The 3M 1170 1/2" X 4"-100 is a shield applied to a wide variety of electronic and electrical components to provide electromagnetic interference (EMI) and radiofrequency interference (RFI) protection. The 3M 1170 provides both shielding and absorbing abilities, in addition to its attractive visual profile. The shielding characteristics provided by the 3M 1170 are based on Faraday’s Law of Induction.

Faraday\'s Law of Induction states that when a change in the electrical field is applied across the area within an enclosure, a voltage can be induced in the enclosure. This voltage, in turn, produces an electric current flowing in a circuit created by the shield, giving rise to a protective field that prevents electric fields from passing through it. The 3M 1170 is designed to take advantage of this phenomenon and provide maximum shielding effectiveness.

The 3M 1170 is an especially effective shield in networked systems in which multiple components are connected in close proximity. As an example, multiple motherboard components and an Ethernet cable may need to be kept on the same plane while limiting radiation. The 3M 1170 can provide both shielding and absorption properties when placed between the components and Ethernet cable, resulting in an overall reduction in field noise. Additionally, the 3M 1170 is malleable enough to be used to form wrap-around shields on components.

For applications in which the 3M 1170 is used to shield against high frequency radiation, the product may be combined with additional absorbing materials to absorb the energy so that it is not reflected back into the enclosure. For applications where the 3M 1170 is used to prevent interference from Electric and Magnetic fields, the product may be combined with additional absorbing material, such as foam and synthetic rubber, to reduce reflection and absorb the power.

The 3M 1170 is often used along with gaskets and other sealing materials to provide a dense seal against fumes, dust, and other particles. Additionally, the 3M 1170 may be used to provide EMC and EMI shielding in order to protect sensitive systems from external interference. The 3M 1170 can also be used to reduce crosstalk in audio applications, providing improved sound quality.

The 3M 1170 is an effective EMI and RFI shield that is readily available in both individual and pre-forms. It is an economical solution that provides effective shielding in a variety of applications. The 3M 1170 is a popular choice for shielding electronic components from electric fields, radiofrequency interference, and electromagnetic interference.
