SG125250D-48 Application Field and Working Principle

SG125250D-48, also referred to as a strip contact gasket, is a type of gasket specifically designed to provide an effective attenuation of electromagnetic interference, or EMI, between components in electronic devices. SG125250D-48 can be found in devices ranging from antennas to logic boards and passive components. This article will discuss the application field and working principle of the SG125250D-48 strip contact gasket.The application field of the SG125250D-48 strip contact gasket is varied, due to its use in diverse electronic devices. Specifically, it can be used where components need to be isolated from interfering RF signals or EMI. A typical application can be found in the base station of a cellular phone network. The SG125250D-48\'s unique design allows for effective attenuation of RF interference between the terminal antenna and components, such as the base station controller.The working principle of the SG125250D-48 strip contact gasket is based on its unique design. The strip consists of a thin polyester film with an adhesive backing and a layer of EMI-shielded contacts. This arrangement creates a conductive path that effectively attenuates EMI, thereby providing a uniform distribution of signal shielding.The strip contact gasket is also designed to provide electrical continuity between components, thereby ensuring a reliable connection. It consists of conductive stainless steel fingers that are sealed in a dielectric insulation material. This arrangement ensures a low-resistance conductive pathway between components, thus providing a reliable electrical connection. The dielectric insulation materials used in the construction of the strip contact gasket also ensure that the electrical continuity between components is maintained at a constant level, even if subjected to extreme temperatures or moisture.The SG125250D-48 strip contact gasket is designed with a high-reliability connection, and is an effective means of attenuating EMI. Its unique design allows for a reliable electrical connection between components in electronic devices, whilst at the same time providing effective EMI attenuation. Furthermore, its dielectric insulation material ensures that the integrity of the connection is maintained, even in extreme conditions.
