SG125187D-48 is a series of contact and gasket materials from EMF Corporation used to reduce radio frequency interference (RFI) and electromagnetic interference (EMI) in electrical and electronic components and systems. The products are designed to absorb, dissipate, or shield RFI and EMI from invading systems via conduction, capacitive coupling, or induced electromagnetic current paths. SG125187D-48 series contact and gasket materials share many common characteristics, such as their multilayer construction and composition, which consist of an electrically conductive layer, an insulative layer, and a gasket material. The first layer is designed to provide excellent electrical contact between two components and also to resist the buildup of unwanted electrical noise. The second layer is designed to be both electrically non-conductive, while providing a degree insulation from EMI and RFI. The final layer is designed to provide a degree of mechanical support to the other components, while maintaining a low electrical noise profile.

The SG125187D-48 series contact and gasket materials share many uses. They are used as contact pads, fingerstocks, and as a variety of gasket materials in a variety of applications. Contact pads are mainly used in shielding enclosures, which reduce the electrical noise transmitted from one enclosure to another. Because these materials are electrically conductive, they form an excellent electrical connection between two shielded environments. Fingerstocks were historically used in shielded wires and cables, such as the shield termination and shielding effect of wires and cables. However, today they are mainly used to create a degree of mechanical support between two surfaces in order to reduce the passage of RFI and EMI through the wires and cables. Lastly, SG125187D-48 series contact and gasket materials are used as a variety of gasket materials in a variety of applications, such as the sealing of military-grade connectors.

SG125187D-48 contact and gasket materials are also used to create custom shielding solutions, such as the use of fingerstock and gasket material to design and construct a custom EMI filter for an application. In this case, the gasket material acts as a cushion to absorb the unwanted electrical energy, while the fingerstock helps to contain the energy within the shielding. This is done by providing an additional layer of protection against electromagnetic energy. The finger stock itself is designed to dissipate the energy and provide a degree of insulation between the shield and the component.

SG125187D-48 contact and gasket materials are widely used in a variety of applications, from military grade equipment to commercial electronics. They are also used to reduce the transmission of RFI and EMI in a variety of applications, including shielding enclosure systems, shielding of wires and cables, and the sealing of military-grade connectors. The variety of uses, along with the multi-layer construction and composition, make SG125187D-48 contact and gasket materials an ideal solution for reducing RFI and EMI in electrical and electronic components and systems.
