23-CBSA-2.75X3.25X0.25

RF Shields are utilized to protect circuit boards and components from the effects of electro-magnetic interference. They are used in a variety of industrial, automotive, medical, electrical, and consumer applications. The 23-CBSA-2.75X3.25X0.25 model is a specialized shield designed for a specific application.

The purpose of the 23-CBSA-2.75X3.25X0.25 is to attenuate or reduce radio frequency interference (RFI) from outside sources before it reaches the internal components and damage the circuit board. It is a three-layer shield with an inner core made of nickel-plated stainless steel. The outer and top layers are composed of conductive aluminum. The inner core is connected to the ground terminal via a ground bar.

The aluminum layers form an electric field that creates an electro-magnetic shield in the region between them. The varying frequencies of the incoming RF signals create currents that spread along the metallic surfaces due to the alternating electric field. The conductivity of the metal prevents the RF signal from penetrating the shield. The strength of the field depends on the thickness of the aluminum layers, the size of the shield, and the frequency of the RF signal.

The 23-CBSA-2.75X3.25X0.25 is typically used in automotive, medical, electrical, and consumer applications where sensitive components and circuit boards need protection from EMI interference. The design of the shield allows it to be used in limited space applications such as handheld devices and other consumer electronics. It is also suitable for protection in high-speed data processing systems. The shielding effectiveness exceeds 90dB at frequencies between 0.5MHz and 3GHz. This makes it an ideal choice for most RF shielding applications.

The 23-CBSA-2.75X3.25X0.25 shield is easy to install and requires minimal maintenance. It can be mounted directly onto the circuit boards, components, and devices that require protection from EMI interference. The shielding effectiveness of the shield is not affected by the surface finish, material, or shape of the device. The shield is durable and can withstand environmental conditions such as extreme temperatures, humidity, and dust.

In summary, the 23-CBSA-2.75X3.25X0.25 is a specialized RF shielding device designed to protect circuit boards and components from EM interference. It is made up of three layers: the inner core of nickel-plated steel, and the outer and top aluminum layers. It is suitable for limited space applications and is effective at frequencies between 0.5MHz and 3GHz, providing over 90dB of shielding. The shield is easy to install and requires minimal maintenance, making it an ideal choice for many RF shielding applications.
