0.4 is designed to provide optimal shielding performance in a wide range of applications. This RF shield can help protect sensitive electronics from damage due to RF interference, and can be used in multiple applications, including medical, scientific, and communication equipment.
