RF Shields are a type of electromagnetic shielding which block radio frequency electromagnetic fields from penetrating a protected area in order to reduce undesired interference in a circuit. These shields are particularly necessary in electronic systems where many different radio waves are present, such as in a cellular or wireless system. The 20-CBSA-0.75X4.0X0.2 shield is a wide-range RF shield designed for use in a range of electronic applications.

The 20-CBSA-0.75X4.0X0.2 shield is a board cut from foil-laminated 1/32 inch thick sheet stock, .5 inches in width and 4 inches in length. The shield is designed to fit the 20 CBSA shielded cavity and is rated for use from 30 to 275 MHz. This shield provides excellent protection at these frequencies and is suitable for any application requiring a reliable, low cost RF shield.

The 20-CBSA-0.75X4.0X0.2 shield is constructed using an aluminum oxide ceramic-filled copper foil tape which is laminated between two sheets of copper foil. The copper foil acts as an electrical conductor, and the ceramic filler provides enhanced thermal and acoustic insulation. The lamination serves to reduce vibrations and other unwanted electromagnetic noise. In addition, the shield is coated with a thin layer of nickel-plated copper to provide additional protection from oxidation, corrosion, and other environmental factors.

The 20-CBSA-0.75X4.0X0.2 shield is designed to protect electronic equipment from electrical interference which may be causing undesired noise. This type of interference may be caused by external radio frequencies, such as those generated by cell phones, broadcast towers, and other sources. By shielding the equipment, the undesired signals are blocked from penetrating the area, reducing the interference and allowing the equipment to operate more effectively.

The 20-CBSA-0.75X4.0X0.2 shield is also designed to block heat which may build up due to excessive current drawn by the equipment. The aluminum oxide ceramic-filled copper foil tape is able to absorb the heat and dissipate it away from the equipment, thus reducing the temperatures inside the protected area. This allows for improved performance of the equipment and more reliable operation.

The 20-CBSA-0.75X4.0X0.2 shield is ideal for use in a variety of electronic applications, including wireless systems, cellular systems, satellite communication networks, and digital audio and video processing. In addition, it is suitable for use in automotive, aerospace, military, and medical devices where reliable shielding is required. This type of RF shielding also provides additional protection against lightning strikes and other sources of electrical interference.

The 20-CBSA-0.75X4.0X0.2 shield is a reliable and cost-effective solution for effective electromagnetic shielding. Its lightweight aluminum oxide ceramic-filled copper foil construction provides excellent protection from electromagnetic interference and helps to dissipate heat away from the protected area. In addition, the nickel-plated copper coating increases corrosion and oxidation resistance, making this RF shield ideal for use in a variety of electronic applications.
