RFI and EMI - Shielding and Absorbing Materials.

3M 1125 1/2" x 3"-100 is a shielding and absorbing material designed to be used in a variety of applications including electronic equipment enclosures, laboratories, and medical equipment. It is formulated with a proprietary blend of two conductive and three absorptive layers to provide a combination of shielding and absorption.

The material has a low profile and is lightweight, helping make it ideal for applications where space or weight limitations prevent other shielding materials. It is also non-limiting, helping reduce the levels of interference in electronically sensitive areas. The material is well suited to be used in areas where both electromagnetic interference (EMI) and radio frequency interference (RFI) must be minimized.

The core of the material is a perforated conductor backed with an absorptive material that is sealed together with a fusible coating. This perforated conductor provides shielding against EMI and RFI. The absorptive material helps absorb any RFI energy that manages to get through the conductor. The fusible coating increases the flexibility of the shielding material and helps to ensure a good physical bond with the surface of the equipment it is applied to.

In order to maximize shielding effectiveness, 3M 1125 1/2" x 3"-100 must be applied in conjunction with other shielding materials. A first layer of EMI shielding, such as foil, should be applied to the surface to be protected. Then a layer of 1125 1/2" x 3"-100 should be applied, followed by a second layer of EMI shielding. This approach helps ensure that both EMI and RFI interference are addressed.

3M 1125 1/2" x 3"-100 is a versatile shielding and absorbing material that is well suited for a variety of applications. It is lightweight, low profile, and provides a combination of shielding and absorption. It should be used in combination with other shielding materials for maximum effectiveness.
